  • Editorial

    Intergovernmental meeting

    The Seventh Session of the Intergovernmental TechnicalWorking Group on Animal Genetic Resources for Foodand Agriculture took place in Rome in October 2012.1

    As discussed in the editorial of volume 51, one of themain tasks facing the Working Group was to review pro-gress made in the implementation of the Global Plan ofAction for Animal Genetic Resources2. The WorkingGroup welcomed the substantial progress made, butacknowledged that gaps remain to be addressed, particu-larly in terms of improving collaboration and the fundingof activities. Detailed information can be found in thedocument Synthesis progress report on the implementationof the Global Plan of Action for Animal GeneticResources 2012,3 which was prepared for the WorkingGroups meeting.

    The information presented in the Synthesis progress reportwas also used to prepare a set of three posters:

    1. Strategic priorities of the Global Plan of Action forAnimal Genetic Resources4

    (overview of the strategic priorities of the Global Plan ofAction at national, regional and global levels);

    2. Status of implementation of the Global Plan of Actionfor Animal Genetic Resources5

    (indicators for each strategic priority at national, regionaland world levels); and

    3. Colour scheme expressing levels of implementationof the Global Plan of Action for Animal GeneticResources6

    (colour scheme used to illustrate the indicators).

    The Working Groups agenda also included the prep-aration and timing of an update of The State of theWorlds Animal Genetic Resources for Food andAgriculture. It had been foreseen that a second reportwould be presented to the Commission on GeneticResources for Food and Agriculture in 2017, 10 yearsafter the rst report was published. However, because ofthe heavy workload scheduled for the CommissionsSixteenth Regular Session in 2017, the Working Groupwas asked to consider the possibility of advancing thepreparation of the second report by two years, i.e. recom-mending that the Commission request FAO to present the

    report to the Commissions Fifteenth Regular Session in2015, which would mean having a draft ready for reviewby the Working Group in late 2014. The WorkingGroup recommended that the Commission agree to thisschedule. This volume of Animal Genetic Resourceswent to press before the Commissions meeting in Aprilat which the Working Groups recommendation was tobe considered.

    The second report, whether presented in 2015 or later,would be regarded very much as an update of the rstreport, presenting the changes that have occurred duringthe intervening years in the status of animal geneticresources and their management, as well as the latest scien-tic developments in relevant elds. Reporting burdensplaced on countries would be kept to a minimum andinformation on the state of animal genetic resources man-agement at national level obtained via specic question-naires rather than by requesting more elaborate countryreports of the type prepared for the rst report.

    The Working Groups agenda also included a review ofimplementation of the Funding Strategy for theImplementation of the Global Plan of Action for AnimalGenetic Resources (the meeting coincided with theannouncement of the rst set of projects chosen to receivesupport under the Funding Strategy);7 the roles ofsmall-scale livestock keepers in the conservation and sus-tainable use of animal genetic resources; targets and indi-cators for animal genetic resources; the status and trends ofmicro-organisms for ruminant digestion; and a review ofthe outcomes of the First Session of the CommissionsWorking Group on Access and Benet Sharing.

    Thirty years of the Commission

    As well as being a potentially busy year for the inter-national animal genetic resources community, 2013 isalso the thirtieth anniversary year of the Commission.Founded in 1983 as the Commission on Plant GeneticResources for Food and Agriculture, the Commissioncan look back on a long series of achievements, includingthe negotiation of the International Treaty on Plant GeneticResources for Food and Agriculture and the preparation ofState of the World Reports and Global Plans of Action inthe plant and animal genetic resources sectors. TheCommissions work has expanded from its initial focuson crops, rst to animals (livestock) and later to forests,aquatic genetic resources, and invertebrates and micro-

    La Septime Runion du Groupe de Travail TechniqueIntergouvernemental sur les Ressources Zoogntiquespour lAlimentation et lAgriculture sest tenue Romeen Octobre 2012.1 Comme il a t dit dans lditorial duvolume 51, une des principales tches que le Groupe deTravail a d confronter a t celle dexaminer les progrsraliss dans la mise en uvre du Plan dActionMondial pour les Ressources Zoogntiques.2 Le Groupede Travail a fait bon accueil au substantiel progrsralis, en admettant cependant quil existe encore deslacunes combler, notamment en ce qui concernelamlioration de la collaboration et du nancement desactivits. Pour plus de dtails, veuillez consulter le docu-ment Synthesis progress report on the implementation ofthe Global Plan of Action for Animal Genetic Resources 2012 (Rapport intrimaire de synthse sur la mise enuvre du Plan dAction Mondial pour les RessourcesZoogntiques 2012),3 qui a t prpar pour larunion du Groupe de Travail.

    Linformation prsente dans le Rapport intrimaire desynthse a aussi t utilise pour prparer un ensemblede trois afches :

    1. Strategic priorities of the Global Plan of Actionfor Animal Genetic Resources4 (Priorits stratgiquesdu Plan dAction Mondial pour les RessourcesZoogntiques; vue densemble des prioritsstratgiques du Plan dAction Mondial aux chellesnationale, rgionale et mondiale);

    2. Status of implementation of the Global Plan of Actionfor Animal Genetic Resources5 (tat de mise enuvre du Plan dAction Mondial pour les RessourcesZoogntiques; indicateurs pour chaque prioritstratgique aux niveaux national, rgional et mondial); et

    La prparation et planication dune mise jour de Ltatdes Ressources Zoogntiques pour lAlimentation etlAgriculture dans le Monde taient aussi lagendadu Groupe de Travail. Il a t prvu de prsenter undeuxime rapport la Commission des Ressources

    Gntiques pour lAlimentation et lAgriculture en 2017,dix ans aprs la publication du premier rapport.Toutefois, en raison de la lourde charge de travailprogramme pour la Seizime Runion Ordinaire de laCommission en 2017, il a t demand au Groupe deTravail de prendre en considration la possibilit davancerla prparation du deuxime rapport de deux ans,cest--dire de conseiller la Commission quelle sollicite la FAO de prsenter le rapport lors de la QuinzimeRunion Ordinaire de la Commission en 2015, ce quiimpliquerait quune bauche serait soumise lexamendu Groupe de Travail vers la n de lanne 2014. LeGroupe de Travail a recommand la Commission dac-cepter cette programmation. Ce volume de RessourcesGntiques Animales a t mis sous presse avant larunion de la Commission du mois davril, au cours delaquelle la recommandation du Groupe de Travail devaittre examine.Quil soit prsent en 2015 ou ultrieurement, le deuximerapport constituera une mise jour du premier rapportdautant plus quil prsentera les changements survenusentre-temps pour ce qui est de ltat des ressourceszoogntiques et leur gestion et les derniersdveloppements scientiques dans les domaines perti-nents.

    Encuentro intergubernamental

    La Sptima Reunin del Grupo de Trabajo TcnicoIntergubernamental sobre los Recursos Zoogenticos parala Alimentacin y la Agricultura se celebr en Roma enOctubre de 2012.1 Tal y como se coment en el editorialdel volumen 51, una de las principales tareas que abordel Grupo de Trabajo fue la revisin de los progresos alcan-zados en la aplicacin del Plan de Accin Mundial sobrelos Recursos Zoogenticos.2 El Grupo de Trabajo acogicon agrado el considerable progreso realizado, peroadmiti que quedan carencias por cubrir, en concreto enmateria de mejora de la colaboracin y del nanciamientode las actividades. El documento Synthesis progress reporton the implementation of the Global Plan of Action forAnimal Genetic Resources 2012 (Informe de sntesisde los progresos realizados en la aplicacin del Plan deAccin Mundial sobre los Recursos Zoogenticos 2012),3 que fue preparado para la reunin del Grupo deTrabajo, recoge una informacin ms detallada.

    La informacin presentada en el Informe de sntesis de losprogresos realizados tambin ha sido usada para prepararun conjunto de tres psteres:

    1. Strategic priorities of the Global Plan of Action forAnimal Genetic Resources4 (Prioridades estratgicasdel Plan de Accin Mundial sobre los RecursosZoogenticos; resumen general de las prioridadesestratgicas del Plan de Accin Mundial a nivel nacio-nal, regional y mundial);

    2. Status of implementation of the Global Plan of Actionfor Animal Genetic Resources5 (Estado de aplicacindel Plan de Accin Mundial sobre los RecursosZoogenticos; indicadores para cada prioridadestratgica a nivel nacional, regional y mundial); y

    3. Colour scheme expressing levels of implementation ofthe Global Plan of Action for Animal GeneticResources6 (Escala de color de referencia para elgrado de implementacin del Plan de Accin Mundialpara los Recursos Zoogenticos; escala de color usadapara ilustrar los indicadores).

    En la agenda del Grupo de Trabajo tambin se incluyeronla preparacin y planicacin de una actualizacin de LaSituacin de los Recursos Zoogenticos Mundiales parala Alimentacin y la Agricultura. Se ha previsto lapresentacin de un segundo informe a la Comisin deRecursos Genticos para la Alimentacin y la

    Agricultura en 2017, diez aos despus de la publicacindel primer informe. No obstante, debido a la fuerte cargade trabajo programada para la Decimosexta ReuninOrdinaria de la Comisin en 2017, se ha pedido alGrupo de Trabajo que considere la posibilidad de adelantardos aos la preparacin del segundo informe, es decir reco-mendar a la Comisin que pida a la FAO que el informe sepresente en la Decimoquinta Reunin Ordinaria de laComisin en 2015, lo cual signicara que habra quetener un borrador listo para ser revisado por el Grupo deTrabajo a nales de 2014. El Grupo de Trabajo aconsejque la Comisin aceptara esta programacin. Este volumende Recursos Genticos Animales fue llevado a la imprentaantes del encuentro de la Comisin del mes de abril, en elcual se deba considerar la recomendacin del Grupo deTrabajo.El segundo informe, ya sea presentado en 2015 o poster-iormente, supondr en gran medida una actualizacin delprimer informe puesto que presentar los cambios acaeci-dos, en los aos de intervalo, en el estado de los recursoszoogenticos y en su ordenacin, as como los ltimosdesarrollos cientcos en los campos pertinentes. Lacarga que supone para los pases la elaboracin deinformes sera reducida a un mnimo. As, la informacinsobre la situacin de la gestin de los recursoszoogenticos a nivel nacional sera recabada a travs decuestionarios especcos en vez de solicitando a lospases informes detallados como los que se prepararonpara el primer informe.

    La agenda del Grupo de Trabajo tambin contempl unarevisin de la implementacin de la Estrategia deFinanciacin para la aplicacin del Plan de AccinMundial sobre los Recursos Zoogenticos (el encuentrocoincidi con el anuncio del primer conjunto de proyectosseleccionados para ser apoyados por la Estrategia deFinanciacin);7 el papel de los pequeos ganaderos en laconservacin y uso sostenible de los recursoszoogenticos; metas e indicadores para los recursoszoogenticos; situacin y tendencias respecto de los micro-organismos relacionados con la digestin de los rumiantes;y una revisin de los resultados de la Primera Reunin delGrupo de Trabajo de la Comisin sobre el Acceso y laDistribucin de Benecios.

  • Morphological traits of duck and geese breeds ofWest Bengal, IndiaSandip BanerjeeB-1/87, KALYANI, Nadia, West Bengal, India, Pin-741235. Presently: School of Animal and Range Sciences,Hawassa University, Ethiopia

    SummaryThe study pertains to phenotypic characterization of some breeds of duck (common white duck and Indian runner duck), Muscovyducks (black and white feathered and sepia feathered) besides two breeds of geese (white and brown feathered and white feathered)reared in the state of West Bengal (India). The study was conducted at ve locations of the state and comprised 1395 ducks and600 geese. The data were analysed statistically using mainly descriptive statistics, the differences in mean were analysed usingDuncans multiple range test. Both qualitative and quantitative traits were considered in the study. The qualitative traits were shankcolour, bill colour, colour of the feathers, skin colour, egg shell colour, the presence or absence of beans, body carriage, bill typeand colour of the eyes, while the quantitative traits included in the study were weight of the ducks and weight of the eggs. Some pro-duction traits such as numbers of eggs laid per year and dressing percentage of the drakes and ganders of each breed too have beenstudied. The ducks and geese are raised under semi-intensive management system and mostly depend on scavenging for their nutri-tional needs. This results in poor egg production and at times loss of stock because of diseases. The study regarding average egg pro-duction indicated that the Muscovy ducks and the geese have poor egg production, whereas the Indian runner followed by the commonwhite duck are potentially the best. The ducks are important source of earnings for the small holder farmers and are raised both for meatand eggs, while the geese are reared mostly for ornamental purpose. However, the populations of the ducks are fast dwindling becauseof avian inuenza in the region and because restocking is mostly being carried out with less adapted Khaki Campbell ducks. This hap-pens mainly because the government farms that were responsible for providing the ducklings for restocking maintain Khaki Campbellducks and do not have the parental stock of the native duck breeds, while restocking of the Muscovy ducks and geese are carried out bythe rearers themselves. There are also no prevailing breeding programmes to conserve, select, maintain and distribute the native breedsof duck and geese. Hence, it is of earnest importance to conserve the avian genetic resources before the population dwindles further.

Les canards sont la source importantede gains pour les petits agriculteurs de support et sont levs pour la viande et les oeufs pendant que les oies sont surtout levespour le but dcoratif. Toutefois, les populations des canards diminuent rapidement en raison de la grippe davian dans la rgion etque le regarnir est surtout excut avec les canards de Campbell de moins de Kaki adapt. Ceci a t principalement excut parceque les fermes de gouvernement qui taient responsables de fournir les canetons pour regarnir maintiennent les canards deCampbell de Kaki et nont pas le stock parental des espces de canard natales en regarnissant pour les canards de Muscovy et lesoies sont excut par le rearers se.

Los patos y los gansos son levantados bajo sistema medio inten-sivo de gestin y dependen en su mayor parte de la barrer para sus necesidades nutricionales. Esto tiene como resultado la produccinpobre de huevo y a veces prdida de acciones debido a enfermedades. El estudio con respecto a la produccin de huevo de promedioindica que el pato de Muscovy y los gansos tienen la produccin pobre de huevo donde como el corredor indio seguido por el patoblanco comn es potencialmente el mejor. Los patos son fuente importante de ganancias para los pequeos granjeros de poseedor y sonlevantados para carne y huevos mientras los gansos son criados en su mayor parte para propsito decorativo. Sin embargo, las pobla-ciones de los patos menguan rpidamente debido a la gripe aviar en la regin y que la reabastecer es llevada a cabo en su mayor partecon patos menos adaptados de tela de uniforme Campbell. Esto fue llevado a cabo principalmente porque las granjas del gobierno quefueron responsables de proporcionar los patitos para la reabastecer mantienen que patos de tela de uniforme Campbell y no tienen lasacciones paternales de las castas nativas de pato al reabastecer para los patos de Muscovy y gansos son llevados a cabo por el rearers smismos.

    Introduction

    The state of West Bengal is situated between 212524and 271315 N latitudes and 854820 and 895304E longitudes. The state shares its borders withBangladesh, Bhutan and Nepal and four other Indianstates, such as Orissa, Jharkhand, Assam and Sikkim.

    The climate of the state is predominantly hot and extre-mely humid except for the Northern hilly district ofDarjeeling. The state has the highest population densityin the country and it is estimated that a total of 72 percentof the human population of the state reside in the ruralareas. The residents in the rural areas depend on agricul-ture and allied activities for their livelihood (NABCONS2010). Most of the farmers have small land holdings andthus small-scale poultry plays a substantial role in ensuringfood security for the family besides assisting in povertyreduction. The villages in the state have water bodiesthat serve multiple purposes (source of water for drinking,bathing and also washing clothes and utensils) for majorityof the residents. According to Besbes (2009), globally theducks contribute 11 percent and geese 9 percent of the glo-bal poultry sector. However, in spite of the signicantlyhigh contribution of the indigenous ducks to the ruraleconomy (especially in the coastal regions) of India,research and developmental studies on indigenous duckand geese breeds are by and large at its infancy.Tixier-Boichard, Ayalew and Jianlin (2008) suggestedthat characterization and inventory of poultry geneticresources are needed in countries where clearly denedpoultry breeds are yet to be identied; hence properly

    designed scientic studies on indigenous duck and geesebreeds of India need to be prioritized.

    According to the reports of DAHDF (2006), the state ofWest Bengal has the highest duck population in India.The annual increase in duck population in West Bengalbetween 1997 and 2003 indicate that the annual growthrate for the native breeds/types was assessed to be 22.67percent, while there was a reduction of 40.3 percent inthe numbers of exotic duck breeds. The national trendregarding the growth of the ducks too indicated similartrend (19972003), while the numbers of native ducksincreased by 21.35 percent, those of the exotic onesdecreased by 65.87 percent during the same periodDAHDF (2006). The state of West Bengal also possesses75 percent of the total layer type duck breeds in thecountry; in spite of having such a large population, theaverage number of eggs per duck is slightly lower thanthose of the national average of 106 eggs per year,which may be attributed to the genotypes and managementof the ducks and geese. Most of the rearers belong to econ-omically challenged section of the society and are unableto provide much needed balanced nutrition, proper man-agement and health services. Still the state contributedaround 70 percent of the total number of duck eggs con-sumed in the country which may be attributed to thelarge duck population as mentioned earlier. The ducksare mostly seen foraging in such water bodies whichmay be privately owned or even communal in nature.The ducks are reared both for their meat and eggs, while

    2 S. Banerjee

  • geese are mostly reared for ornamental purpose althoughsome people do consume geese meat.

    However, there has since been a reduction in the number ofnative duck population in many districts of the WestBengal because of the outbreak of avian inuenza in2007 and again in 2008. The outbreak of this diseaseresulted in culling of all domesticated avian species. Therestocking was later carried out by introduction of exoticduck breeds (mainly Khaki Campbell) under the guidanceof the authorities of Animal Resources DevelopmentDepartment. The restocking has resulted in dilution ofthe duck genetic resources in the state in general and inthe affected areas in particular.

    The contribution of the ducks can be assessed by the fact thatalmost every rural household have a couple of them andduck eggs fetch higher price compared with those from thehens. The other reason why the native ducks are preferredover the exotic duck breeds is because their eggs fetch higherprice. Traditional cuisines prepared of duck eggs and meat isconsidered as delicacies by the residents of the state. Theeggs of the native duck breeds are preferred by the consu-mers for their taste, pigmentation and suitability for tra-ditional cuisines. The eggs of the geese and that of theMuscovy ducks are seldom consumed by the rearers as theeggs are mostly used for restocking purpose.

    The observation nds analogy with the observations ofHalder, Ghoshal and Samanta (2007) from West Bengaland Gajendran and Karthickeyan (2009) from TamilNadu, India, FAO (2011). The preference of nativeducks over the improved breeds and hybrids has alsobeen reported by Jalil, Begum and Nahar (1993) andRehman et al. (2009).

    Materials and methods

    The study was conducted in ve districts of West Bengalnamely Midnapur (East) (MID), 24 Parganas (South) (24P (S)), 24 Parganas (North) (24 P (N)), Nadia (NAD)and Murshidabad (MUR) (Table 1). The three gram pan-chayats (local administrative bodies) were selected ran-domly from each district. Thereafter, villages within agram panchayat were selected purposively keeping inmind the fact that no ducklings of exotic types were dis-tributed in the selected villages by the local authorities inthe near past. The households selected for interviewswithin the villages too were selected purposively keepingin mind that the owner reared only the native ducks, thehouses having exotic or even seem to be cross-bredducks were not included in the survey and the adjacenthouses from where the ocks can intermingle were alsonot taken into consideration. This led to few numbers ofhousehold per village. The families who had recently pro-cured native ducks from nearby markets or received themas gifts from acquaintances too were not taken intoaccount. The percentage of different duck and geese breeds

    in the study vis--vis the total duck population as a wholein the areas studied is presented in Table 2.

    The result of the study comprises both qualitative andquantitative traits of 1395 ducks and 600 geese of variousbreeds which were/are reared in the studied villages. Thedescription of qualitative traits considered in this studywere assessed according to the guidelines suggested byManuel (2008). The qualitative traits studied were shankcolour (white, blue and yellow), bill colour (pink white,orange, yellow, white and brown), colour of the feathers(specic colours or mixed), skin colour (white, yellow orgrey), egg shell colour (white, cream or blue), the presenceor absence of beans and colour of beans (white, black ordark brown), shape of bill (uniform or saddle), body car-riage (horizontal, slight upright or upright) all of whichwere recorded through visual observation, while the quan-titative traits were weight of the ducks and weight of theeggs. The age of the ducks was not considered as a par-ameter in the study and only adult ducks were consideredfor the quantitative traits. The results in Tables 3 and 4have been presented separately for drakes and ducks andalso ganders and geese because this would help the auth-orities to make separate selection strategies for males andfemales. This is also because the selection intensity forthe two sexes differs; hence such information would beuseful for further conservation and breeding programmes.

    The rearers were interviewed using a pretested questionnairewhich pertained to the prevalent duck husbandry practices inthe different study areas; the questionnaire also included thequestions pertaining to housing feeding, watering, diseasemanagement/treatment, marketing of the eggs and ducks,role of different family members in duck husbandry prac-tices, breed preferences for eggs and meat purposes, averagenumber of eggs laid by a duck, hatchability and mortality.The price of the ducks and eggs were also taken into con-sideration to assess the importance of the ducks among therearers. The ducks, geese and the eggs were weighed onan electronic balance with an error margin of 0.5 g. Thedressing percentage was assessed by slaughtering the drakesand ganders followed by hot water scalding and eviscerationof the gut contents including the skin. The dressing percen-tage was calculated according to the method suggested bySahin and Yardimci (2009). The results were analysed stat-istically using SPSS v-12 for Windows (2003), the meansand standard deviations (SD)/standard errors (SE) were com-puted using descriptive statistics, the means for the quantitat-ive traits were compared using Duncans Multiple RangeTest and the values were considered signicant at p < 0.05.

  • Results

    Physical characteristics

    No signicant differences were observed between cowsand bulls (Table 2). Figures 2 and 3 show examples ofthe Azikheli cow and bull, respectively.

    Morphometric characteristics

    Table 3 shows that Azikheli cows have a signicantly largerheart girth, wider forehead, longer horns and longer neckthan bulls. On the other hand, bulls have a signicantlylonger body, thicker horns and neck, and larger hoovesthan cows. Horns are at laterally, and directed backwardsand slightly upwards without twisting. The upward curveis variable and gives the horn a sickle or semi-sickle appear-ance. This is a specic characteristic of the Azikheli breed.

    Discussion

    Buffaloes show a variety of coat colours, with most riverinebuffaloes being black to ashy grey (Soysal et al., 2007),while the coat colour of swamp buffaloes ranges fromgrey to completely black, with very few having a whitecoat (Miao et al., 2010). The common buffalo breeds ofPakistan are predominantly black (Khan et al., 2005) withonly occasional occurrence of brown coats (8 percent) inNili-Ravi and Kundi buffalo (Maqsood, 1980). A darkcoat causes heat intolerance because it absorbs a greatdeal of solar radiation and this is one of the reasons whydark-coated breeds wallow in swamps (Marai & Haeeb,2010). The dominant brown coat colour (62.04 percent) inAzikheli seems to be an adaptation to the mountainousenvironment, where swamps are not available.

    The farmers of the area prefer Sra Chargai (a brown coatcolour with a completely white forehead) to Sra Tikai (abrown coat colour with a white spot on forehead).

    The non-signicant difference between the colour patternsof various body parts of the Azikheli cow and bull may bedue to the prevalence of natural selective forces over socialpreferences in determining coat colour in bovines (Seoet al., 2007).

    Information on morphological characteristics is helpful inensuring effective management and conservation of animal

  • genetic resources with a view to obtaining phenotypicallypure local genetic resources for future selection and breedimprovement strategies (Yakubu et al., 2010). Berthoulyet al. (2009) recorded heart girth, body length, height at with-ers, neck circumference, ear length and thorax depth asappropriate variables to differentiate the local Vietnameseswamp buffalo population from other buffalo breeds. ForPakistani buffalo breeds, such information is limited toheart girth, body length and height at withers, hence com-parative measurements shown in Table 4 are limited tothese three parameters.

    Comparison of these parameters between the two breedsreveals that the body size of Azikheli is smaller than thatof Nili-Ravi, a breed that is well adapted to life in theplains. Owing to their low maintenance requirements(Ibrahim & Brannang, 2001), smaller animals are consideredless susceptible to fodder shortages (Hall, 1998) and are ableto move more easily and rapidly on mountain slopes (Oumaet al., 2004). As the Azikheli is native to mountain valleyswith high seasonal uctuations in the availability of feedresources, its smaller body size can be interpreted as anadaptive trait to fodder uctuations, as well as to grazingin mountain terrain and transhumance. Sexual size dimorph-ism has been observed in the present study, with a longerbody of the bull, whereas the cow has a large heart girthsize and wider head at the eyes.

    Conclusion

    Given its small body size and brown coat colour, it appearsthat the breed is well adapted to mountain slope grazing andvariable availability of feed resources. Differentiatingcharacteristics of the Azikheli include the dominant browncoat colour and the sickle-shaped horns. In view of climatechange and the likelihood of an increase in the frequency ofextreme weather events in mountain regions in particular,livestock breeds like the Azikheli could prove to be a valu-able resource for mountain dwellers in terms of adaptationto such weather extremes. The morphometric characteristicsdescribed here provide a basic description of the breed, butstudies on genotypic characteristics and plans for in situparticipatory conservation of the Azikheli are suggestedmeasures to secure its appropriate conservation.

    SummaryAn exploratory survey of local cattle populations of Gamo Goffa Zone in south-western Ethiopia was conducted between April 2011and May 2012 to identify and phenotypically characterize cattle populations. Ten focus group discussions with key informants as wellas phenotypic data from sample mature animals were used to generate data, including quantitative trait data from 560 animals and quali-tative trait data from 867 animals. Findings from focus group discussions revealed that, even if local cattle are found widely distributedthroughout the study area, they are not known by any common name or breed type. Results from analysis of variance (ANOVA) oncontinuous variables showed signicant (P < 0.0001) differences between sites. Tukeys multiple mean comparison test showed thateach quantitative traits were signicant (P < 0.0001) for sites. Chi-square test was also signicant (P < 0.0001) for most of the categ-orical variables per sites. Based on a discriminant analysis, sample populations were classied into their respective sites with overallhitting rate was 63.15 percent for females and 74.89 percent for males. Canonical discriminant (CANDISC) analysis showed quanti-tative traits and Mahalanobis distances between sites were signicant (P < 0.0001). The stepwise discriminant (STEPDISC) analysisfor both populations showed that most variables had signicant (P < 0.0001) power in explaining phenotypic variation. These infor-mation from focus group discussions and phenotypic variation analyses led to identication of two cattle populations that deemedto be distinct breed types (Gamo highland and lowland). Thus, indigenous cattle population of the study area was not homogenouson their phenotypic features, and further genetic characterization should be done to conrm their genetic distinctiveness.

    Introduction

    Ethiopia is believed to have the largest livestock popu-lation in Africa. Results of the latest livestock populationcensus showed about 53.4 million heads of cattle (CSA,2010/11), without including cattle populations of threezones of Afar and six zones of Somali Regions. Themajority (99.26 percent) of the cattle population are localbreeds, which are found in rural areas under subsistencemode of farming. Cross-bred and pure exotic cattleaccounted for about 0.64 and 0.1 percent, respectively(CSA, 2010/11).

    Apart from the large cattle population widely distributedthroughout the country, the multiple production and ser-vice functions of cattle are crucial in the livelihoods offarmers and pastoralists. They serve as sources of milk,meat, hide, draft power and manure as well as contributeto nutrient recycling at the farm level (Getachew andGashaw, 2001). Moreover, at the level of the nationaleconomy, the livestock sector contributes 26 percent ofthe agricultural gross domestic product (GDP) and 12 per-cent to the national GDP (CSA, 2008/09).

    Based on the available information as summarized inDomestic Animal Genetic Resources Information System(DAGRIS) database (DAGRIS, 2011) there are 33 recog-nized indigenous cattle breeds in Ethiopia. Lately somemore breed types have been identied and reported, suchas the Wegera, Dembia and Mahibere-silassie breeds inthe north-west (Wuletaw, 2004), Abergalle and Irob cattlebreeds in the north (Zerabruk and Vangen, 2005), GojjamHighland zebu and Fogera breeds in the central highlands(Getachew, 2006) and Wollo Highland, Raya Sanga andAfar Sanga in the north-east (Tadesse, 2005). However,only a small number of recognized cattle breed typeshave a fair description of their physical appearance, indi-cations of their level of production, reproduction and gen-etic attributes (Ayalew et al., 2004). Owing to lack ofspecic information, cattle of the present study area aregenerally referred to in the existing literature as Goffa

    zebu or Goffa Dwarf (Epstein, 1971; Payne and Hodges,1997; Rege and Tawah, 1999). This does not reect thecurrent phenotypic diversity of the cattle populations inthe Gamo Goffa zone of south-western Ethiopia.

    Phenotypic as well as genetic characterization of indigen-ous livestock genetic resources provides the basis for anylivestock development intervention. Clearly, sustainableutilization of local breeds is the best means of conservingthese genetic resources. The rst essential step towardssustainable utilization of these resources is to identify themajor breed types, establish their population size as wellas their geographical distribution and describe their typicalqualitative and quantitative phenotypic traits (Negussieand Ayalew, 2002). On that basis, the present study wasconducted to survey local cattle types in the Gamo Goffazone to test the general hypothesis that the local cattlepopulations of this zone are phenotypically homogenous.

    Materials and methods

    Description of study area

    This study was conducted in Gamo Goffa zone of south-western Ethiopia. Gamo Goffa zone is one of 13 zonesof the Southern Nations, Nationalities and PeoplesRegional State (SNNPRS) and consists of 15 rural districtsand two town administrations. It is situated near the centreof the region around 557671N latitude and 36373798E longitude. Its general elevation ranges from 600to 3500 m asl; it receives 6001600 mm rainfall perannum and annual temperature ranges from 10C to 34C (Gamo Goffa zone ARDD, 2010). Agro-ecological fea-tures of each study sites are presented in Table 1 below.

    The topography of the zone is characterized by undulatinglandscapes that favour the existence of different climaticzones. The total human population of the zone was

  • reported as about 1.6 million (CSA, 2008/09) with a popu-lation density of 80 inhabitants per km2.

    The farming practices are mainly mixed croplivestocksystems, with crops being more dominant in the higheraltitude areas and livestock being more signicant in low-land areas. According to CSA (2010/11), the estimatedlivestock population and beehives of Gamo Goffa zonewere 1 438 752 cattle, 800 704 sheep, 336 941 goats,128 054 equines, 1 050 744 chickens and 60 996 beehives.

    Indigenous cattle populations in the Gamo Goffa zone andhouseholds keeping cattle constitute the study population.

    Sample size and sampling method

    To dene the sampling frame, available background infor-mation on the existence of phenotypically unique cattlepopulations in Gamo Goffa zone was surveyed throughsingle rapid exploratory eld visits to the study areacoupled with focus group discussions and review of avail-able secondary information. Based on that information, 15rural districts of the study zone were categorized into threegroups matching three presumably distinct cattle popu-lation types. These were cattle populations of highlands,mid altitude areas and the lowland area. Three sample dis-tricts (Bonke, Chencha and Boreda) from highlands andtwo districts (Arba-Minch-Zuria and Mirab-Abaya) fromlowlands were selected for actual data collection. Cattlepopulations of the mid-altitude areas did not show distinctfeatures that make them different from those of the high-land and lowland areas, and instead appeared to have inter-mediate features of other two types. Therefore, sampleswere not taken from mid-altitude districts. Five study dis-tricts were selected purposively taking into account thedominant agro-ecological zone of the districts, localknowledge on cattle population types and size of the cattlepopulation.

    Linear body measurements were taken from 560 matureanimals that were randomly selected from herds of repre-sentative households. Data on qualitative body form andshape were taken from a total of 867 animals (Table 2).The target number of sample cattle for a study site was50100 adult cows and about 30 bulls (FAO, 2012).Local cattle populations from similar agro-ecology wereconsidered as similar in their phenotypic features, whichwere later veried by outcomes of focus group discussions.

    In order to base the phenotypic characterization on themature body size of sample populations, morphometricmeasurements were taken from animals of at least 3years of known age, or those with all their milk teetherupted (i.e. full mouth). Elders, village leaders and indi-viduals with extensive knowledge on unique history ofexisting cattle populations were selected in consultationwith local agricultural extension workers for focus groupdiscussions.

    Data collection methods

    Focus group discussionPreliminary eld visits were made after gathering second-ary data from local livestock extension staff about the typeand distribution of indigenous cattle types in the studyarea. Then key informant focus group discussions wereheld with representatives of farmer groups, extensionstaff and the district administration ofcers. A total often focus group discussions were held two per site,each having 812 farmers plus a representative of theextension staff. The researcher facilitated the discussionat all sites. The main points for discussion included indi-genous knowledge about history of origin and introductionof existing cattle types, distinctive features of the cattletypes as well as their desirable and undesirable character-istics, utility and status of the existing cattle populationsand other information related to indigenous cattle.

    Observations and linear body measurementsMajority of both quantitative and qualitative variablesrecorded in this study were adapted from the standardcattle breed descriptor list of FAO (2012). In addition,FAO (1984, 1986) cattle breed descriptor lists that wereextensively reviewed and applied in Ethiopia (Wuletaw,

    Depending on FAO (2012) guideline and identied cattlepopulation type, their distribution in the study area, 185mature adult males (both intact and castrated) and 375 hei-fers and cows were randomly selected for morphometricmeasurements. Therefore, a total of 569 female and 298male cattle were sampled for recording their qualitativetraits. A total of 16 qualitative traits were observed: coatcolour pattern, coat colour type, facial prole, muzzle col-our, presence of horn, horn shape, horn orientation, earshape, ear orientation, rump prole, facial prole, humpshape, hump location, naval ap size, udder size and teatsize. Similarly, 15 quantitative traits were measured indifferent age categories of adult animals. Quantitative traitsconsidered include: body length, height at wither, heartgirth, neck length, ear length, tail length, horn length, pel-vic width, hump length, hock circumference, canon bonecircumference, dewlap width, preputial sheath width, muz-zle circumference and navel ap length. Measurementswere taken from each trait using textile tape measurementin centimetre unit. Heart girth was measured in the earlymorning before the animals were taken to grazing andwatering areas.

    Data management and statistical analysisAll data were entered, cleaned and managed using MSExcel worksheet. Box plots, scatter plots and tests ofnormality were done to check normality of quantitativevariables prior to taking data to analysis.

    Information compiled from focus group discussions wassummarized and synthesized to describe the origin, distri-bution, major characteristics and status of the respectivecattle populations.

    Qualitative data collected were subjected to the frequencyprocedure of SAS (2002) version 9.0. Chi-square testswere employed to test for the difference between the fac-tors of interest between sites. The pair-wise comparisonsfor each of the categorical variables across sites based onP-value were derived from Bonferronis correction(Petrie and Watson, 1999).

    The importance of each quantitative variable in explainingphenotypic differences between sample cattle populationsof the ve sites was examined using the generalized linearmodel (GLM) of SAS (2002). The generated site leastsquares means of each of the variable were then comparedusing Tukeys test of multiple comparison (Klockars,Hancock and McAweeney, 1995). Considering knownphysiological differences among female and male animalsin the measured quantitative variables, data were analysedseparately for the two sex groups. The following modelwas used for analysing quantitative phenotypic variationbetween the female sample populations by consideringsite and parity as xed main effects:

    Yijk = m+ Si + Pj + eijk ,

    where Yijk is the observed value of the linear bodymeasurements, is the overall mean, Si is the xed effectof site i (i = 1. . .5), Pj is the xed effect of parity j ( j =1. . .3), where parity was categorized as 02 = 1, 34 = 2and >4 = 3, and eijk is the residual erro
