Animal Resources in Oman: Livestock Statistics

Species Population

Goats 1,619,990

Cattle 313,580

Sheep 380,000

Camels 124,520

Donkeys 28,500

Total 2,466,590

FAOSTAT (2008-9)

Animal Resources in Oman: Cattle

North Oman Cattle Batina coastal planes Interior; Sharqiyah; Dhahira

Characteristics: Brown – dark brown Small size; Short horns Low milk yield; Disease

tolerant Systems of production

Small farms House keeping Zero grazing Dairy animal

Challenges Small herds; Traditional rearing Lack of characterization AI with Jersey

North Oman bull (Rumais)

North Oman cow (Interior)

Animal Resources in Oman: Cattle

South Oman Cattle (Dhofari) Jabal (Hills) Salalah plains

Characteristics: Black color dominant Small to medium size Short horns Low milk yield Disease tolerant Aggressive

Systems of production Range grazing (monsoon) Zero grazing (dry season) Dairy/beef animal Calves marketed in the north

Challenges Lack of characterization AI with Friesian

South Oman bull (Rumais)

South Oman cows grazing khareef range (Dhofar)

Animal Resources in Oman: Goats

Batina goat

South Sharqiyah goat

Most common Omani goat breeds

Animal Resources in Oman: Chicken

Numbers and distribution Characteristics

Mixed types No distinct breeds or strains Naked neck

Uses (meat, eggs) Systems (traditional) Production

Poor Preferred

Challenges Cross breeding (Fayoumi,

Indian, etc.)

Animal Resources in Oman: Donkeys

Numbers and distribution Unknown Hills (JA, Hijr, Sharqiyah

Feral Characteristics Uses

Animal Production Systems in Oman Traditional:

Nomadic Transhumant Shawawi Village Small farms Hill rearing

Commercial (cattle, poultry)

Animal Production Systems in Oman

Modern: Dairy Poultry Goat ! Beef !

Animal Production Systems in Oman

Livestock marketing in Oman

Traditional: Auction Well-organized system High prices

Transportation Open trucks Welfare Meat quality

Impact on genetic resources Mixed breeds Foreign breeds

Current Situation in ANGR in Oman

Ministry of Agriculture Rumais Station

Genotyping of indigenous breeds Comparison with genetic

background of foreign breeds entered Oman over the past 30 years

Sampling: Blood (300 of each breed) High quality genomic DNA

extracted (standard protocols and kits)

Purification and concentration PCR DNA Analyses

Microsatellite analyses Statistical analyses Allele frequency;

Conservation of native breeds

Breeding Soundness Examination (BSE) Objective

Establish BSE criteria for native Omani breeding sires

Hypothesis Native Omani breeding males would

have the same BSE findings as established for Zebu/Zebu-cross in arid region

Methodology Physical examination Semen collection:

artificial vagina electrical ejaculator

Artificial vagina

Electro ejaculator

Semen visual evaluation

Breeding Soundness Examination (BSE)

Semen Evaluation Sperm mass activity Sperm motility Sperm concentration Sperm morphology Etc. Manual and automated Semen evaluation

Semen evaluation Computer assisted semen evaluation

Semen processing(dilution, extension, storage)

Semen preservation

Semen preservation (straws)

Threats to Indigenous Genetic Resources

• Introduction of exotic animal breeds for:– Slaughter – Production– Bull fighting– AI

• Najdi and Chios sheep• Somali, Indian, Yemeni, etc. sheep and goats • AI:

– A large-scale program using Holstein and Jersey semen

– infusion of exotic genes in local animal herds

• AI History:– AI Unit in Rumais (1990), Salalah

(1993); Nizwa (1994); Ibri (2001); Sohar (2002)

• No follow-up for F1• No performance testing

Omani cattle (Jersey influence)

Omani sheep (Najdi)

Bull fighting (Batina)

What to do?

breed characterization Phenotypic Genetic

National breeding programs: Identification Breeding Societies

National policies Live animal importation and exportation

Artificial Insemination Government policy

Full utilization of local resources Animal & Plant Genetic Resources Center Pooling resources Coordination and collaboration

Conservation In situ (animal stations and labs at SQU, MA, RDC, RDA) Increase herds and flocks Human resources Budget
