Learning Targets
• Identify the functions of various macro and micro minerals in animal nutrition.
• Describe the symptoms of an animal’s body given a toxicity or deficiency of a mineral.
Minerals• TBA
Minerals• TBA
Helpful Abbreviat ions
• Abbreviations– Y = Young– C = Cattle– Ch = Chickens– H = Humans– S = Swine– Sh = Sheep– T = Turkeys– A = Adults
Minerals• Macro minerals
– Calcium: • Rickets, osteoporosis, poor growth (A); muscle cramps, convulsions (H)
– Phosphorus: • Rickets (Y), osteoporosis (A), anorexia, pica, low fertility
– Magnesium: • anorexia, poor productivity, tetany (A); weak crooked legs (S)
– Potassium: • Muscular weakness, paralysis (H); abnormal electrocardiograms, unsteady gait, weakness,
pica (A)– Sodium:
• Anorexia, muscle cramps, mental apathy (H); dehydrated appearance, craving for salt, weight loss (A)
– Chlorine:• Depressed growth
– Sulfur:• Reduced gain or loss of weight (C, Sh); loss of wool (Sh)
Minerals• Micro (Trace) minerals
– Chromium:• Impaired ability to metabolize glucose
– Cobalt:• Primarily ruminants; symptoms similar to cobalamin emaciation anemia,
fatty degeneration of the liver– Copper:
• Anemia; when coupled with high Mo and/or sulfate, swayback or enzootic neonatal ataxia, loss of pigment in hair or wool (C and Sh); bone abnormalities, cardiovascular lesions, reduced egg production reproductive failure
– Flourine:• Excessive tooth decay (H)
– Iron:• Anemia and associated poor productivity, very common in young pigs
Minerals• Micro (Trace) minerals
– Manganese:• Lameness and shortening and bowing of the legs, enlarged joints (Y); perosis (YCh
and YT); reduced egg shell thickness (ACh and T); weakness, poor sense of balance; crooked calf disease (C), poor fertility (C)
– Molybdenum• Reduced growth rates (not very common)
– Nickel:• Prenatal mortality, unthriftiness, decreased growth rate (YCh, T, YS)
– Selenium:• Nutritional muscular dystrophy (Y), exudative diathesis (YCh, T); liver necrosis (YS);
heart failure (YC); retained placenta (AC)– Zinc:
• Poor growth, anorexia, parakeratotic lesions on head, neck, belly and legs (C, Sh, S); perosis, abnormal feathering (YCh, T); poor testicular development, slow wound healing (H, other species)
