  2. 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.

  3. Minerals • TBA

  4. Minerals • TBA

  5. Helpful Abbreviations • Abbreviations • Y = Young • C = Cattle • Ch = Chickens • H = Humans • S = Swine • Sh = Sheep • T = Turkeys • A = Adults

  6. 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)

  7. 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

  8. Minerals • Micro (Trace) minerals • Manganese: • Lameness and shortening and bowing of the legs, enlarged joints (Y); perosis (YCh and YT); reduced egg shell thickness (AChand 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)
