Essential Minerals for Animal Health

Essential Minerals for Animal Health

• Animals require minerals for proper growth and function.
• More than 18 essential minerals exist.
• Minerals are classified into macrominerals and microminerals.

Macrominerals

• Macrominerals are required in significant quantities (percentage).
• Key macrominerals include calcium (Ca), phosphorus (P), potassium (K), sodium (Na), magnesium (Mg), and chlorine (Cl).

Calcium (Ca)

• Crucial for skeletal and tooth development.
• Vitamin D regulates calcium absorption.
• Deficiencies lead to bone loss and fractures (e.g., in diets lacking calcium-rich foods or consisting solely of meat).
• Excessive supplementation can cause skeletal malformations (e.g., skeletal wobblers).

Phosphorus (P)

• Essential for bones, teeth, DNA, and RNA.
• Found in meat, eggs, and dairy products.

Magnesium (Mg)

• Supports metabolism of carbohydrates, lipids, and protein synthesis.
• Deficiencies result in weakness and ataxia (seizures).
• Excesses can lead to struvite crystals and stones.
• Sources include bone meal, oilseeds, unrefined grains, and fiber (e.g., wheat, bran, beet pulp).

Sodium Chloride (NaCl)

• Vital electrolytes for maintaining balance and nerve function.
• Found in fish, eggs, milk, protein sources, and poultry byproducts.
• Deficiencies can disrupt neurological function, digestion, and reproduction.

Microminerals

• Microminerals are required in smaller amounts (parts per million or milligrams per kilogram).
• Key microminerals include iron (Fe), copper (Cu), zinc (Zn), iodine (I), manganese (Mn), and selenium (Se).

Iron (Fe)

• Essential for red blood cells (RBCs) and oxygen transport.
• Deficiencies cause hypochromic microcytic anemia.
• Sources include organ meats, beet pulp, and peanut hulls.

Zinc (Zn)

• Crucial for metabolism of carbohydrates, lipids, proteins, skin growth, and development.
• Deficiencies can occur from high cereal diets.
• Ingesting pennies is a potential source of excess zinc.
• Sources include meats and fibers.

Copper (Cu)

• Necessary for iron absorption, skeletal development, and coat color.
• Deficiencies can result in anemia and impaired skeletal growth.
• Colored coat pigmentation is affected by copper deficiencies.
• Sources include legumes, whole grains, nuts, shellfish, and seeds.

Selenium (Se)

• Protects cell membranes.
• No deficiency or toxicity cases have been reported.
• Sources include fish, eggs, and liver.

Iodine (I)

• Essential element for thyroid hormone synthesis, thermoregulation, growth, muscle function, reproduction..
• Iodine deficiency causes goiter (enlarged thyroid gland).
• Sources include fish, eggs, iodized salt, and poultry byproducts.

Chromium (Cr)

• Supports carbohydrate and lipid metabolism and helps regulate blood glucose levels (enhances insulin activity).
• Sources include brewer's yeast and whole grains.
