Good quality animal nutrition is essential, as it affects animal health and consequently food safety
RESULT ON POOR ANIMAL NUTRTION:
Poor feeding practices can lead to diseases such as nutritional secondary hyperparathyroidism, a condition involving the muscles and bones of dogs that is associated with an all-meat diet. Large, rapidly growing puppies that consume too many calories and too much calcium can develop hypertrophic osteodystrophy, a disease resulting in lameness. Cats need sufficient amounts of an essential amino acid called taurine in their diets. Without it, they may develop eye problems. Not enough iodine intake can cause a goiter, or enlargement of the thyroid gland, in cows, horses, and other animals.

MINERALS a micronutrient ; required by animals are phosphorus, sulfur, potassium, magnesium, and zinc. Animals usually obtain these minerals when they consume plants.
MACRONUTRIENTS - These are nutrients that are needed in large quantities.
MICRONUTRIENTS - These are nutrients that is essential in minute amounts for the proper growth and metabolism of a living organism.

Nutritional Requirements (pages 767-770)
Animals need a variety of nutrients to meet their basic needs. These nutrients include fats and carbohydrates that provide energy, proteins that furnish amino acids, vitamins that serve as co-factors for enzymes and perform other functions, ions required for water balance and for nerve and muscle function, and
