p The Role of Proteins in Animal Nutrition The Role of Proteins in Animal Nutrition

Proteins are vital elements in animal cells . In the process of digestion , proteins are broken down into amino acids with the use of enzymes such as proteases . These amino acids supply the nitrogen nutritional requirements of the animal body "Cliff Notes . There are two types of amino acids : the essential and non-essential . Essential amino acids cannot be produced by the animals internally , while non-essential amino acids can be produced by the animals with other nitrogen sources

. A with ten of these as essential amino acids and therefore must be included in the diet (Rinehart 1-20

The biologic value of proteins is related to the essential amino acid requirements of the animal . It is also related to the rate of metabolism and digestion of the animal . Biologic value of protein is inversely proportional to the protein requirement in animal diets for the supplementation of amino acids "Merck Veterinary Manual . Complete nutritional requirement of protein is attained when the metabolic need for amino acids and nitrogen is fulfilled . Dietary proteins used for growth and maintenance of animal bodily functions are inefficiently converted to energy when there is insufficient energy from dietary fats and carbohydrates . Improper protein to calorie ratio is likely to cause protein deficiency in animals

Protein requirements differ with species , digestion , age , health and environment . They are expressed as a percentage of diet or as protein-energy...
