Comparative effects of vegetarian diet and rendered animal by-product on the chicken gut health.

ABSTRACT: Rendered animal proteins and fats can provide vital nutrients for poultry at affordable prices. With growing interest in reintroducing rendered animal by-products into poultry diets, this study investigated the effects of replacing a portion of soybean meal and vegetable fat with rendered animal proteins and fats in a standard vegetarian chicken diet.

Five diet treatments were formulated to be isocaloric and isonitrogenous and balanced for amino acids, including a standard vegetarian control diet and four diets containing rendered animal by-products.
