The objective of this study was to determine the true ileal digestibility coefficients of the protein and digestible amino acid of a yeast protein extract using two techniques – diet without protein (DIP) and diet with enzime-hydrolysed casein (CHE) – for the determination of protein amino acid and nitrogen losses. Twelve half-breed barrows were used, with average weight of 35 kg, previously submitted to a surgery for “T” simple cannula implantation. A completely randomized experimental design with three treatments, four […]
