摘要:

7 diets were prepared containing as their only source of protein one of the following feeds: fish meal, casein, hydrolyzed feather meal, grieves, wheat gluten, maize gluten, soybean meal. Crystalline amino acids were supplemented except in cases of fish meal and casein to prevent specific amino acid deficiencies. Concentrations of N × 6.25 ranged between 436 and 457 g/kg dry matter (DM). Cr2O3was added to each diet for indirect determination of digestibilites.
