The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

This study was carried out to determine the apparent digestibility coefficients (ADC) of amino acids for corn, wheat bran, soybean meal and fish meal in Nile tilapia (Oreochromis niloticus), juveniles (25.24 ± 3.88 g), fed purified pelletized reference diet containing 33.78% crude protein and 0.10% of chromic oxide (indicator). The average ADC of amino acids were: 88.31; 77.40; 91.78 and 82.58% for corn, wheat meal, soybean meal and fish meal, respectively. Althought results suggest that the protein ADC value is indicative of amino acids ADC, there was variability in individual amino acid digestibility within and among the tested feeds. The results suggest that use of digestible values of amino acids should be use for more accurate and economical feed formulation.
