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.

The objective of this study was to propose and discuss a method to compare the feed into product conversion between two experimental groups of beef cattle based on regression techniques. The mathematical and statistical procedures were developed using a databank of dry matter intake and average daily gain of 380 purebred or crossbred zebu animals on the BR-CORTE nutritional system database. Two groups were selected from the databank and were formed by Nellore (n = 156) or F1 European × […]

The objective of this study was to propose and discuss a method to evaluate the efficiency of feed conversion into product from beef cattle based on regression techniques. The mathematical and statistical procedures were developed using a database composed of measurements of dry matter intake and average daily gain of 380 pure or crossbred zebu animals in 15 different experiments in the database from the BR-CORTE nutritional system. Two approaches were presented, based on linear and non-linear regression, with average […]
