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.

ABSTRACT We used five nonlinear models to calculate the weight gain of rainbow trout (122.11±15.6 g) during the final grow-out phase of 98 days under three different feed types (two commercials diets, A and B, and one experimental diet, C) in triplicate groups. We fitted the von Bertalanffy growth function with allometric and isometric scaling coefficient, Gompertz, Logistic, and Brody functions to weight (g) at age data of 900 fish, distributed in nine tanks. The equations were fitted to the […]

Weights at birth, at weaning and monthly from 8 to 19 months of age of the 11 genotype identified by combination of polymorphic RFLP’s of the genes kappa-casein-HinfI (CSN3): AA and AB, growth hormone-AluI (GH): LL and LV, and b-lactoglobulin-HaeIII (LGB): AA, AB and BB (G1=AALLAA, G2=AALLAB, G3=AALLBB, G4=AALVAB, G5=AALVBB, G6=ABLLAA, G7=ABLLAB, G8=ABLLBB, G9=ABLVAA, G10=ABLVAB e G11=ABLVBB) were used. Data were obtained from three genetic groups: ½Canchim-Nelore (CN), ½Angus-Nelore (AN) and ½Simmental-Nelore (SN), born in 1998 and 1999 in Southeast […]

Records of the weights at birth, weaning and monthly from 8 to 19 months of age from three genetic groups: ½Canchim-Nellore (CN), ½Angus-Nellore (AN) e ½Simmental-Nellore (SN), born in 1998 and 1999 in Southeast Brazil, were used to fit a Logistic nonlinear model that included the fixed effects of the contemporary group and genotype of the genes kappa-casein-HinfI (CSN3): AA and AB, growth hormone-AluI (GH): LL and LV, and b-lactoglobulin-HaeIII (LGB): AA, AB and BB, to examine the effect of […]
