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 effect of halothane genotypes (heterozygous and dominant homozygous) and intensive rearing systems (indoor, wood shavings bedding and outdoor) on pork quality were determinated. Ninety six castrated male pigs were used for the trial. Identification of the halothane genotype was determined in blood samples using the DNA-test, based on the polymerase chain reaction (PCR) amplification of the critical region of the ryanodine receptor and subsequent restricion of the amplifield fragment by the restriction fragment lengh polymorfism (RFLP) technique. The pH […]

The objective of this study was to evaluate the effect of the halothane genotypes (heterozygous and dominant homozygous) and intensive rearing systems (indoor, wood shavings bedding and outdoor) on growth performance, carcass and meat yield. Ninety six castrated male pigs were used for the trial. Identification of the halothane genotype was determined in blood samples using the DNA-test, based on the polymerase chain reaction (PCR) for amplification of the critical region of the ryanodine receptor and subsequent restriction of the […]

The aim of this research work was to evaluate the effect of the halothane gene on the quality characteristics of pork. Commercial hybrid pork carcasses (151) were used for the trial, 93 with normal halothane genotype (HalNN), 51 heterozygous genotype (HalNn) and 7 homozigous recessive genotype (Halnn). The measured attributes were carcass weight, muscle temperature at 45 minutes and pH at 45 minutes and 24 hours after the slaughter at the Longissimus dorsi muscle and color. Identification of the halothane […]

The swine stress gene (hal gene) in recessive homozygosis (nn) is associated with the occurrence of the Porcine Stress Syndrome (PSS) and with the occurrence of pale, soft and exudative pork (PSE). In heterozygosis (Nn) it is related to low quality of carcass, but higher carcass weight. This study has characterized the genotype of hal gene by DNA-testing, obtained by alkaline extraction from a single hair root, in a sample of 160 swines. These animals were slaughtered and carcass traits […]
