This trial aimed to assess the qualitative traits of five muscles of 14 Nellore bulls with 450 kg ± 30.7 kg BW, feedlot fed for 60 days. After slaughter and carcass chilling, samples of the Biceps femoris (BF), Longissimus (LD), Gluteus medius (GM), Semitendinosus (ST) and Trapezius thoracis (TT) muscles were collected, vacuum-packed and aged at 0 to 2 ºC for 1, 7 and 14 days and subsequently stored at –20ºC for chemical and quality analysis. The pH, shear force, water holding capacity, cooking losses, meat color and ether extract were evaluated in all aging times. Data were analyzed in a split-plot design using the PROC MIXED procedure of SAS. Aging affected quality traits and chemical properties of the meat, improving aspects, such as tenderness (p <... |

Protein and energy requirements of beef cattle, aged between 4 and 18 months old, on tropical pastures, were estimated. Forty-six Nellore calves (138.3 ± 3.4 kg BW and 90-150 days old), kept on pasture, were distributed in a maintenance group (restricted feeding) or in nutritional plans, receiving a supplements with different amounts of protein and carbohydrate or non-supplemented. The net energy requirement for weight gain (NEg) was obtained by linear regression of logarithm of retained energy as a function of logarithm of empty body weight gain. The net energy requirement for maintenance (NEm) was estimated by the exponential relation between heat production and metabolizable energy intake. Net protein requirement for weight gain (RP) was estimated by... |

ABSTRACT: The aim of this research was to investigate the influence of muscle type on protein oxidation, texture profile (hardness, springiness, cohesiveness and chewiness) and proximate composition of beef from grain-finished Bos indicus (Nellore) cattle in Brazil. The muscles longissimus lumborum (LL) and psoas major (PM) were collected 24 h post mortem from eight (n=8) Nellore bull carcasses, fabricated into five steaks (1.5-cm) and displayed under aerobic conditions for nine days at 4 °C. Proximate composition and texture profile were analyzed on day 0, whereas protein oxidation was analyzed during 9 days of storage. LL exhibited greater (P<0.05) protein concentration than PM steaks, whereas PM demonstrated greater (P<0.05) lipid and ash content... |

The aim of this study was to estimate the components of variance and genetic parameters for the visual scores which constitute the Morphological Evaluation System (MES), such as body structure (S), precocity (P) and musculature (M) in Nellore beef-cattle at the weaning and yearling stages, by using threshold Bayesian models. The information used for this was gleaned from visual scores of 5,407 animals evaluated at the weaning and 2,649 at the yearling stages. The genetic parameters for visual score traits were estimated through two-trait analysis, using the threshold animal model, with Bayesian statistics methodology and MTGSAM (Multiple Trait Gibbs Sampler for Animal Models) threshold software. Heritability estimates for S, P and M were 0.68, 0.65 and... |

O CNPGC realizou um experimento em quatro anos consecutivos (1991-1995). A cada ano, um rebanho de 120 vacas nelores, com bezerro ao pe, foi dividido em dois grupos, levando-se em consideracao as idades e os pesos das vacas e as idades dos bezerros. Durante a estacao de monta (novembro a fevereiro), foram mantidos tres touros, testados andrologicamente, em cada grupo. Em um dos grupos aplicaram-se inseticidas com intervalos que variavam com o principio ativo utilizado, em cada vaca e touro. Os dois grupos foram mantidos em piquetes separados, formados de Brachiaria decumbens, rotacionados a cada catorze dias, com uma taxa de lotacao de 1 UA/ha. As contagens da mosca nas vacas foram realizadas, tambem, a cada catorze dias. As vacas foram pesadas a cada dois... |
