| O experimento teve por objetivo avaliar o efeito do sistema de criação e da época do ano, sobre o desempenho e qualidade da carne de frangos de corte. Foram estudadas 524.000 aves da linhagem comercial Cobb 500, distribuídas em três galpões com diferentes sistemas de automatização, durante as quatro estações do ano. O delineamento foi inteiramente casualizado, com esquema fatorial 3 x 4 (tipo de galpão x época do ano). Foram utilizadas rações do sistema integrado, cama de palha de arroz, e as aves foram abatidas em um frigorífico aos 43 dias de idade. Foram avaliados os dados de desempenho (consumo de ração, ganho de peso diário, conversão alimentar e mortalidade), com dados fornecidos pelo sistema integrado. Também, foram avaliados os defeitos nas... |

| ABSTRACT The present study was carried out to investigate the influence of freezing-thawing cycles (0, 2, 4 and 6) on lipid oxidation and myowater contents and distribution. Nine replicates of chicken breast meat samples were used for each cycle. Lipid oxidation was determined by measuring peroxide value, and malondialdehyde (MDA) concentrations, which reflect thiobarbituric acid reactive substance (TBARS). Color was determined with a digital colorimeter. Muscle moisture contents were determined by drip loss and thawing loss, water holding capacity, and nuclear magnetic resonance (NMR). The results showed that, as the number of freeze-thaw cycles increased, meat redness decreased and MDA and peroxide values increased. Drip loss and thawing loss tended to... |

| Presently there is a growing interest in the production and marketing of wild boar meat, and to attend a differentiated consumer demand the quality attributes of this product should be well established. To characterize the quality of wild boar meat in comparison to commercial pork, post mortem changes in the longissimus dorsi and semimembranosus muscles were determined by pH and temperature decline, and color (CIE L*a*b*) measurements. Water holding capacity (WHC) was determined by the compression method and the exudate loss (EL) by the drip loss test. Decline in longissimus dorsi muscle pH of wild boar was gradual and in the pork it was faster and more extensive. Temperature differences were observed in some post mortem times, and the lowest values were... |

| Abstract: The objective of this work was to develop and evaluate prediction equations, based on measurements obtained on the slaughter line, for carcass classification according to the degree of exudation and the content of marbling. A total of 747 pig carcasses originated from 27 producers were randomly selected on the slaughter line at two slaughterhouses, constituting representative samples from each one. Hot carcass weight, loin depth, back fat thickness, and pH and temperature 45 min after slaughter were used to generate the equations. The carcasses were classified as normal or exudative for drip loss of loin and ham, and as acceptable or undesirable for marbling content. For drip loss of loin and ham, respectively, the overall correct classification... |

| Thirty eight pigs born from same sow were divided into 2 group，and fed with or without cheese whey. Pigs were slaughtered after 137-172 days when the live weight was nearly 110kg. Samples of M. longissimus thoracis were analyzed for physicochemical properties. There was no significant difference in the pH，water content and colour appearance in pork between the whey and control group. Crude protein content of the whey group (21.7%) was significantly lower than that of the control (22.6%). Drip loss was measured at 1，5 and 10 days after slaughter，and the drip loss measured at 10 days was significantly lower in the whey group (25.4%) than that of the control (27.1%). Cooking loss was measured at 5 days after slaughter，was significantly lower in the whey group... |
