| Objetivou-se neste estudo avaliar a inclusão de ractopamina e sua associação com as vitaminas antioxidantes C e E em dietas de suínos em terminação durante 28 dias antes do abate sobre o desempenho, as características de carcaça e a qualidade da carne. Quarenta e oito suínos da linhagem Agroceres PIC (24 machos castrados e 24 fêmeas) foram distribuídos em delineamento experimental de blocos casualizados, em esquema fatorial 3x2, com três dietas: controle; controle + 10ppm de ractopamina; controle + complexo (0,05%) de ractopamina com vitaminas antioxidantes (10ppm de ractopamina + 200mg de vitamina E + 100mg de vitamina C kg-1 de ração) e dois gêneros (machos castrados e fêmeas). Foram avaliados o consumo de ração, o ganho de peso e a conversão alimentar... |

| Este trabalho foi desenvolvido com o objetivo de avaliar o desempenho em confinamento de animais puros das raças Tabapuã (T), Bonsmara (B), mestiços ½ Bonsmara + ½ Nelore (B1) e mestiços ½ Bonsmara + ¼ Red Angus + ¼ Nelore (B2). Foram utilizados cinco bovinos castrados de cada grupo genético, com idade média de 22 meses e peso vivo de 394 ± 21 kg, ao início do experimento. A dieta para todos os animais continha silagem de cana-de-açúcar e ração comercial na proporção de 55 e 45% (base seca), respectivamente, com 14,99% de PB e 59,84% de NDT. Os animais foram abatidos quando atingiram escore visual de acabamento de 3, numa escala de 1 = magros a 5 = obesos. Houve efeito significativo dos grupos genéticos sobre o consumo de matéria seca, cujas médias foram... |

| Objetivou-se avaliar o desempenho, as características de carcaça e o peso de órgãos do sistema digestório de suínos submetidos a restrição alimentar. Foram utilizados 40 suínos machos castrados, Landrace × Large White, distribuídos em delineamento de blocos casualisados, com quatro tratamentos, cinco repetições e dois animais por parcela experimental. Como tratamentos, avaliaram-se quatro programas de restrição alimentar: um controle, com alimentação à vontade durante os 86 dias de experimento; e outros três, com restrição de 20% no consumo de ração em relação ao grupo controle, durante 21 dias, a partir dos 30, 50 ou 70 kg de peso corporal (PC). Foram mensurados o consumo diário de ração, o ganho diário de peso e a conversão alimentar. As características... |

| The objective of this study was to evaluate the consequences of low or high stress during pre-slaughter handling of pigs on their carcass and meat quality. Forty-four animals of a commercial lineage, with an average weight of 107.23±5.23 kg, were used. At lairage the animals were randomly divided into two groups, the least and the most stressed. At slaughter, during bleeding, blood samples were collected for later cortisol and lactate tests. Forty-five minutes after slaughter the initial pH of th carcasses was measured and samples of the semitendinosus muscle were collected for R-value calculation. After 24 hours of cooling, the final pH was measured, damage scores were assessed and samples of the longissimus dorsi muscle were collected to evaluate drip... |

| The objective was to evaluate the dietary supplementation of different sources of chromium (inorganic: chromium sulfate and chelated: chromium-methionine) during the finishing period of pigs to obtain improvements in the animal performance, and carcass and meat quality. The statistical design was randomized blocks, where 44 barrows, with an initial weight 60.49±5.12 kg, were divided into four blocks (heavier, heavy, light and lighter) according to initial weight. The experimental diets were isoenergetic and isonutrient, except for the chromium level. The treatments were divided as follows: control (without chromium), control + 200 ppb of inorganic chromium (chromium sulfate), and control + 200 ppb of chelated chromium (chromium-methionine). In the... |

| ABSTRACT A total of 5502 piglets from 435 sows were selected for evaluation of the effect of piglet birthweight and sow parity on mortality rate (MR), growth performance, and carcass traits in pigs. Piglets were distributed into one of eight categories according to their weight (<600, 601-800, 801-1000, 1001-1200, 1201-1400, 1401-1600, 1601-1800, and >1801 g) and sows were classified according to parity (1-5). The maximum MR during lactation (day 0 to day 21) was found in category <600 g, whereas the lowest was observed in categories ≥1401 g. Pigs with greater body weight (BW) at birth were equivalently greater until 59 days of age. Average daily weight gain (ADG) was improved by increasing piglet birthweight between 0 and 21 days as indicated by... |

| The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates. Final weight, weight gain, feed intake and feed conversion were not affected by levels of magnesium supplementation. Hot and cold carcass weights showed linear increasing and quadratic responses, respectively, according to supplementation with magnesium. Carcass measurements such as length, depth, and measures of arm and leg were not affected by supplementation. Depth and width of the longissimus... |
