RESUMO A presente pesquisa foi realizada com o objetivo de avaliar os níveis de colesterol, extrato etéreo, perfil de ácidos graxos e o índice aterogênico e trombogênico da gordura intramuscular de suínos machos imunocastrados em relação às fêmeas e aos machos castrados cirurgicamente. Utilizaram-se 45 animais, com peso inicial de 25,2±2,8kg, distribuídos em delineamento inteiramente ao acaso, com três tratamentos (machos castrados, machos e fêmeas imunocastrados) e três repetições de cinco animais cada. Os animais foram abatidos a 90,3±2,7kg. As amostras de Longissimus dorsi foram coletadas, liofilizadas e analisadas quanto ao perfil de ácidos gordos, colesterol e extrato etéreo. Não foram observadas diferenças (P>0,05) para nenhuma das variáveis... |

Abstract The effects of immunocastration and ractopamine in the diet on the belly quality were investigated from two crossbred pigs under different conditions of production, diet, management, and slaughter arranged in factorial design using two levels of addition of ractopamine in the diet, 0 and 7.5 ppm, and three genders (gilts, immunocastrated and barrows). The quality of bellies were analyzed for chemical composition, pH, meat and fat color, backfat thickness and fatty acid profile of the fat. The addition of ractopamine showed no significant influence on pH, color and chemical composition in two crossbred pigs. The immunocastrated had thicker belly backfat compared to the bellies of the gilts. The contents of fatty acids polyunsaturated, linoleic,... |

ABSTRACT The objective of this study was to evaluate the behavior of immunocastrated male pigs compared with females and castrated males during the period before and after full immunization. A total of 30 animals were divided into three treatments, with ten animals in each (females, barrows, and immunocastrated males). The experiment was divided into three periods: 70 to 80 days of age (period 1), 81 to 110 days of age (period 2), and 111 to 140 days of age (period 3). The behavior of animals during these stages was evaluated. Immunocastrated males showed a higher rate of aggressive and sexual behavior during period 2, which decreased after the second vaccine dose. Both barrows and immunocastrated males presented high locomotion in period 1, reducing the... |
