Resumo
O objetivo deste trabalho foi avaliar os efeitos do tempo de jejum (9, 12, 15 e 18 horas) dos animais na granja (TJG) e da posição na carroceria do caminhão (PBO) durante o transporte da granja ao frigorífico sobre: a perda de peso corporal (PPC), o peso do estômago cheio (PEC) e vazio (PEV), o peso do conteúdo estomacal (PCE) e o escore de lesão na mucosa esofágica-gástrica (ELG). Foram utilizadas 192 fêmeas, com peso vivo médio de 134,51±11,80kg. No modelo, foram considerados os efeitos de bloco (estação do ano, BL), TJG, PBO e da interação entre BL x TJG. Verificou-se efeito significativo do TJG apenas sobre o peso do conteúdo estomacal. Não se observou efeito significativo da PBO sobre qualquer das variáveis avaliadas. Dos suínos avaliados, 90,3% apresentaram PEC menor que 500 gramas e 8,56% com PEC entre 500 e 800 gramas. A prevalência de suíno com ELG foi baixa (14,97%), sendo que, dos animais com ELG, 13,90% apresentaram lesão de grau 1 e 1,09% eram grau dois. Conclui-se que animais submetidos a jejum na granja de 15 horas apresentam menor peso do conteúdo estomacal ao abate.
The objective of this study was to evaluate the effect of fasting time period (9, 12, 15 and 18 hours) at the farm (TJG) and the pig s position in the lorry s livestock compartment (PBO) during the transport from the farm to the processing plant on: body weight loss (PPC), weight of stomach (full= PEC and empty= PEV), weight of stomach contents (PCE), and incidence of gastric ulcer (ELG). A total of 192 females with average 34.51±11.80kg of body weigh were used. The statistical model considered the effects of: block (season, BL), TJG, PBO and the interaction between BL and TJG. There was a significant effect of TJG only on stomach content. There was no effect of PBO on any of the evaluated variables. A PEC inferior to 500g was observed in 90.3% of the animals, while 8.56% of the pigs presented PEC between 500 and 800g. Incidence of ELG was low (14.97%), and among the ELG animals, 13.90% showed grade 1 lesion, and 1.09% grade two lesion. As a conclusion, pigs submitted to a fasting period of 15 hours have less stomach contents at the processing.
