Resumo: The objective of this study was to evaluate the effects of starting time of feed withdrawal interval preslaughter at the farm (FARM) or at the plant (PLANT) on animal losses, behaviour during loading and lairage, blood parameters (lactate and creatine kinase) and meat quality traits (pH, colour and drip loss) in pigs. A total of 700 pigs was distributed into two treatments groups. The FARM group was fasted for 18 h before the transport plus 6 h before slaughter, including 2 h transport and 4 h lairage, and the PLANT group was fasted for 24 h (considering 2 h transport plus 22 h at lairage), totalizing 24 h of fasting time before slaughter for both groups. The treatments neither influenced transport losses nor blood parameters. However, PLANT pigs had longer fights (P < 0.05) than FARM pigs at lairage and produced darker (P = 0.02) and drier (P = 0.03) loins. Based on these results, it is recommended apply feed withdrawal time before loading, which showed improvements to pigs’ welfare, due to the lower number of fights during lairage at the slaughter plant, and produced better pork quality.

Um total de 700 suínos foi distribuído em dois tratamentos. O grupo FARM fez um jejum de 18 h antes do transporte mais 6 horas antes do abate, incluindo 2 h de transporte e 4 h de período de descanso, e o grupo PLANT fez um jejum de 24 h (considerando 2 h de transporte mais 22 h de período de descanso), totalizando 24 h de tempo jejum antes do abate para os dois grupos. Os tratamentos não influenciaram o as perdas no transporte nem os parâmetros sanguíneos. Contudo, os suínos do grupo PLANT tiveram brigas mais longas (P < 0.05) que os suínos FARM no período de descanso e produziram lombos mais escuros (P = 0.02) e secos (P = 0.03). Baseados nesses resultados, recomenda-se aplicar o tempo de jejum antes do embarque, o que demonstrou melhorias para o bem-estar dos suínos, devido ao menor número de brigas no período de descanso no frigorífico, e produziu melhor qualidade de carne suína.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)CNPq: 131971/2014-0Universidade Estadual Paulista (Unesp)Faucitano, Luigi [UNESP]Costa, Mateus José Rodrigues Paranhos da [UNESP]Universidade Estadual Paulista (Unesp)Dalla Costa, Filipe Antonio [UNESP]2016-03-18T14:00:21Z2016-03-18T14:00:21Z2016-02-25info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfhttp://hdl.handle.net/11449/13631100086710733004102002P07784945129978219enginfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESP2024-06-05T14:28:13Zoai:repositorio.unesp.br:11449/136311Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T22:23:13.111997Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
