Abstract(s)
O estudo realizou-se em vinte sessões, e teve como objetivo a análise do efeito de alguns parâmetros
de bem-estar animal no indicador da qualidade da carne, o pH no músculo Longissimus dorsi de
suíno, aos 240 minutos post mortem. Estudaram-se os parâmetros de bem-estar animal: duração do
transporte e densidade animal no mesmo; duração do tempo de jejum e do tempo de espera no
matadouro; densidade animal na abegoaria; vocalização; caraterísticas do atordoamento; o período
de tempo entre o atordoamento e sangria; e a temperatura muscular no ld. Devido ao facto de
alguns dos resultados não possibilitarem o estabelecimento de uma relação entre todos os
parâmetros analisados, concluiu-se que seria necessário que o estudo abrangesse um maior número
de amostragens. Apesar do número reduzido de casos, o presente estudo permitiu verificar que
houve tendência para fatores relativos ao bem-estar animal influenciarem o valor do pH.
This study was conducted in twenty sessions, and aimed to analyze the effect of some parameters of animal welfare in an indicator of meat quality in pigs, pH measured in Longissimus dorsi 240 minutes post mortem. In parameters related to animal welfare, we studied: the duration of transport and stocking density; duration of fasting; waiting time and stocking density in lairage; vocalization; electrical stunning parameters and the time between stunning and bleeding; and muscular temperature. Given some of the results did not allow the establishment of relationships between all parameters studied, it was concluded that the study would need to cover a larger number of samples. Although we studied a small number of cases, this study showed that there is a tendency for factors associated with animal welfare to influence pH.
