Breed and Carcass Characteristics on Losses by Bruises and Meat Ph in Beef of Steers and Culling Cows

Abstract: This study aimed to evaluate the effects of the genetic group, maturity, and fatness score of cattle on losses by bruises and final pH value of the carcass of steers and cows. The number of bruises and the final pH value of the carcasses were evaluated as response variables in function of the genetic group, the physiological maturity, and the fatness score. Increases of 174.6 and 159.4% cases of bruises were found when maturity evolved from deciduous to eight teeth for males and females, respectively. The carc… Show more

“…Lower levels of reactivity may also be associated with a reduction in lesions which reflect in bruises on the carcase, resulting in economic loss and a reduction in the quality of the end product (Mendonça et al, 2016(Mendonça et al, , 2019Bethancourt-Garcia et al, 2019a,b). The more-reactive animals generate higher production costs due to greater depreciation of the facilities, the occurrence of bruises, and a loss of quality of the end product, in addition to a greater risk of accidents for employees and for the animals themselves (Mendonça et al, 2017).…”

“…Neste contexto, a condução dos bovinos, da propriedade até o frigorífico, é uma etapa do pré-abate importante, pois muitos fatores como tipo de veículo, densidade, distância, tempo percorrido, condições das estradas, motorista, temperatura, além da associação de dois ou mais destes fatores, são determinantes e causadores de estresse nos animais e contusões nas carcaças, edemas, quedas de pH, alterações na coloração, maciez e qualidade da carne (ROMERO et al, 2013;MENDONÇA, et al, 2017).…”

“…Neste contexto, Coutinho et al 2017avaliaram o efeito do temperamento de zebuínos sobre a atividade inibitória de calpastatina e identificaram a relação desses genótipos com a força de cisalhamento, no qual, animais mais reativos apresentaram maior dureza da carne e menor extensão de amaciamento nas 48 horas do período post-mortem. Neste contexto, Mendonça et al (2017) observaram que fêmeas são mais susceptíveis às alterações no pH final das carcaças, principalmente quando a carcaça é proveniente de animais zebuínos.…”

“…Temperament is associated with stress, and the stress level of cattle also affects the quality of meat. The magnitude of the stress response is affected by individual differences, and this response may negatively influence the efficiency of the immunologic response, reproduction, and development of cattle (MOBERG;MENCH, 2000). Reactive animals may be more susceptible to stress generated by routine handling and consequently, this trait may negatively affect productivity (CAFE et al, 2011).…”

“…Reactive animals may be more susceptible to stress generated by routine handling and consequently, this trait may negatively affect productivity (CAFE et al, 2011). More reactive animals such as zebu cattle also tend to present increased amounts of bruise trim due to injuries acquired during transportation (MENDONÇA et al, 2017).…”
