Resumo: | The objective of this work was to evaluate the influence of lairage periods on the temperament, physiological indicators of stress, and meat quality of beef cattle. Thirty-two castrated Aberdeen Angus x Nellore crossbred steers were distributed into four lairage periods: 12, 18, 24, and 48 hours. The following variables were evaluated: serum levels of the physiological indicators of stress glucose and cortisol (upon arrival at the slaughterhouse, after the lairage period, and at bleeding), animal temperament (movement, resistance to approach, and aggressiveness), and meat quality (final pH, water-holding capacity, color parameters, and tenderness). With a longer lairage period, the temperament score was higher, indicating that the animals were more agitated and resistant to human approach. Serum cortisol and glucose levels correlate positively with animal temperament and negatively with meat quality. At bleeding, an increase was observed in glucose and cortisol levels, respectively, for lairage periods longer than 24 hours and of 12 hours. The lairage of 48 hours reduces meat tenderness and water-holding capacity. |

Trinta e dois novilhos mestiços Aberdeen Angus x Nelore castrados foram distribuídos em quatro tempos de descanso pré-abate: 12, 18, 24 e 48 horas. Foram avaliados as seguintes variáveis: níveis séricos dos indicadores fisiológicos de estresse glicose e cortisol (na chegada dos animais ao matadouro, após o período de descanso e no sangramento), temperamento animal (movimentação, resistência à aproximação e agressividade) e qualidade da carne (valor final para pH, capacidade de retenção de água, parâmetros de coloração e maciez). Com um maior período de descanso pré-abate, a pontuação de temperamento foi mais alta, o que indica que os animais estavam mais agitados e resistentes à aproximação de humanos. Os níveis séricos de cortisol e glicose correlacionam-se positivamente com o temperamento animal e negativamente com a qualidade da carne. No sangramento, observou-se aumento nos níveis de glicose e de cortisol, respectivamente, no tempo de descanso de mais de 24 horas e no de 12 horas. O tempo de descanso de 48 horas reduz a maciez da carne e sua capacidade de retenção de água.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCoordenação de Aperfeiçoamento de Pessoal de Nível SuperiorMoura, Sandra Vieira deSilveira, Isabella Dias BarbosaFerreira, Otoniel Geter LauzMendonça, Fábio SouzaMoreira, Sheilla MadrugaRestle, JoãoGarcia, Javier Alexandre BethancourtVaz, Ricardo Zambarda2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26976Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02349Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e023491678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26976/14921Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26976Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
