Relations entre les pratiques d'élevage et les caractéristiques de la carcasse et du muscle Longissimus Thoracis chez les bovins allaitants

Abstract : To determine the relationships between breeding practices and carcass characteristics, and between breeding practices and Longissimus Thoracis (LT) muscle characteristics, a data set obtained from 262 cattles was analyzed. In total, 27 variables on breeding practices during the fattening period, the carcass, and LT characteristics, were studied. There were high correlations between the carcass weight and composition (muscles, fat and skeleton) with cattle live weight. Differences appeared between male and female cattle. For male cattle, carcass weight and composition were highly correlated with feeding source during the fattening period whereas no high correlations were observed for female. The lactate dehydrogenase (LDH) activity in LT was highly correlated with breeding practices. LDH activity was negatively correlated with forage amount in the fattening diet and positively with concentrate amount. Furthermore, LDH activity was correlated with the duration of fattening period only for male cattle.
