Existe-t-il une relation entre bien-être et performances de reproduction chez la vache laitière ?

Abstract : This study was conducted in the 113 herds evaluated by the Welfare Quality® Protocol during the 2010-2011 winter and described by De Boyer des Roches et al. (2012). First or second AI (Artificial Insemination) performed over a period of 40 days before or after welfare evaluation were taken into account. Two parameters were used to evaluate reproductive performance: calving to first AI interval and conception rate (CR, non return rate 90 days after AI). Performances were compared between cows bred in the herds with a low welfare score (30% lower scores) to the performances of the other animals. The fixed effects of breed (Prim’Holstein vs Montbeliarde), crossbreeding (breed of the bull different from the breed of the inseminated cow or not), lactation rank (primiparous vs multiparous), month of calving, month of AI, calving to AI interval, rank of AI (1 or 2), mean and maximum milk production during the three first months of lactation and random herd effect were taken into account. Variation factors of CR were investigated on a sample of 1428 AI (1155 AI1 and 273 AI2). CR (57.8%) was significantly related to rank of AI and breed but not to welfare score (58.2% for the animals bred in the low scored herds and 56.8% for the cows bred in the high scored herds, p=0.06). Calving to first AI interval (81.6±27.7 days, mean±sd) was related to breed, month of AI and herd welfare score. It was shorter for the cows bred in the highest scored herds (78.9±1.6 vs 85.6±2.4 days; lsmeans±sem; p<0.05). Among the four welfare principles (good feeding, good housing, good health and appropriate behavior), only good feeding and good health were associated to calving to first AI interval. This study shows for the first time to our knowledge, a relationship between reproductive performance and welfare evaluation in dairy cows.
