Abstract

Under the assumption that milk yield may be reduced in herds with impaired welfare, the present study aimed at investigating whether milk yield could be used as a reliable indicator of welfare. In 125 commercial French dairy herds, the association between the welfare of the herd (evaluated using the Welfare Quality assessment protocol) and cow milk yield was investigated using linear mixed models. Positive associations were identified between milk yield and low aggressions between cows and good emotional state of the herd but there was a negative association with good health assessed through the occurrence of diseases and injuries. These opposite associations resulted in no association with the overall welfare of the herd. Milk yield should not therefore be used as an indicator of overall welfare.

摘要

基于奶牛福利受损的牛群产奶量可能会降低这一假设，本研究旨在调查产奶量是否可作为福利的可靠指标。在125个法国商业奶牛场中，使用线性混合模型研究了牛群福利（采用福利质量评估方案进行评估）与奶牛产奶量之间的关联。产奶量与奶牛间低攻击性以及牛群良好的情绪状态呈正相关，但与通过疾病和损伤发生率评估的良好健康状况呈负相关。这些相反的关联导致与牛群的整体福利无关联。因此，产奶量不应被用作整体福利的指标。
