摘要
热应激不仅导致奶牛产奶量与牛奶品质下降,也深度影响奶牛生产性能,给产业发展造成损失.本文对奶牛热应激现状、评估方法、对泌乳性能影响、缓解措施进行分析.提出通过遗传改良、物理降温、饲养管理、调整营养等方式缓解奶牛热应激,提高泌乳性能、养殖综合效益的建议.
Abstract
Heat stress not only leads to a decline in milk yield and milk quality of dairy cows,but also profoundly affects their production performance,resulting in losses to the industry.This paper analyzed the current status of heat stress in dairy cows,its assessment methods,its impact on lactation performance,and mitigation measures.Suggestions were provided to alleviate heat stress in dairy cows through genetic improvement,physical cooling,feeding management,and nutritional adjustment,with the aim of improving lactation performance and overall breeding efficiency.
