热应激对瘤胃微生物的影响及其与奶牛生产性能的关系
Effects of Heat Stress on Rumen Microbiota and Its Relationship with Performance of Dairy Cows
摘要
Abstract
Rumen microbial diversity and richness are closely related to the nutrient metabolic efficiency and performance of ruminants. Dairy cows have physiological characteristics of resistance to cold and sensitivity to heat, which determine their physiological health and performance are easily affected by heat stress. Heat stress may affect colonization of the rumen microbiota by damaging rumen epithelial integrity and homeostasis, there?by reducing the feed efficiency and performance of dairy cows, causing serious economic losses to dairy indus?try. In this review, the mechanism of heat stress affecting rumen microbiota was discussed from the aspects of rumen epithelial morphology, rumen temperature and rumen fluid pH, and the relationship between rumen mi?crobiota and feed efficiency, milk yield and milk composition was also discussed. This review could provide a theoretical reference for further understanding of the effect of heat stress on rumen microbiota and its relation?ship with performance of dairy cows.[ Chinese Journal of Animal Nutrition, 2019, 31(10) :4458?4463]关键词
