Abstract

Endotoxin (also called lipopolysaccharide) is a split product of cell walls of Gram-negative bacteria. In dairy production, especially in large-scale dairy farms, feeding high-concentrate diets, unsatisfactory environmental hygiene, severe heat stress and so on can result in an increased amount of endotoxin in cow's body. Endotoxin can cause systemic inflammation and metabolic changes, as well as reduce reproductive performance of dairy cows. This article focused on endotoxin source and the effects of it on sex hormones, germ cells, embryos and uterus of dairy cows and discussed the reproductive performance mechanisms in order to provide references for improving reproductive performance of dairy cows.
