Research Progress of Exogenous Vitamin E and Selenium Regulating Semen Quality in Animals
Semen quality is an important index to measure the breeding value of male animals(poultry).Excessive reactive oxygen species(ROS)will be produced during the stress state of male animals(poultry)or semen freeze-thaw process,and when the antioxidant system of the animal or sperm itself cannot balance the excessive ROS,it is easily lead to the decline of semen quality.Vitamin E and selenium are two common antioxidants,and their moderate addition to animal diets or semen dilutions can alleviate the deterioration of semen quality caused by stress in males(poultry).In this paper,the application effect of vitamin E and selenium in regulating the semen quality of male animals(poultry)and the mechanism of their synergistic effect are reviewed,to guide production practice.
