The differences in semen quality and antioxidant activity were compared by adding culture media with different concentrations of β-carotene and vitamin A. The results showed that adding an appropriate amount of β-carotene and vitamin A can improve the vitality of bovine semen, reduce abnormal rates and oxidative damage, but excessive addition may reduce semen quality. Therefore, an appropriate amount should be added according to the actual situation.Keywords: β-Carotene; Vitamin A; Bovine Semen; Quality; Antioxidant Activity
