Preventive Supplementation of Vitamin E and Selenium as a Factor in Improving the Success Rate of Embryo Transfer in Cattle

Abstract The effects of stress on processes in the body are becoming an increasingly relevant research subject. reproductive ability bovine animals largely depends these effects, whilst embryo transfer is being used as a reproduction method. In this study, we established differences implantation heifers that were treated (N=17) with selenium (Se) and vitamins AD 3 E, non-treated heifers. Upon transfer, took blood samples from both groups total antioxidant status (TAS) value to analyze presence reactive oxygen species (ROS), levels non-esterified fatty acids (NEFA) vitamin E Se plasma. able demonstrate preventive measures form supplementation Se, mitigate oxidative stress, strengthen organism improve dynamic relationship between free radicals antioxidants, energy cattle, positively impact parameters increase success rate transfer. difference number successful implantations control group was statistically significant, 64.7% pregnant after giving birth healthy calves. group, 41.2%. antioxidants combination proved be good method for strengthening defense effective mean clinical approach improving fertility parameters.
