Investigations of the Influence of Vitaton (preparation with beta-carotene biomass) on the Breeding Boars Sperm Quality, Reproductive Ability, Clinical State, and Metabolism of the Breeding Sows, Producing Capacity, and Safety of Piglets NATIONAL AGRARIAN UNIVERSITY Kiev, Ukraine 1. Feeding of the breeding boars of the Large White Breed with Vitaton in a quantity of 0.8 g per head daily within the mixed feeds during 62 days does not affect their clinical state, metabolism and resistance. 2. Introduction of Vitaton into the mixed feeds composition for the breeding boars promotes the increase of a survival rate of the spermiums by 18.6-27.9% at the thermoresistant sample of the native sperm at a temperature of 38 0C during 3-9 hours. 3. Feeding the breeding boars with Vitaton within the mixed feeds increased the impregnation rate of the sows after the second, third, fifth, and seventh farrows by 7.5% as an average. 4. Feeding of the sows with Vitaton within the mixed feeds during the pregnancy and the milking period does not affect the hematologic parameters, decreases the urea level in the blood plasma by 67%, increases total lipids by 1.3 times. 5. It was established that the quantity of beta-carotene from the total sum of carotenoids of the sows’ blood plasma constitutes 13% with increasing to 16% during feeding with Vitaton. 6. Introduction of Vitaton into the feeds for lactating sows promotes the increase in their blood of the relative quantity of T-lymphocytes by 4.3%, T-suppressors – by 2 times, T-active suppressors – by 3.4%, phagocytic activity of neutrophilles using a test-microorganism Bl. tirspora – 3.4 %, and phagocytic index – by 1% along with the decrease of the relative quantity of T-0 lymphocytes. 7. The impregnation of the sows with the sperm of the breeding board fed with Vitaton within the mixed feeds increases the multiple pregnancy in them on average by 2 heads per the farrow. 8. Feeding the sows with Vitaton within the mixed feeds during the whole period of the pregnancy increased the multiple pregnancy along with the decrease in piglets’ weight at birth on average by 16.8% in comparison with the control. 9. Feeding of the sows with Vitaton during the whole period of the pregnancy and the milking period increased the live weight at breaking by 9.9% in comparison with the control.
