DEFINITION OF OPTIMUM TIME OF INSEMINATION OF SOWS AFTER THE BOARS RECEIVED THE PREPARATION SIDNOKARB
Many factors influence on the the reproductive function of boars. First of all, this is their conditions of feeding and keeping, as well as climate or seasonal factors, which significantly reduces their reproductive function due to stressful situations. In the period of stressful situations there are not only changes in the hormonal status of the organism of boars but also in their sexual behavior and this has an effect on the central nervous system. In this study there is the solution for the problem of the search of ways of stimulation of the Central nervous system in the States of the boars-producers, which are caused by the extremely low atmospheric pressure. Therefore, the aim of the research was to determine the optimal time of insemination of sows with influence of the preparation on the body of boars, stimulating the Central nervous system and easying asthenic syndrome. For these purposes was used drug Sidnokarb, which was fed to boars 30, 60 and 90 minutes before the taking of sperm for insemination and breeding sows. The studies have determined, that feeding of the preparation to boars-producers changed the time of onset of sexual reflexes of boars, especially after 60 and 90 minutes after use. Clinical indicators of boars were at a normal level already in 60 minutes after feeding, qualitative and quantitative indicators of sperm were high and over 60 and 90 minutes remained practically at the same level. Breeding efficiency of sows and their prolificacy by groups differed slightly, but in the experimental groups were slightly higher than in the control. Thus, we can draw the following conclusions: introduction to the diet of pigs preparation Sidnokarb does not degrade the performance of the reproduction of the sows, and due to improvement of sperm there is even some improvement. However, the main effect of action of the preparation is noted due to removal of the boars of asthenic syndrome, improvement of indicators of sexual reflex and additional obtaining of doses of sperm. The best time of insemination is the time in 60 minutes after feeding of the praparation.
