Description

A significant reduction in the boar sperm quality during the warmer season of the year is a well-known phenomenon which directly
contributes to a considerable decrease in the fertility of sows artificially inseminated (AI) during the period. The purpose of this study is to determine whether the conventional intracervical AI combined with the synthetic seminal plasma Predil MR-A® can increase the fertility of sows inseminated in warm seasons. The obtained results show that the insemination with Predil MR-A® significantly increases the farrowing rate (82%) in the warm periods of the year in comparison with the control sows (72%). Although an increasing trend in the average number of live born piglets per litter was recorded in the sows inseminated with Predil-MRA®, this increase was not statistically significant (p <0.05) both within or between the observed seasons (ranging from 14.65 to 15.41 piglets per litter ). The obtained results can increase the total efficiency of boar reproductive exploitation as well as the fertility of inseminated sows.
