dc.descriptionViolation of the boars use regimes leads to deteri- oration in the sperm quality. The percentage of motile sperm in ejaculates collected at seven- and six-day in- tervals between successive selections remains at a rela- tively high and similar level, approximately 72.8–73.9%, and it even slightly increases (up to 75.0 %) at five days intervals. Increasing the frequency of ejaculation selection with an interval of less than five days leads to a decrease in the sperm motility in ejaculates. The index of actively motile sperm in ejaculates collected at one-day intervals was 67.78 %, or by 7.2 2% less than in ejaculates obtained at five-day intervals. This differ- ence was significant at P≤0.05 (Bajena at al., 2016) [1]. The most important characteristic of ejaculate fertiliza- tion is the total number of motile sperm. It determines the number of insemination doses that can be prepared of a single ejaculate (Kondracki et al., 2013) [9]. The data show that with an interval of seven, six or five days between consecutive collections, the number of sperm in the ejaculate remains at a very high level (more than 90 billion motile sperm). Reducing the intervals be- tween consecutive collections to four, three, two and one days leads to a decrease in the number of sperm in the ejaculate by at least 10 billion per day. Similar trends were observed in the case of the number of in- semination doses obtained from one ejaculate.uk_UA
