В племрепродукторе поддерживается постоянная температура в пределах 18,0…21,0 °С. Условия теплового стресса (22,08±4,28…25,02±5,02 ℃) возникли в результате сбоя системы кондиционирования в помещениях промышленного свинокомплекса и продолжались в течение шести недель. Наибольший негативный эффект проявился у свиноматок, подвергшихся максимальному тепловому стрессу во время осеменения (II группа) – у них наблюдали снижение оплодотворяемости по сравнению с I группой на 4,6 %, увеличение количества слаборазвитых поросят – на 2,5 и 6,1 % по отношению к I и III группам, мертворожденных – соответственно на 4,3 и 4, 1 %; количество мумифицированных поросят было больше по отношению к III группе. У свиноматок, подвергшихся воздействию высоких температур до осеменения (III группа), отмечено увеличение слаборазвитых поросят по отношению к I группе на 3,7 %. У свиноматок, осемененных до теплового воздействия (I группа), негативных последствий на репродуктивные показатели не обнаружено.</p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to the study of reproductive qualities of sows subjected to heat stress after insemination during the period of insemination and before insemination (I, II and III groups, respectively). The breeding reproducer maintains a constant temperature in the range of 18.0...21.0 °C. Heat stress conditions (22.08±4.28…25.02±5.02 ℃) arose as a result of a malfunction in the air conditioning system in the premises of an industrial pig complex and lasted for six weeks. The greatest negative effect was observed in sows subjected to maximum heat stress during insemination (II group) – they had a decrease in fertility compared to the I group by 4.6 %, an increase in the number of underdeveloped piglets – by 2.5 and 6.1 % compared to the I and III groups, stillborns – by 4.3 and 4.1 %, respectively; the number of mummified piglets was also higher compared to the III group. In sows exposed to high temperatures before insemination (III group), there was an increase in underdeveloped piglets compared to the I group by 3.7 %. In sows inseminated before exposure to heat (I group), no negative consequences were found for their reproductive indicators.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оплодотворяемость</kwd><kwd>многоплодие</kwd><kwd>поросята</kwd><kwd>осеменение</kwd><kwd>тепловое воздействие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>conception rate</kwd><kwd>prolificacy</kwd><kwd>piglets</kwd><kwd>insemination</kwd><kwd>thermal effects</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Pollman D.
