Boar Sperm Survival Ability in Distinctors of Differently Produced Distilled Water

Abstract

Testing and comparative evaluation of germ cells in boars of Landrace breed of different genotypes on qualitative and quantitative indicators, for further use in diluents of different distilled water, is carried out. Studies have shown that the quantitative and qualitative indicators of sperm production of French boars had the highest ejaculate volume and sperm count among other boars. Boars of domestic selection had the highest concentration of sperms, and boars of English selection prevailed in terms of motility. The results of research show that among the tested ejaculates the best sperm at a dilution of 1: 1 were found in boars of English Landrace pig breed, the absolute survival rate of which was (Sa) - 732.4 um. from according to the degree of rarefaction 1: 2 - 1: 3, the highest rate had ejaculates of boars of French selection, the studied indicator of which was (Sa) - 720.9 (Sa) - 708.8 um. from in accordance. The use of distilled water of foreign production has improved the survival rates of boar semen compared to distilled water of domestic production, which is produced directly at the artificial insemination point of the farm. Thus, according to this indicator, the semen of domestic boars lived 3.7 hours or 3.4% less than the semen of French boars and 8.8 hours or 5.3 % less than the semen of English boars. The thinning of semen in other degrees did not reveal a probable difference between boars. Analysis of these studies shows that the semen of boars of English selection prevailed on the studied indicator of semen of other boars when used in diluents of water of foreign, domestic and local production (obtained at the point of artificial insemination of the farm).

Вони вивчають вплив абіотичних факторів на біологічні характеристики статевих клітин кнурів; стимулюючий ефект феромону у різні пори року на статеву функцію свиноматок, рівень заплідненості та багатоплідності свиноматок залежно від кратності осіменіння у різні пори року, вплив вітаміногормональних схем стимуляції ремонтних свинок на їх репродуктивну функцію [36,37]. Всі ці дослідження спрямовано на підвищення ефективності методу штучного осіменіння свиней в Україні.…”
