potrophic female piglets before sucking colostrum have sterile microflora in genital tracts. <...> At the same time hypotrophic female piglets with respect to normotrophic female piglets after sucking colostrum more rarely had in their genital tracts: lactobacteria - by 25%, bifidus bacteria – by 47%; but they more often had enterobacteria – by 25%, including Escherichia lactose positive – by 41,7%, enterococcus – by 8,3%, Staphylococcus aureus – by 16,7%. <...> The analysis of the represented data showed that newborn female piglets with hypotrophy syndrome and normotrophics under practically the same number of species in biocenosis had some qualitative and quantitative differences, which proved vaginal biotope formation disorders and colonization resistance decrease in newborn female piglets with hypotrophy. <...> Vaginal biotope of 3-4-week female piglets according to its properties was close to vaginal ecosystem of healthy sows. <...> The female piglets before sexual maturity onset in their sexual tract microflora had some changes, characterized by the absence of pathogenic bacteria forms, greater saturation of vaginal biotope with indigenous microflora and lesser number of transient bacteria, that in the future created favorable conditions for their successful insemination. <...> : Аутофлора человека в норме и патологии и ее коррекция. <...> Новые подходы к изучению и оценке микробиоценозов влагалища //Республ. сборник научных трудов «Аутофлора человека в норме и патологии и ее коррекция». <...> Vaginal flora in health and disease // Clin. <...> 283] СТАНОВЛЕНИЕ ВОСПРОИЗВОДИТЕЛЬНОЙ СПОСОБНОСТИ БЫКОВ-ПРОИЗВОДИТЕЛЕЙ АМЕРИКАНСКОЙ СЕЛЕКЦИИ В ПЕРИОД ИХ АДАПТАЦИИ К УСЛОВИЯМ УРАЛЬСКОГО РЕГИОНА Бусыгина О.А. <...> В условиях современного мирового рынка наиболее остро возникает глобальная проблема продовольственного обеспечения в связи с ростом потребления продуктов питания, нестабильностью их производства и увеличивающимся дефицитом земель. <...> Среди направлений <...>
