“…In BVD unfavourable herds reproductive disorders in cows associated with embryonic losses up to 45 days of gestation period made up to 20.2%; the total average level of abortions in cows and heifers was 6.1%, the level of pregnant animals abandonment -9.3 %, which exceeded the average regional indicator by 2 times. The main share of perinatal losses was the birth of non-viable calves, the stillbirth rate was 14.1%, which is 3.5 times higher than the regional average [6]. In reproductive disorders, the first place in the antigenic structure was occupied by BVDV, 23%, the second place -by Chlamydia spp., 18.3%.…”

“…For veterinary science and practice, the issues of biological well-being of farm animals under conditions of technological processes intensification of livestock production are now extremely acute. According to both Russian and foreign researchers, industrial livestock breeding serves as one of the main reasons for violation of the evolutionary mechanisms balance of relationships between the farm animals environment and microorganisms of various taxonomic groups persistently circulating in this environment [4,6,8,13,15].…”

“…В современной отрасли молочного животноводства большое значение отводится проблеме увеличения производства молока, одним из важнейших условий для этого является качественное совершенствование существующих пород и повышение их генетического потенциала [1,6,10]. Все большее значение уделяется качеству получаемого сырого молока [1,3,6].…”

“…Предыдущие метагеномные исследования позволили обнаружить резкие различия в составе микробиоты у здоровых коров и коров с репродуктивными заболеваниями (7,8). Раннее выявление микробиоты, вызывающей воспалительные заболевания репродуктивного тракта, важно для проведения своевременных лечебно-профилактических мероприятий и предотвращения инфекционного процесса (9)(10)(11).…”
