Currently, the main volume of dairy products produced comes from dairy complexes equipped with milking parlors with automatic milking system. However, as practice shows, in the automatic milking system, settings may fail and be incorrectly set, leading to negative effect on mammary gland of cows. Hence, the goal of the research was to study the effect of settings of automatic milking equipment (vacuum in teat chamber, minimum milk flow when removing milking machines) on functional state of mammary gland of high-yielding lactating cows. The experiments were carried out in two milking parlors. At milking parlor 1, there was no maintenance of milking machine for three years. At milking parlor 2, there was regular maintenance with testing of each milking machine. It was established that with regular maintenance (milking parlor 2), the “milking vacuum” was in the range of 37…39 kPa, in the main pipe - 40…42 kPa, i. e. the difference was no more than 2-3 kPa. Insufficient vacuum in teat chamber (34…36 kPa) resulted in 1.6-2.0-fold increase in duration of milking, 2.5-4.0-fold increase in number of cows with udder irritation, 3.0-4.2-fold increase in incidence of subclinical mastitis, 3.2-11.8-fold increase in incidence of clinical mastitis, 2.0-3.2-fold increase in number of somatic cells in collected milk. Increase in minimum milk flow up to 450…500 g/min after turning off the milking machine ensures 3.9-fold reduction in the number of cows with udder irritation, 4.1-fold reduction of cows with subclinical mastitis, 21.2-fold reduction of cows with clinical mastitis, and 4.2-fold decrease in the number of somatic cells in collected milk (145.5 thousand/ml that corresponds to premium milk).</p></abstract><trans-abstract xml:lang="ru"><p>Одним из важнейших аспектов получения молока высокого санитарного качества является функционирование доильной техники. Основной объем получаемой молочной продукции приходится на молочные комплексы, оснащенные доильными залами с автоматизированной системой доения. Однако, как показывает практика, в системе автоматической дойки возможны сбои настроек, их некорректное установление, приводящие к негативному воздействию на молочную железу коров. Цель исследования - изучение влияния параметров настроек автоматизированного доильного оборудования (вакуум в подсосковой камере, минимальный поток молока при снятии доильных аппаратов) на функциональное состояние молочной железы высокопродуктивных лактирующих коров. Исследования проведены на двух доильных залах. В доильном зале 1 не проводили техническое обслуживание доильной установки на протяжении трех лет, в доильном зале 2 - осуществляли регулярное техническое обслуживание с тестированием каждого доильного аппарата. Установлено, что при регулярном проведении технического обслуживания (доильный зал 2) «вакуум доения» находится в пределах 37…39 кПа, в магистральной трубе - 40…42 кПа, т. е. разница составляет не более 2…3 кПа. Недостаточный вакуум в подсосковой камере (34…36 кПа) способствует повышению продолжительности доения в 1,6…2,0 раза, увеличению количества коров с раздражением вымени - в 2,5…4,0 раза, заболеваемости субклиническим маститом - в 3,0…4,2 раза, клинически выраженным маститом - в 3,2…11,8 раза, числа соматических клеток в сборном молоке - в 2,0…3,2 раза. Увеличение минимального потока молока при отключении доильного аппарата до 450…500 г/мин обеспечивает снижение количества коров с раздражением вымени в 3,9 раза, больных субклиническим маститом - в 4,1 раза, клинически выраженным маститом - в 21,2 раза и числа соматических клеток в сборном молоке - в 4,2 раза (145,5 тыс./мл, что соответствует молоку высшего сорта).</p></trans-abstract><kwd-group xml:lang="en"><kwd>cattle</kwd><kwd>lactation</kwd><kwd>vacuum</kwd><kwd>milk</kwd><kwd>somatic cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>крупный рогатый скот</kwd><kwd>лактация</kwd><kwd>вакуум</kwd><kwd>молоко</kwd><kwd>соматические клетки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Inzaghi V, Zucali M, Thompson PD, Penry JF, Reinemann DJ.
