Изучено влияние на репродуктивную функцию коров белково-витаминно-минеральных концентратов (БВМК) с кормовой добавкой «AMG-COMPLEX», состоящей из эфирных масел и растительных экстрактов. Для проведения опыта были сформированы контрольная и опытная группы по 70 голов с учетом количества дней до отела из коров второй и третьей стельности. Животным контрольной группы скармливали основной рацион. Для коров опытной группы были составлены рационы с БВМК, которыми заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Они получали БВМК для сухостойных коров в количестве 300 г на 1 голову в сутки с 60-го по 20-й день до отела и по 200 г на 1 голову в сутки с 20-го дня до отела. После отела 60 дней им скармливали БВМК для раздоя в количестве 1200 г на 1 голову в сутки. Использование БВМК в рационах коров опытной группы способствовало улучшению у них репродуктивной функции и снижению частоты гинекологических заболеваний после отела в 4,5 раза. Индекс осеменения в опытной группе составил 1,73 (P≤0,05), что на 0,76 ниже, чем у животных контрольной группы. Средняя продолжительность сервис-периода в опытной группе составила 87,71 дня (P≤0,01) и была короче, чем в контроле, на 14,72 дня. The effect on the reproductive function of cows of the protein-vitamin-mineral concentrate with the feed additive ʺAMG-COMPLEXʺ, consisting of essential oils and plant extracts, was studied. To experiment, taking into account the number of days before calving, control and experimental group of 70 heads each were formed from cows of the second and third pregnancy. In the scientific and economic experiment, the cows of the control group consumed the feed of the main rations. For the cows of the experimental group rations were made with PVMC, which replaced the proportional amount of concentrated feed and a part of the vitamin-mineral premix. They received PVMC deadwood in the amount of 300 g per 1 head per day from 60th to 20th day before calving and 200 g per 1 head per day 20 days before calving. 60 days after calving they received PVMC lactation in the amount of 1200 g per head per day. Feeding PVMC to cows of the experimental group contributed to the improvement of reproductive function and a decrease in the frequency of gynaecological diseases after calving by 4.5 times. The insemination index in the experimental group was 1.73 (P≤0.05), which is 0.76 lower than in the animals in the control group. The average duration of the service period in the experimental group was 87.71 days (P≤0.01) and was shorter than in the control by 14.72 days.
