Protein-vitamin mineral complex "Status" - the milking cows diet main component

The purpose of reseach is to study the effect of the STATUS protein-vitamin mineral complex on the reproductive function and milk production of lactating cows. The influence on the reproductive function of cows of protein-vitamin mineral concentrate (PVMC) with the AMG-COMPLEX feed additive, consisting of essential oils and plant extracts, was studied. To conduct the experiment, taking into account the number of days before calving, 1 control and 1 experimental group of 70 animals were formed from cows of the second and third pregnancy in each. In the scientific and economic experiment, the cows of the control group consumed the feed of the main diets. For the cows of the experimental group, diets with PMMA were prepared, which were replaced with a proportional amount of concentrated feed and part of the vitamin-mineral premix. Cows of the experimental group received PVMC for dry cows in the amount of 300 g per head. per day from the 60th to the 20th day before calving and 200 g per 1 goal. per day 20 days before calving, and after calving 60 days received PVMC for milking in the amount of 1200 g per 1 animal per day. The introduction of the complex into the diet of animals during lactation promotes better absorption of nutrients, increases metabolism. This has a positive effect on their milk production. The average daily milk yield during the period of milking in the cows of the experimental group was higher by 16.5 % than in the animals of the control group. The same is typical for other periods - the middle and the end (higher by 11.4 and 8 %, respectively). Feeding PVMC to the cows of the experimental group contributed to the improvement of reproductive function and a decrease in the incidence of gynecological 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 of the control group.
