THE EFFECTIVENESS OF THE POLYMER COATING OF THE FEED TABLE FOR DAIRY COWS

Abstract

Many factors influence the milk productivity of cows. One of such factors is the technology of feeding animals, the element of which is the feed table and its coating. The article provides data on the effectiveness of using the polymer coating of the "Meadow of Health" fodder table in the technology of feeding dairy cows. As a result of the studies, it was found that the use of the "Meadow of Health" coating contributes to a significant decrease in microbial contamination: the number of microbial cells in group 1 after 5 months from the beginning of the study was more than 2, and 2 - 3.7 times less than in group 3 (P ≥ 0.95). The use of the cover of the fodder table "Meadow of Health" contributes to a reliably better (P ≥ 0.95) food consumption. Cows from the polymer feed table ate feed 7.0- 8.6% more than from concrete. Over the entire observation period, the cows of the 1st experimental group improved their performance by 13%, and the indicators of the 4th control group decreased by 9%. The increase in dairy productivity of cows is observed when transferring from the section with a concrete feed table to the section with the cover of the feed table "Meadow of Health." The average daily milk yield of cows with such a transfer within four months increases by an average of 0.4-13 kg. When transferring from a polymer feed table to a concrete one, a decrease in the average daily milk yield of cows is observed. Thus, the effect of the polymer coating of the feed table on the milk yield of cows was established. The calculation of the efficiency of using the polymer coating of the feed table showed that in the first month, due to the profit from the additionally received milk, the costs of the polymer coating pay off by 65.7-77.7%.
