CHANGING THE RATIO OF FEED IN THE DIET – A TECHNOLOGICAL WAY TO INCREASE SCAR FERMENTATION AND PRODUCTIVITY OF ANIMALS

An important technological technique in production in order to increase the level of assimilation of feed by animals and increase their productivity is the ratio of different types of feed in the diet. Under these conditions, animals change the course of metabolic processes in the rumen and cause changes in metabolism, activate or inhibit the adsorption of precursors by breast tissue of cows for the synthesis of milk components. To this end, we studied the processes of cicatricial fermentation of the conditions of change in the ratio in the diet of green fodder, grass pellets and grain concentrates. This technique allows to intensify the processes of scar fermentation, increase the adsorption capacity of breast tissue of animals, accompanied by increased synthesis of volatile fatty acids, in which the proportion of acetic acid in animals of the second and third groups increases during the experiment by an average of 1.1-21.17 times (p<0.05). The increase in the content of LH in the scar of animals of the second and third groups was possible due to the increase in the content of the scar of amylolytic microorganisms on average during the experiment by 1.25 times (p<0.05), proteolytic 1.24 times (p<0.05), and cellulolytic 1.27 times in animals of the second group and 1.68 times in cows of the third group (p<0.01). All this affected the amino acid composition of the scar content of animals of the second group in which the content of essential amino acids was 8.24%, and in animals of the third group by 12.86% more than in cows of the first group. The total amino acid pool of the contained scar was probably larger in the cows of the experimental groups, because the replacement of amino acids in it was found by 10.0-10.8% more than in the animals of the first group. The level of breast tissue of cows with precursors for the synthesis of milk components due to changes in the ratio of different groups of feeds in the diet increased their absorption capacity during intensive lactation, which indicates a positive effect on the productivity of cows
