APPLICATION OF SUNFLOWER MEAL AND CRUSHED FLAX SEEDS IN THE DIET OF DRY COWS

Abstract

The article deals with the issues of nutrient balancing of the diet of dry dry cows of the Simmental breed in the farm of the North Kazakhstan region. For the study, 3 groups of cows were formed. The first control group of animals was fed with the diet adopted on the farm, the cows of the second group were included in the diet of sunflower meal in the amount of 2 kg, and the third group of cows were given 1,5 kg of crushed flax seeds. According to the general nutritional value, diet structure and the ratio of the main nutrients, the groups differed in the content of crude protein and crude fat, which was higher in the experimental groups. So, in the second group, these figures were 15,9 % and 3,7 %, which is higher than the control by 3,7 % and 0,1 %, respectively, the third group also exceeded the control in these indicators by 2 % and 2,9 %. The inclusion of crushed flax seeds in the amount of 1,5 kg in the daily diet of dry cows made it possible to increase the content of crude fat to 6,5 %. Therefore, it can be stated that the protein level in this experiment was studied at different levels of crude fat and starch, that is, against the background of different energy sources.
