The influence of a complex energy and mineral additive on the productivity and morphological and biochemical status of blood in cows

Abstract

The results of research on the study of morphological and biochemical parameters of blood and milk productivity of lactating cows as a result of feeding a complex energy and mineral additive have been presented in the article. In addition to the main ration, animals of the 2nd and 3rd experimental groups received an energy additive in the amount of 210 and 220 g, as well as a mineral additive of 40 and 30 g per head/day. The results of the studies showed that the animals of the experimental groups that consumed the energy and mineral complex had normalization of mineral and carbohydrate metabolism. It was noted that the inclusion of a complex energy and mineral additive in the ration of animals of the 2nd and 3rd experimental groups contributed to an increase in the number of erythrocytes by 1,9 and 2,6 %, leukocytes by 12,2 and 13,9 %, hemoglobin by 2,0 and 2,5 %, total protein by 2,3 and 2,7 %, calcium by 6,2 and 12,1 %, phosphorus by 12,3 and 13,6 %, magnesium by 8,2 and 13,4 %, glucose by 2,9 and 5,6 %. Milk yield in the group of cows for 100 days of lactation in the 1st control group was 19700 kg of milk, in the 2nd experimental group it was by 7,9 % more, and in the 3rd experimental group by 10,4 % more. The fat content in the milk of cows of the experimental groups was higher by 0,1 3 and 0,15 abs.%, and protein by 0,07 and 0,09 abs.%. Revenue from the sale of milk in the 2nd and 3rd experimental groups increased by 7,9 and 10,4 %, the level of profi tability of milk production by 6,70 and 8,02 abs.% compared to the 1st control group. Consequently, the feeding of the new energy and mineral additive had a positive effect on the physiological state of the animals, allowed to increase the dairy productivity of cows and the profi tability of milk production.
