Modern Energy Supplements for Correction of Physiological and Biochemical Status of Cattle

Abstract

Energy supplements are often used to normalize the physiological and biochemical status of cattle during milking; to increase the yield and make up for the energy lack in the diet. The objective of this research was the practical justification for the use of modern energy supplements in the diets of highly productive cows during milking. The scientific novelty lies in the fact that the effect of energy feed supplements ―Lacto S‖ and ―Extima 100‖ on productive, physiological and biochemical parameters of Black Pied cattle during milking has been studied for the first time. We used generally accepted zootechnical biochemical and statistical research methods. The results showed that the use of 200 g per animal per day (the 1st experimental group) of the energy feed supplement ―Lacto S‖ in the diets of highly productive cows increased their milk productivity by 8.88% (P <0.05), compared with the analogues of the control group. In this case, the service period of cows of this group was 9 days shorter, and duration of the calving interval was 15 days shorter, than of the analogous to the control group. The glucose level in the blood serum of cattle of the 1st experimental group was 41.38% (P <0.05) higher than in the control group. The lowest urea content was in the blood serum of the 1st experimental group – 4.10 mmol/l, which is 15.37% lesser when compared to the control group. The creatinine content in animals of the 1st experimental group was 8.13 mmol/l, or 10.48% more than in the control group. These energy supplements contributed to a decrease in alkaline phosphatase in blood serum in the 1st experimental group by 8.62% and in the 2nd experimental – by 5.94%, compared with the control group.
