ПОВЫШЕНИЕ АДАПТИВНЫХ ВОЗМОЖНОСТЕЙ ОРГАНИЗМА МОЛОДНЯКА КРУПНОГО РОГАТОГО СКОТА С ПРИМЕНЕНИЕМ КОМПЛЕКСА БИОЛОГИЧЕСКИ АКТИВНЫХ ВЕЩЕСТВ

Abstract

A multifunctional feed additive has been developed in the form of an additional nutrition complex, which contains a probiotic of cellulose-amyl-proteolytic action, shungite mineral, which has adsorbing and antioxidant properties, a “protected” choline of lipotropic-hepatoprotective action, and flaxseed cake in known proportions. The studies were carried out under the conditions of the Federal State Unitary Enterprise “Klenovo-Chegodaevo” on two groups of calves of early postnatal ontogenesis of black-motley holsteinized breed (n = 8). Animals of the experimental group from a month of age received CAF of 40 g / 100 g of live weight. To study metabolic processes in the body (n = 8), at the end of a three-month experiment, blood samples were taken from the jugular vein and biochemical and hematological parameters were determined. The positive effect of the additive on the course of nitrogen metabolism was revealed, with an increase in the concentration of total protein in the blood serum by 5,3% (P<0,05), as well as albumin by 7,3% (P<0,05), with an increase in A / G coefficient, against the background of a decrease in urea concentration by 7,0% (P <0,001). The use of CAF contributed to an increase in the energy supply of the animal organism, as evidenced by an increase in creatinine by 8,2% (P<0,05), glucose concentration by 19.8% (P <0.05), and a higher level of alkaline phosphatase (by 20,5%) (P<0,05). Evidence of an improvement in carbohydrate-fat metabolism is an increase in phospholipids by 45,2% (P<0,001), HDL by 14,0% (P<0,01), with a decrease in bilirubin levels by 23,8%. A higher level of metabolic processes in the body with an improvement in the functional activity of the liver may be indicated by an increase in the activity of creatine kinase by 28,8% (P<0,01), lactate dehydrogenase (LDH) by 10,0% (P<0,05), and cholinesterase by 15,1%, gammaglutamyltranspeptidase (GGT) by 3,9%. The use of CDPs contributed to an increase in hemoglobin in the blood by 9.8% (P<0,05), red blood cells by 7,0%, hematocrit by 10.0%, with a decrease in the level of leukocytes by 13,1%. The absolute increase in live weight of calves over 90 days of experiment was 66,88 ± 2,66 kg in the control group, 77,87 ± 3,04 kg in the experimental group, and average daily gain in live weight was 743,11 ± 29,56, and 865, respectively , 22 ± 33,78 grams (P<0,05), with a difference of 16,4%, with a more pronounced effect of the CAF during the period of a complete transition to nutrition with vegetable feed.
