Studying the Feeding of a Buffer Multicomplex in the Diet of Newly Calved Highly Productive Cows

Abstract

Abstract The research has been carried out to study the feeding of the buffer multicomplex in the diet of newly calved highly productive cows. The studied feed additive includes sodium bicarbonate, magnesium oxide, vitamin-mineral premix, probiotic complex, yeast complex, chalk, monocalcium phosphate, phosphate salt, organic chromium, essential oil extracts. In animals of the group where 0.5 kg of compound feed was replaced with 0.5 kg of a buffered probiotic multicomplex, the daily milk yield was significantly higher by 10.9% than in the control. The cost of dry matter for the production of 1 kg of milk decreased in the experimental group relative to the control by 8.6%, the cost of crude protein–by 5.8%. Biochemical parameters of blood serum of all cows corresponded to the norm. In the control, the level of glucose in the blood serum of cows was 3.1 ± 0.20 mole / l; in the experimental group, there was a significant increase in this level by 12.9% within the normal range, which indicates an improvement in carbohydrate metabolism in the body of cows in the new calving period in the experimental group. The level of alkaline phosphatase significantly increased in the second group by 53.4. This indicates an improvement in mineral metabolism in the body of the cows in the experimental group. The microbiological indicators of the ruminal fluid of cows were within the normal range. The results of washing feces on the analyzer showed that the best digestibility of fiber was observed in the experimental group.
