Influence of feed additives on the hematological and biochemical parameters of the blood of lactating cows

Abstract

Increasing the milk productivity of cows is the main task facing the livestock industry of our country. The study of some hematological and biochemical blood parameters in dairy cows when different feed additives are included in their rations is an urgent research task. The purpose of the investigations was to study the hematological and biochemical parameters of the blood of lactating cows when using different feed additives in the ration. During the investigations, the influence of feed additives such as Zaslon 2+ (at a dose of 20 g/head/day to the main ration), Diatomite (100 g/head/day to the main ration) and Monosporin (70 g/head/day to the main ration) on the hematological and biochemical blood parameters of lactating cows has been observed. The studied feed additives are used for the adsorption of mycotoxins in feed, normalization of digestive processes, and improvement of the livability and productivity of farm animals. In order to study the influence of the tested feed additives on the hematological parameters of the blood of lactating cows under the conditions of the Troitsky area in the Chelyabinsk region, on four groups of cows selected according to the principle of analogues (age, live weight, productivity, breed, physiological condition) the scientific and economic experiment has been carried out. As the result of the investigations, data have been obtained indicating that the feed additive Zaslon 2+ at the dose of 20 g/head/day has the greatest effect on the metabolism in the body of lactating cows.
