Study of Scar Content in Cows When Using Carbohydrate-Vitamin-Mineral Concentrate «LS»

Abstract

Scientific studies of feeding dairy cattle prove that it is most rational to balance rations according to standardized nutrition indicators due to concentrates, which contain all the necessary nutrients in the main diet, consisting of bulky feed (succulent and rough). The advantage of using protein supplements in the feeding of farm animals is that there is no need for oncoming transport of grain fodder and animal feed, which significantly reduces the cost of livestock production. The digestive apparatus of ruminants, due to the presence of pre-stomachs, is adapted to the absorption and digestion of a large number of coarse plant foods. The main feature of the processes of digestion of ruminants is that the food eaten by animals is exposed to microorganisms in the rumen. Ammonium and other nitrogenous compounds are an accessible form of nitrogen for organisms from which a microbial protein is synthesized in a rumen. This protein and unsplit protein feed are sources of coverage of the amino acid needs of the animal. The contents were investigated: pH, the total concentration of volatile fatty acids (VFA) - butyric, propionic and acetic; the total number of microorganisms and number of ciliates. The introduction of the carbohydrate-vitamin-mineral concentrate «LS» in the diets of dairy cows for 30 days contributed to an increase in the name of bacteria by 3.3±3.4% and protozoa by 6.7±4.1%. In the cicatricial content of the experimental groups, the number of volatile fatty acids increased by 12.4±2.4% and propionic and butyric acids by 3.4±3.1 and 5.7±2.7% in relation to the control group of cows.
