Environmentally-friendly enzyme compositions in animal feeding

Abstract

The realization of the genetic potential of farm animals is first of all determined by the complete feeding, which is determined by its balance in accordance with the needs of animals with a certain physiological state and level of productivity. The study of enzyme compositions in the feeding of mammalian farm animals that promote better digestion of incoming nutrients is an urgent issue. Feed enzymes not only increase the digestibility of individual feed components, but also allow you to increase the rate of input of inexpensive raw materials “rich” in anti-nutritional factors without compromising the health and productivity of the animal. The purpose of the research was to study the use of enzyme compositions in the feeding of cattle and pigs. The results of the study of enzyme compositions in the rations of lactating cows during the period of increasing the milk yield and pigs during the period of rearing and fattening have been presented in the article. The input of enzyme additives with a cellulolytic effect in the rations of cows had the positive effect on the digestibility of nutrients in the feeding ration, milk productivity, and the composition of milk. During the first 100 days of lactation milk with natural fat content was produced from cows of the 1st experimental group by 5,5 % more and from cows of the 2nd experimental group by 13,8 % more than from animals of the control group. In terms of 4 % milk the animals of the 1st experimental group exceeded the control analogues by 7,32 % and in the 2nd group by 18,1 %. The input of 1 kg/t of feed in the diet of the multienzyme composition “Kemzaym W” animals allowed us to get 81,7 kg of additional gain, more profi t compared to the 1st experimental group, where the additional gain was 24,7 kg. The use of the multienzyme composition “Kemzaym W” in the amount of 1 kg/t in the diets of young pigs had the positive effect on the digestibility of raw nutrients, on the increase in live weight and average daily gains, on the yield of meat and the quality of carcasses.
