ОТЕЧЕСТВЕННЫЕ ФЕРМЕНТЫ В КОМБИКОРМАХ ДЛЯ СВИНЕЙ

Abstract

One of the main promising areas in the technology of pigs feeding and the development of the industry is the use of enzyme preparations. Enzymes are specific proteins, that fulfill the role of biological catalysts in a living organism. Enzymes, unlike hormones and biostimulants, do not act on the animal organism, but on the components of the feed in the gastrointestinal tract, they do not accumulate in the body and products of animal husbandry. The scientific and economic experience was carried out on the basis of the CJSC “Progress” enterprise of the Yalchik district of the Chuvash Republic from May to October 2015. Studies were carried out on young pigs of large white breed at the age of 2 to 7 months. Three groups of clinically healthy gilts were formed according to the principle of analog groups of 12 heads in each one. The duration of scientific and economic experience was 150 days. The pigs of all groups were in the same conditions of feeding and maintenance, and they were fed mixed fodders in accordance with detailed feeding standards. Control samples are animals that received mixed feed, used in the farm when feeding young pigs. The feedstuff of the first experimental group was enriched additionally with a mixture of enzyme preparations №1 and №2, the second test group with mixture №1 and №3. At the beginning of the experiment in all groups, the average live weight of pigs was almost the same and amounted to 17.8 to 18.1 kg. At the end of the experiment, this parameter in the control group was 112.0 kg, in the first test group - 125.1 kg, in the second test group - 120.3 kg. Feed costs per 1 kg of gain were 4.82 energy feed unit in the control group, 4.25 energy feed unit in the first group and 4.44 energy feed unit in the second test group. The production was received for 1 ruble of additional costs in the first experimental group to 8.29 rubles and to 6.06 rubles in the second experimental group.
