PRACTICAL ASPECTS OF BIOLOGICAL PRODUCTS APPLICATION IN PIG BREEDING
In recent years, enzyme preparations have been particularly effective in feeding pigs, which can significantly increase the usefulness of grain mixtures produced on farms. This is necessary, since in the first weeks of life, the stomach pepsin is inactive, amylase, sucrose and maltase are inactive, and trypsin and lipase are highly active. When conducting scientific and economic experience, it was found that the pigs of the 2nd experimental group more efficiently used nitrogen from the accepted and digested by 13.7 and 10.6% compared to the control and by 11.2 and 8.5% in comparison with analogues of 1 experienced. Also, the data of the research results confirm that with age, the level of total protein in animals rises, which is natural, since the muscle mass consisting of protein increases. This indicator in the II-experimental group was 5.3% higher than in the control, and in the experimental I - 2.8%, but the protein content in this group at the beginning of the experiment was the lowest, and 1.8% less than the control group.
