Abstract
The article describes results of application of «Polysol Omega-3» and «Omega-3 Active» feed additives in rations of young pigs during fattening period and their influence on hematological and biochemical parameters of animals‘ blood. The research was carried out at the pig breeding complex SPK named after N.K. Krupskaya of Melekesskyi district of Ulyanovsk region. The basis of «Omega-3 Active» supplement is flaxseed oil, which contains 60% of polyunsaturated fatty acids and the prevailing proportion of Omega-3. The feed mixture «Polysol Omega-3» includes fatty acids in combination with a complex of biologically active and mineral substances. In addition to studying the productivity and quality of pig production, the study of the effect of these additives on morpho- biochemical status of blood and, in particular, lipid metabolism is of scientific interest. The results of the analysis showed that in case of application of these feed additives in the rations of young pigs, the concentration of erythrocytes in their blood was higher in comparison with control analogs by 1.13 ... 3.56 %, hemoglobin by 7.97 ... 14.15 % (P <0.01), the total protein content by 6 , 75 ... 7.88 %. This is confirmed by improvement of redox processes and metabolism in their bodies. The ration enrichment with the analyzed additives contributed to better usage of fats in feed, which is confirmed by the studied parametres of lipid metabolism (cholesterol, HDL, LDL, triglycerides). The activation of biosynthetic processes had a positive effect on average daily gain of pigs, as a result of which the early maturity of animals increased by 9 ... 23 days
