Qualitative indicators of the longest back muscles of fattened young pigs used in the diets of biologically active drugs
The article presents the data on the effect of the selenium preparation DAFS-25 separately, DAFS-25 in combination with the amino acid threonine, as well as DAFS-25 together with the enzyme preparation protosubtilin G3x, on the chemical composition and biological value of the longest back muscles of fattened young pigs. It is proved that the introduction of experimental groups of studied biologically active drugs into the diets of young pigs, in comparison with the control, contributes to an increase in the content of dry matter in the longest back muscle by 0.47-0.72% (P<0.05) and protein by 0.44-0.81% (P<0.05; 0.01). In animals of experimental groups, the protein quality index was also higher than that of the control group analogues, by 5.15-10.89%. At the same time, the fat content in the longest back muscle in young pigs of the control group was slightly higher than in animals of the experimental groups. However, the obtained differences in this indicator were statistically unreliable.
