COMPARATIVE EFFICIENCY OF USING PEPTIDE-AMINO ACID CHELATED PRODUCTS PAD-2 AND PAD-3 IN FEEDING SIRE BULLS

As a result of the studies, it was found that the use of peptide-amino acid chelated products PAD-2 and PAD-3 in feeding sire bulls contributes to an increase in quantitative and qualitative indicators of sperm production, by 3.8-14.8 and 2.5-19.7%, respectively, and also has a positive effect on morphological and biochemical blood indicators. A higher economic effect was found in the sale of sperm products obtained from the bulls, in the feeding of which the peptide-amino acid chelated product PAD-3 was applied. Additional profit from the sale of sperm from these bulls per head amounted to 585.37 rubles for 60 days of experience, which is 19.2% more than that of sires who received the peptide-amino acid chelated product PAD-2.
