Abstract
Introduction. Today's feed market offers a variety of new products of plant and animal origin that increases the productivity of young sheep. Using feed supplements can help farmers to fully realize the genetic potential of wool-and-meat genotype sheep.Study objects and methods. We studied the effect of a whole milk replacer (skimmed powdered milk) and an ORGANIC high-protein feed supplement on the growth of young sheep and the quality of their meat. In particular, we determined the effect of starter feeds on the biochemical and morphological parameters of sheep blood at the Vtoraya Pyatiletka Breeding Farm, Stavropol Krai.Results and discussion. Substituting starter feeds with a whole milk replacer and an ORGANIC supplement for the standard feed in the diet of sheep aged 0-4 months increased metabolic energy (by 12.5%), crude protein (by 22.4 and 25.5%, respectively), lysine (by 24.8 and 21.4%, respectively), and methionine + cystine (by 31.0%). The starter feeds also led to higher live weight (by 29.6 and 33.7% (P < 0.001)), absolute and average daily gain (by 24.6 and 29.1% (P < 0.001)), slaughter weight (by 36.5 and 42.1% (P < 0.001)), slaughter yield (by 2.50 and 2.96 abs.% (P < 0.05)), and meat marbling (by 3.6 and 11.7%). The number of muscle fibers increased by 2.1 and 3.3%, respectively. Additional profits rose from 1761.5 to 2091.5 rubles per head and the product profitability reached 50.5-57.9%.Conclusion. The starter feeds containing a milk replacer and an ORGANIC feed supplement proved effective for sheep aged of 0-4 months in the suckling period, ensuring live weight of 39-40 kg and improving meat quality and productivity.Keywords
