This study aims to effectively convert C. korshinskii into high-quality feed, improve the quality of milk and meat of herbivores and increase production. [Methods] The utilization of C. korshinskii in feed was studied in various aspects, the factors were selected, the level was determined, and the multi-factor experiment—orthogonal experiment was conducted. [Results] The effect on the growth of sheep was in the order of silage > C. korshinskii feed > corn stalk silage > hay meal, and the effect on the growth of goats was in the order of hay meal > C. korshinskii feed > silage > corn stalk silage. [Conclusions] From the analysis of the range results, the best level combination was selected: in different growing seasons, C. korshinskii branch and leaf silage in full-bloom stage had the greatest effect on the growth of sheep and goats, and the fattening effect was the best;among the different silage methods of C. korshinskii, the C. korshinskii—corn stalk mixture silage had a good feeding effect for sheep and goats.展开更多
