LOW-PROTEIN FEED COMPOSITION FOR PROMOTING FEED CONVERSION EFFICIENCY OF RUMINANTS

摘要

The present invention pertains to a low-protein feed composition for promoting the feed conversion efficiency of ruminants, the low-protein feed composition containing: a carbohydrate source; a protein source containing soybean meal; a fat source; and β-mannanase as an enzyme, wherein the content of the soybean meal is in the range of 4.0-7.0 parts by weight with respect to 0.1 parts by weight of the β-mannanase. In the low-protein feed composition, which has a lower protein content than conventional feed compositions, the mixing ratio of soybean meal and β-mannanase is optimized to reduce the amount of soybean meal used. Thus, the low-protein feed composition has the effect of increasing feed conversion efficiency (FCE) while having good economic feasibility.
