FEED ADDITIVE COMPOSITIONS AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention concerns animal feed additives. Disclosed are solid rumen bypass feed additive compositions containing oils which comprise polyunsaturated fatty acid (PUFA). The compositions are prepared by mixing a solid carrier and hydrogenated fat until homogeneity, mixing the PUFA-containing oil to the homogenized mixture, mixing melted hydrogenated fat having a higher melting point than the carrier/hydrogenated fat/oil mixture until homogeneity, mixing the resulting mixture at room temperature, and allowing the mixture to rest at room temperature before packaging. Methods are also disclosed for producing milk and dairy products enriched in PUFA by using said novel feed additive compositions.
