摘要 |
A post-rumen effective composition for oral administration to ruminants containing a bioactive substance molecularly dispersed with a basic polymer. The bioactive substance is miscible with the polymer and may be a vitamin, antibiotic, peptide or anti-inflammatory agent. The basic polymer contains from about 1 percent to about 25 percent by weight of nitrogen and is resistant to a pH of greater than about 5 and soluble or swellable at a pH of less than about 3.5.
