Pellets adapted to be orally administered to ruminants are disclosed. The pellets have a core comprising a nutrient and/or medicament, and a coating which protects the core in the environment of the rumen to allow utilization of the core in the abomasum and/or intestine. The coating comprises a polymeric matrix which is resistant to acid and a substance dispersed throughout the continuous matrix which is leachable from the matrix in the environment of the abomasum but not the rumen. |
