ABSTRACT:
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 is also provided to allow utilization of the core in the abomasum and/or intestine. The coating comprises a polymeric matrix which is resistant to the mildly acidic environment of the rumen, and a hydrophobic substance and a flake material dispersed throughout the continuous matrix. The core may contain a neutralizer if desired. The continuity of the polymeric matrix is destroyed in the more acidic environment of the abomasum.
