ABSTRACT:
A device for oral administration to a ruminant animal includes a veterinary medicament, such as an anthelmintic, uniformly dispersed throughout an erodable sheet comprising an ethylene-vinylacetate copolymer. The sheet is rolled up and stuck together with adhesive backed paper strips for administration, and unrolls in the rumen to take up a planar configuration which is retained in the rumen. The sheet may be placed within a plastics netting envelope to give more controlled erosion and release of medicament.
