A helically-shaped medicated veterinary system suitable for delivery of a drug to the vaginal cavity of a female non-human mammal, the system comprising a three layered polymer fibre comprising:
- (a) a polymer core comprising a drug;
- (b) a polymer intermediate layer comprising a drug covering the core;
- and
- (c) a polymer skin comprising a drug covering the intermediate layer,
- wherein the polymeric material in the polymer core, the polymer intermediate layer and the polymer skin comprise ethylene-vinyl acetate copolymer, and
- wherein the system comprises a number of loops in the range of more than 1 to 10, and
- wherein the outer dimension of the system, when inserted into the vaginal cavity, substantially coincides with the inner dimension at the cervix point of the vaginal cavity.
