Located in Clydebank, Scotland, we contract manufacture sustained-release veterinary bolus products, in accordance with both FAMI-QS and GMP standards, for the health and wellbeing of grazing or forage fed livestock.

We have been in the business of contract-manufacturing quality boluses in Scotland since 1988.

Our products optimise growth rates in the young, aid in easier calvings, help grow strong healthy calves, reduce the calving spread and optimise general condition in cattle.

Active components are copper, cobalt, selenium, manganese, zinc, iodine, and vitamins A, D3 and E.

Our products were created as a result of research and development by the late Dr. Norman Ritchie and his colleagues at the University of Glasgow Vet College during the 1980’s. Norman started our business in 1988 in order to bring the product to market and we have operated from our current premises in Clydebank since 1993.
