Veterinary Review and Practice Heart magazines have ceased publication.
The former was first launched 15 years ago by John Alborough, and sold to Onstream Communications in May 2007.
Mark Johnston, Managing Director of Onstream Communications said: "It wasn't commercially viable running a full publishing team for two magazines, especially in the current economic environment, so we're consolidating our activities and concentrating on electronic media".
These include the peer-reviewed online clinical information services: Canis, Felis, Equis and Lapis and the provision of websites for veterinary practices and companies wishing to promote themselves and their products and services.
