The success of a scientific workshop depends on a delicate blend of many types of ingredients. Most important is to select a provocative topic which is at the forefront of a current investigative study. Coupled together with a relatively small but distinguished group of active research scientists known for their continued record of contributing significant findings, one has the firm foundation for an exciting and rewarding investment of time and effort. This was the setting for the first workshop organized by the European Association for Veterinary Pharmacology and Toxicology. Ruminants have been domesticated for many centuries and have served mankind as a source of dairy products, meat, wool and power. The ruminant stomach has long been - and still is - a major concern for physiologists, pathologists, clinicians and pharmacologists. This workshop was organized and convened in an attempt to strengthen the basic science of the ruminant stomach, as it applies to an economically important group of mammals. To achieve this, various topics were covered by specialists which ensured presentation of new data, followed by discussions. In this book, reviews are presented on the different topics: motility (control and regulation, neurotransmitters and endogenous substances involved); flow of digesta (comparative aspects, role of content and metabolites); food intake; rumen metabolism (chemical manipulation, metabolism of xenobiotics and drugs); pharmacology of forestomach motility and, the reticulo-rumen as a pharmacokinetic compartment.

The third congress ofthe European Association for Veterinary Pharmacology and Toxicol­ ogy (EAVPT) was held in Ghent, Belgium, from 25 to 29 August 1985. Part I of the Proceedings of this congress contains the abstracts of all invited lectures, oral communi­ cations and poster communications, presented at the congress. The invited lectures are now published (this volume) in extenso as Part II of the Proceedings. The editors wish to thank all invited speakers for their active contribution to the success of the third congress of EAVPT. They are very grateful to Dr. P. De Backer for compiling all manuscripts, Dr. P. Lees for scientific amendments, Miss B. Vermeesch and Dr. R. Lefebvre for preparing the camera ready copy and MTP Press for literary advice and publishing. A. S. J. P. A. M. van Miert M. G. Bogaert M. Debackere xi Contributors AMEND J.F.
