title: Principles, objectives and methods for the control of the gastro-intestinal parasites of pigs in France.
abstract: Parasitic levels are considered in relation to the size of farms and according to the application of anthelminitic programmes and the age groups of the animals. The most common and important parasites in France against which systematic control measures should be taken are Oesophagostomum, Ascaris and Hyostrongylus in pregnant sows, and  Oesophagostomum and Ascaris in piglets at weaning and fattening pigs. Strongyloides and Trichuris are found occasionally but could be sometimes important (Mestastrongylus is anexceptional finding). As  regards the use of anthelmintics, emphasis is placed on treatment of sows at parturition, or of piglets on transfer to the growing units, with two treatments being given at an interval of 14-21 days. Continuous administration in the food is a complementary solution. Specific treatments for the control of Trichuris and Strongyloides are also examined. In the control of parasites the strict observation of the rules of hygiene is also very effective.
