Helminth control practices and infections in growing pigs in France

Internal parasite control practices and helminth infestations were investigated in 78 pig farms in France. Pooled faecal samples were taken from pens housing 16-week-old pigs. Samples were examined by coproscopy. Farm practices were checked for the risk factors of infestation previously described in literature. Information was obtained during a visit of the facilities and an interview with the farm owner/manager. Anthelmintics were used in most herds (97%). Treatments were routinely prescribed, such as flubendazole in the diet of the piglets and ivermectin for sows. Finisher pig infestation may occur despite these treatments: five samples in our study contained helminth eggs, four samples contained strongylid eggs (Hyostrongylus rubidus or Oesophagostomum spp.), and one sample contained Trichuris suis eggs. We can conclude that helminths are controlled, but that parasites can still be present in indoor intensive pig operations. Hygiene efforts must be continued. (C) 2002 Elsevier Science B.V.
