Summary
A côté d'un emploi réfléchi des traitements anthelminthiques, la maîtrise de ce parasitisme doit s'appuyer sur l'amélioration de la réponse de l'hôte et sur la gestion raisonnée de la principale source de contamination : les prairies. Le pâturage mixte (alterné ou simultané), notamment entre bovins et ovins, permet de réduire les infestations parasitaires : la forte spécificité des strongles pour leur hôte usuel explique la décontamination résultant du pâturage par une seconde espèce. Cet article fait le point sur les principaux résultats associés à ces pratiques de pâturage mixte. Les résultats parasitologiques et zootechniques sont généralement favorables dans le cas des ovins. Les limites potentielles inhérentes à ce type de pâturage sont également évoquées. Les méthodes évoquées sont applicables en agriculture biologique.
Summary translation
Gastro-intestinal trichostrongylosis is one of the main sanitary constraints encourntered when ruminants are grazing pastures managed according to the rules of Organic Farming. In traditional farming too, there is an ever sharper demand for the reduced use of chemical inputs. What are the prospects opened by mixed grazing for the control of this kind of parasitism ?
Apart from a reasoned use of anti-helmintic treatments, the control of these parasites should be based on an improved response of the host and by an adequate management of the pastures - which are the main source of infection - in order to reduce the contact with infectious larvae. Mixed grazing by different hosts, notably by cattle and sheep, is one of the methods used to reduce the infectiousness of the pastures. It is based on the relatively high specificity of many nematode species towards one host, so that the infectiouness of a pasture will be diminished by a second host's grazing. The advantages and limits of mixed grazing, either alternately or simultaneously, are discussed with regard both to parasite infection and to animal productivity. Mixed gazing involving sheep gives generally favourable results. The potential limits encountered with this kind of grazing practice are also mentionned. The methods mentioned above are applicable in organic farming.
