Untersuchungen zur präventiven Magen-Darm-Strongyliden- Kontrolle bei Milchziegen mittels Esparsettenpellets

Summary

Dairy goats, naturally infected with gastrointestinal nematodes, were fed 700g sainfoin- or alfalfa-pellets per day, additionally to a non-tanniferous basic diet. The effect of the feeding on the parasite egg excretion per gramm faeces (EPG) was monitored over a period of 7 weeks. The trial was conducted in parallel at two sites; in France and in Switzerland. At both sites the same quality of sainfoin- and alfalfapellets were used. Compared to the alfalfa group the EPG of the sainfoin fed goats were reduced by 12% in France andby 18% in Switzerland. A repeated measurement analysis revealed no significant difference between the feeding groups at neither site. As it is very likely that the effect of condensed tannins on gastrointestinal nematodes is dose dependent, the relatively low absolute condensed tannin concentration might be jointly responsible for the absence of a significant effect.
