Einsatz von Esparsette bei mit Haemonchus contortus infizierten Lämmern

Abstract

The objective of this study was to examine the effect of different proportions of dried sainfoin (Onobrychis viciifolia) in the ration against the nematode Haemonchus contortus in lambs. 24 lambs were allocated to 4 groups. Each group received 750 g barley daily. Group KG received only hay, Group VG1 20 %, group VG2 50 % and group VG3 80 % of sainfoin. Individual fecal egg count (FEC) and live weight were performed weekly. All lambs were infected over the whole study period of 8 weeks with 100 larvae in each case three times a week. After the study period all lambs were slaughtered for post mortem investigation. The consumption of sainfoin hay over a period of 8 weeks was not associated with a reduction in FEC or in live weight performance. These results demonstrate no nematocidal effect of a tanniferous forage legume fed alone over 8 weeks against H. contortus
