Multi-species grazing is often advocated as a means to dilute nematodes in a pasture. Researchers in the French West Indies conducted a trial to investigate the specificity of Haemonchus contortus (barber pole worm) for goats and cattle and to evaluate cross-infection between the ruminants.
The effect of an experimental infection of 12 heifers by the free-living stages of H. contortus collected from goats (500 larvae per kg live weight) was evaluated and compared to uninfected controls. After 28 and 35 days, egg excretion was measured. The experimental infection of heifers by H. contortus was not significant, with no egg excretion.
These results (lack of cross-infection of GIN between goats and cattle), suggest that integrated grazing using such animals could be employed for pasture dilution and decontamination.
