Effects of the use of heather as anthelmintic in goats infected with trichostrongylus colubriformis on ruminal fermentation and digestibility

Previous field studies have supported the absence of a nutritiocost outweighing the beneficial anthelmintic effect of supplementing the diet of grazing g oats with tannin-containing heather. In order to fur- ther research in this regard, an experiment was conducted indoors w ith 18 does artificially infected with Trichostrongylus colubriformis . The goats were offered lucerne hay for 6 weeks and then assi gned to 3 treat-
