Changes in liveweight gain, blood constituents and worm egg output in goats infected with a sheep-derived strain of Trichostrongylus colubriformis

Two groups of goats were dosed with 20,000 and 40,000 sheep-derived strain (SDS) larvae of Trichostrongylus colubriformis respectively. Over a period of 42 days, goats dosed with 40,000 larvae lost more weight than goats dosed with 20,000 larvae. Anaemia was not observed in infected goats, but total serum proteins, albumins and phosphorus fell with infection.
