摘要

A total 431 faecal samples and 321 abomasii of goats from semi-arid region of India were examined and coproculture revealed 56.38% incidence of Haemonchus spp. The incidence was lower in summer season as compared to winter and rainy season. Abomasal examination of slaughtered goats showed 71.03% incidence of H. contortus worms with a range of 4-4.111 worms. Abomasal worm and faecal egg count were positively correlated and the correlation was significant. Female worms were more common than males withan average of 1.447 female/male ratio.
