Description Occurrence of gastrointestinal parasites in domesticated yaks of North and East districts of Sikkim was studied during the year 2001 to 2008. Of the 4,792 animals examined, 991 (20.68%) were found positive for different gastrointestinal parasites. The overall occurrence of different parasites recorded was strongyles (17.36%), Strongyloides spp. (4.34%), coccidia (4.55%), Toxocara spp. (2.25%), Trichuris spp. (2.88%), amphistomes (0.52%) and Moniezia spp. (3.07%). The infestation was more in Sub-Alpine low humid area (29.34%) as compared to Alpine dry zone ((19.0%) and Cold Desert zone (10.05%). The faecal egg counts (eggs per gram, epg) of nematodes ranged from 100 to 2 900, with higher loads during rainy and post-rainy seasons. The infection was higher in calf (1–5 months) and the parasites mostly recorded were Haemonchus spp., Toxocara spp. and Eimeria spp. The seasonal distribution of parasitism indicated a higher percentage of infestation in autumn (26.02%) and summer (21.57%) as compared with spring (20.65%) and winter (13.73%). On coproculture of positive samples, the nematode infestations in order of prevalence were Haemonchus, Bunostomum, Oesophagostomum and Nematodirus spp.
