Epidemiology of G.I. Nematodes of Small Ruminants of Uttarakhand

This book contains the epidemiology bioclimatograph and anthelmintic assessment of gastrointestinal nematodes of sheep and goats of Uttarakhand. The results of epidemiology indicated that sheep and goats were infected with G.I. strongyles throughout the year in both tarai and hill regions of Uttarakhand with the highest prevalence being in rainy season. Bioclimatographs prepared can serve as prediction models to aid in devising management strategies against strongyles. Based on the epidemiological pattern of G.I. nematodes in sheep and goats it is suggested that they should be treated with anthelmintics once in May/June August/September and February/March. Both sheep and goats harboured predominantly Haemonchus parasites besides Trichostrongylus Oesophagostomum Strongyloides and Bunostomum - which exert negative effects on productivity of animals as suggested by increased weight gains and improvement in haemato-biochemical alterations post-treatment with anthelmintics. These epidemiological findings can thus be utilized in formulating an effective control programme against G.I. nematodosis.
