ABSTRACT

The major pathogenic effect of gastrointestinal (GI) nematodosis is caused due to the protein loosing gastroenteropathy and blood sucking habit of some nematodes. The study involving 30 Garole sheep above four months of age naturally infected with gastrointestinal nematodes was conducted for estimating the haematological and economic impact in terms of meat production loss due to naturally occurring gastrointestinal nematodosis in field condition. Thirty sheep having natural infection of Haemonchus, Oesophagostomum, Trichostrongylus, Strongyloides,Trichuris and hookworm were randomly divided into two equal groups (n=15) – first group (Gr. I) was kept nematode free by tactical treatment with ivermectin @ 0.2 mg kg-1 body weight subcutaneously and the second group (Gr. II) was kept as untreated control. Haematological parameters i.e., haemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC) and total leucocytes count (TLC) in both the groups were estimated once prior to the first anthelmintic treatment (day 0) and thereafter on 10th, 40th and 70th day post treatment (DPT). The nematode infected sheep had significantly lower values of haematological parameters (except- TLC) compared to the nematode freed group of sheep. Body weight of all the sheep under study were recorded at monthly interval for 6 months and the net loss in terms of rupees was calculated by taking into account of final difference of mean body weight between the infected and parasite free groups, dressing percentage of sheep (50%), cost of treatment per sheep and the average rate per kilogram of mutton (Rs. 150.00) in West Bengal. The mean loss of body weight due to gastrointestinal nematodosis was 1.80 kg with a net loss of 0.90 kg mutton production in infected group. The average cost of treatment was Rs. 5.82 during the entire study period and the resulting economic loss was Rs. 129.18.
