    PREVALENCE OF GASTROINTESTINAL NEMATODOSIS IN CATTLE WITH SPECIAL REFERENCE TO Strongyles AND ITS THERAPEUTIC MANAGEMENT
    (College of Veterinary Science, Assam Agricultural University Khanapara, Guwahati-781022, 2016-12) Rai, Astuti; Kalita, D. N.
    The present study was conducted on prevalence of Gastrointestinal Nematodosis in cattle with special reference to Strongyles and its therapeutic management in different places of Assam, during the period from May 2015 to April 2016 for a period of one year with the objectives (i) to study prevalence of Gastrointestinal nematodes specially Strongyle infection in cattle, (ii) to study the haemato-biochemical changes in affected cattle and (iii) to find out comparative efficacy of some anthelmintics against Strongyle infection. A total of 1154 faecal samples collected from cattle of different places of Assam, were examined for detection of nematodes eggs, of which 271 cattle resulted positive for nematode eggs and the overall prevalence was recorded as 23.46 per cent. Out of 23.46 per cent, the percent prevalence of different nematodes i.e. Strongyle spp., Strongyloides spp., Trichuris spp. and Toxocara vitulorum were recorded as 9.27, 1.55, 1.99 and 10.65 per cent respectively. The season-wise prevalence was found to be highest (13.62 %) in monsoon season and lowest (5.47%) in pre-monsoon season. The highest prevalence of 15.23 per cent was recorded in cattle below 1 years and lowest prevalence of 5.35 per cent was recorded in cattle of 3 year above. A significant difference (P<0.05) in the variation in season-wise and age-wise prevalence was revealed The sex-wise prevalence was higher (10.46%) in female cattle than in male (7.73%).The breed-wise prevalence higher (10.59%) in local cattle than cross-bred (7.31%) cattle. There were no significant (P>0.05) difference in variation of sex and breed-wise prevalence. Out of the Strongyle positive cattle, 18 cattle, irrespective of breed, age and sex, were selected randomly and divided into 3 groups viz., Grpup I, Group II and Group III, each consisting 6 cattle. Another 6 healthy cattle were kept as healthy control and named as Group IV. In group I, cattle were treated with albendazole at the dose rate of 7.5 mg/kg body weight .orally for single dose, in group II, cattle were treated with ivermectin at the dose rate of 0.2 mg/kg body weight subcutaneously for single dose and in group III, cattle were treated with fenbendazole at the dose rate of 7.5 mg/kg body weight for single dose. Supportive therapy with mineral mixure (Minfa powder), antidiarrhoel (Diaroak) and 5 % dextrose were given to all the cattle in group I, II and III. During pre-treatment period, the haemato-biochemical study revealed a significant decrease in the levels of Hb, PCV, TEC, Lymphocytes and Monocyte in the affected cattle which increased gradually after anthelmintics treatment whereas an increase in the levels of TLC, Eosinophils and Neutrophils were observed in the affected cattle which also decreased gradually after treatment and reached normal level Based on reduction of EPG count, haemato-biochemical changes and recovery from clinical signs, the therapeutic efficacy was found to be highest (91.53%) with albendazole followed by fenbendazole (86.93%) and ivermectin (82.78%) in this study.
