Comparative Effect of Doramectin and Fenbendazole in Management of Clinical Toxocariosis in Pandharpuri Buffalo Herd

Toxocariosis due to Toxocara vitullorum is a major parasitic problem among suckling and freshly weaned cattle and buffalo calves. The parasite is more pathogenic for buffaloes compared to cattle. Prenatal ( in-utero ) and postnatal (transcolostral) transmission of the larvae to the foetus or the suckling calves results in heavy worm burden that may be often fatal. A case of clinical toxocariosis was observed among one month old buffalo calves of Pandharpuri breed. Quantitative faecal examination revealed count of 2700 to 27,600 Toxocara eggs per gram of faeces. Calves were treated with doramectin and fenbendazole and the results were compared by recording faecal egg output (EPG) up to 21 days post treatment.
