Studies on the efficacy of diclazuril alone and in combination with turmeric powder and vitamin K on caecal coccidiosis in broiler chicks
Abstract
The studies on the efficacy of diclazuril alone and in combination with turmeric powder and vitamin K on caecal coccidiosis in broiler chicks was
viii
conducted in the department of veterinary parasitology, CCS HAU, Hisar. A total of 90, day old, broiler chicks were divided randomly into nine groups of 10 birds each. These birds were provided with diclazuril @ 1.0 ppm in feed, turmeric powder @ 7.0 g/ kg in feed and vitamin K @ 1g/ 150 lit of drinking water for 14 days, starting from day 15 of age till the age of day 28. These medicaments were provided alone as well as in combination. Afterwards, the birds were infected artificially with Eimeria tenella infection. The effect was monitored in terms of mean weight gain, oocyst index, hematology, serum protein profiling, mortality, global index and histopathological studies. The birds medicated with diclazuril performed better in terms of mean weight gain, oocyst output, oocyst index and lesion scores whereas the results were not encouraging when turmeric or vitamin K were provided alone. The hematological finding were recorded to be improved for turmeric and vitamin K groups, though no such obvious effects were observed for serum protein profiling and histopathological examination. On the basis of global index percentage, diclazuril was found to be an effective anticoccidial. However even more exaggerated anticoccidial efficacy of diclazuril was observed when conjuncted with turmeric and vitamin K. There was tremendous reduction in the mortality of all the medicated birds during the experiment.
