Avian coccidiosis, an intestinal disease caused by protozoan parasites of the genus Eimeria, occurs worldwide. It is considered to be one of the most economically important diseases of domestic poultry. For many years, prophylactic use of anticoccidial feed additives has been the primary means of controlling coccidiosis in the broiler industry and has played a major role in the growth of this i...

The relationship between oocyst dose and lesion score was evaluated in trials involving five field isolates each of Eimeria acervulina, Eimeria maxima, and Eimeria tenella. Each trial included an uninfected, unmedicated treatment, and at least three treatments of unmedicated birds given different doses of oocysts from a single isolate. In four trials each with E. acervulina and E. tenella, and ...

India is one of the largest and fastest poultry growing industry currently holding the third position in the world in egg production and poultry meat production has reached about 2.2 million tons per year (Maharana and Tewari, 2011).The Gujarat state is no more exception to this as the poultry population has increased by 12.39% from year 2007 to 2012 (Livestock census, 2012).

Disposition pharmacokinetic of tylosin concomitantly administrered with either diclazuril (Clinacox ) (1 ® mg/kg feed) and halofuginone (Stenorol ) (3 mg/kg feed) were studied following a single IV, oral and IM ® administrations in broiler chickens. Following IV injection, tylosin serum concentration was best to be 1⁄2 á described by a 2-compartment open model. Diclazuril resulted in a short di...

Coccidiosis control programs such as vaccines or in-feed anticoccidials are commonly practiced in the poultry industry to improve growth performance and health of commercial broiler chickens. In this study, we assessed the effects of various coccidiosis control programs (e.g., in ovo vaccination, synthetic chemicals, and antibiotic ionophores) on immune status of broiler chickens vaccinated aga...
