Comparative Efficacy of Anticoccidials on Clinical, Gross and Histopathological Changes in Induced Broiler Caecal Coccidiosis

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). Poultry meat is considered to be an important source of animal protein both in rural and urban areas owing to their relatively low fat and cholesterol contents than other meat (Umaya, 2014; Senapati et al., 2015; Singh et al., 2015). In intensive poultry farming, birds are exposed to several stress factors which enhance their susceptibility to various diseases that are already existing or emerging. Amongst the diseases, coccidiosis is a widely known, greatly studied and yet incompletely understood protozoan diseases of poultry. These protozoa inhabits the caeca and adjacent intestinal tissues causing a severe disease characterized by bleeding, high morbidity and mortality, low weight gain, emaciation and other signs attributed to coccidiosis (Muthamilselvan et al., 2016).
