Abstract
The present study reports about the intestinal coccidiosis in a commercial rabbit farm. Seven New Zealand white rabbits were died in a commercial rabbit farm in Tirupati during the month of August. All the rabbits had signs of anorexia, diarrhea, dullness and weakness. Rabbits were necropsied and collected the intestinal contents for laboratory examination. Up on post mortem examination, hyperemic and oedematous intestinal mucosa was noticed. Oocysts of Eimeria spp. were detected in the faeces of all the rabbits. The collected oocysts were transferred into 2.5% aqueous potassium dichromate solution for sporulation. Faecal samples were examined by modified McMaster technique to determine oocyst counts which had ranged from 13,200 to 16,400. Keywords : Intestinal Coccidiosis, OPG, Rabbits, Sporulation.

Present study was conducted on the seven rabbits (New Zealand white rabbits) belongs to the 2-3 months of age which were died by exhibiting the signs of diarrhea and weakness from a comercial rabbit farm in Tirupati in the month of August
Summary
Coccidiosis is caused by intracellular protozoon parasites of the genus Eimeria and causes significant mortality in domestic rabbits. Coccidiosis is one of the most frequent and prevalent parasitic diseases, accompanied by weight loss, mild intermittent to severe diarrhea with faeces containing mucus or blood and results in dehydration, decreased rabbit breeding (Jithendran and Bhat, 1996). The intestinal coccidial species causes weight reduction, diarrhoea and mortality due to villi atrophy will lead to malabsorption of nutrients, electrolyte disbalance, anaemia, hypoproteinemia and dehydration (Karaer 2001). The rabbit intestinal coccidia parasitize distinct parts of the intestine and in different depths of the mucosa (Pakandl, 2009).The causal agents of rabbit coccidiosis develop direct life cycle multiplying very fast and leading to massive infection, especially in young rabbits (Gres et al, 2003; Pakandl, 2009). The present report is on intestinal coccidiosis in young rabbits in an organized farm
