Abstract :

In this study, 380 broilers were investigated from the view point ofprevalence and histopathological changes of coccidiosis and coccidiasis inmahabad. The prevalence of coccidiosis and coccidiasis was determined 6.9in 100000. In parasitological investigation, frequency of oocystes in wetslide method and floatation were 17.1 % and 36.3 % and the frequency ofcoccidiasis, coccidiosis and total frequency of parasitic enteritis were 26.3 %, 10 % and 36.3 % respectively. In histopathological investigation thefrequency of mucosal edema, sub mucosal edema, hemorrhage, enterocytehyperplasia, necrosis, oocyste observance in mucus and inflammatory cellinfiltration were 74/2 %, 45/3 %, 25/3 %, 30/8 %, 27/1 %, 10 % and 18/2 %respectively. The high frequency of coccidiasis and coccidiosis after 4 and 7weeks were 21 % and 42/1 % respectively. It was also found that there is adirect relationship between parasitical enteritis and food convertion rate andtherefore meat production from food shows a bit decline. A meaningfulrelationship between different segment of intestine and parasitical enteritiswas found that one of the Eimeria species produced enteritis in theduodenum. The statistics methods of analysis in this study have been doneby SPSS soft ware.
