عنوان مقاله [English]
Coccidiosis is well known parasitic disease for the poultry industry worldwide. The disease causes a lot of economic losses by causing poor growth, feed efficiency and high mortality in the industry. Therefore, taking measures to prevent, diagnose, treat and control it become very important in farm management. The aim of this study is to qualitatively assess the Salinomycin efficacy against oocyte excretion in pullets by litter monitoring. To this end the litter samples were collected weekly during the growth period. Litter’s OPG was measured by McMaster and Eimeria species diagnosed using ocular micrometer and stage micrometer. Species identification carried out by morphometric indices of 154 oocysts. Basen on which four species of the Eimeria were identified, including Eiemeria acervulina, Eiemeria tenella, Eiemeria maxima and Eiemeria necatrix. E. maxima has the highest frequency and E. tenella had the lowest. According to this study Salinomycin prescription leads to the decrease in oocyst excretion and reduce the sporulation rate during pullets’ growth and Eimeria tenella oocysts showed the highest decrease following Salinomycin treatment. In this study, for the first time, salinomycin efficacy on the oocyst excretion was studied.
