Salinomycin has a recomonded use lever of60 ppm in the diet to prevented the chicken coccidiosis.Abattery studies with two saiinoycin products (Eustin 100 and Premix salinomycin calcium ) were made. Twohundredand forty chickens were divided into four groups ,group Ⅰ with Premix salinomycin calcium ,group Ⅱ withE-100 ,group Ⅲ nonmedicated ,group Ⅳ uninfected and nonmedicate.From two days before oocyst administrationgroup Ⅰ and group Ⅱ began to feed the diet with drugs. Oocyst suspension(E. tenella 87%,E. maxima 3%,E.acervulina 10112× 10￣4/per chicken ) were administered to the each bird of groupⅠⅡ Ⅲ by gavage at 16days of age. Experiment were terminated 7 days p.i.,when all of the serviving birdswere sacrificed and examinedfor coccidial lesions. Cirteria ofinfection studied were:weight gains (WG),feed conversion(FC ),dropping scores(DS) lesion scores(L,number of oocyst per chicken(OPC) ,and mortalit.As the result ,group Ⅰ WG:262.42g,FC:2.08,DS:2.54,LS:8.42,group Ⅱ,WG:270.08,FC:2.03,DS:1.67,LS:09,groupⅢWG:118. 87,FC:3.86,DS :2.37,LS:7.6.There fore the Eustin 100 is better then premix salinomycin calcium.
