sed drug being tested by two doses(therapeutic dose and a double therapeutic dose), as the following: (125, 250)ppm, respectively .The experience birds that braved /120/ chick at aged one day were divided to three equal distribution groups (Control, group(1), Sulphaquinoxaline, group(2) at concentration(125)ppm, Salafaquinoxaline, group(3) at concentration(250)ppm). The experience period continued for(45) days. The anticoccidial drug were presented continuously with fodder, and the blood samples were collected three times during this period.
