摘 要:优素精 ̄(日本科研制药株式会社制品)和盐霉素(山东济宁抗生素厂制品)之抗球虫效力的比较试验。14日龄艾维因肉鸡分4组;Ⅰ、盐霉素组;Ⅱ、优素精组;Ⅲ、感染不给药对照组;Ⅳ、不感染不给药对照组。每组6笼,每笼10只(公母各5只)。优素精和盐霉素均以60ppm之浓度混合于饲料中,自由摄食。16日龄时,Ⅰ、Ⅱ、Ⅲ组分别经口感染E.acervulina,E.maxima和E.tenella混合卵囊,每鸡10.12×10 ̄4。23日龄(感染后7天)解剖全部鸡。依增重,饲料利用效率,血粪,卵囊排出量,球虫病变值和球虫病死亡率判断抗球虫效力。试验结果:优素精组的平均增重(270.08克)和饲料利用率(2.03)是试验各组中最优良的。比不感染不给药对照组优越,生物统计差异显著(P<0.01)。盐霉素组的平均增重(262.42克)和饲料利用率(2.08)虽高于不感染不给药对照组,但其差异不显著(P>0.05)。优素精组的球虫病变值比感染不给药对照组低46.40%,比盐霉素组低36.29%,卵囊排出量比感染不给药对照组低97.25%,比盐霉素组低20.04%。本试验证明,优素精有强烈的抗球虫药效,同时也证明有促进生长,加速增重?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.
