摘要
将1日龄银香鸡随机分成4组,即空白对照组、试验1、2、3组(分别添加0.03%益乐素、益生宝、欣益康),每组设两个重复,每个重复100只鸡,共800只。0～4周龄的试验结果试验1、2、3组4周龄体重分别为343g、364g和374g,分别比对照组的333g提高10g(差异不显著)、31g(差异显著)和41g(差异极显著);每kg饲养成本分别比对照组降低0.06元、0.47元、和0.57元;育雏成活率分别比对照组提高1.5、2.0和2.5个百分点。表明这三种微生态制剂均有不同程度的防病促长、改善饲料转化率、提高成活率和经济效益等作用。相互比较结果依次为欣益康优于益生宝优于益乐素。
Eight hundreds one-day-old Yingxiang-chicken were divided randomly into four groups, and every group had two repeat. Three groups(test1,2,3) were added 0.03% different probiotics in food(Yi-Le-Su, Yi-Sheng-Bao, Xin-Yi-Kang).
