摘要
选７周龄６００只罗曼蛋鸡随机均分５组，试验３组分别饲喂１０％，１５％，２０％“双低”菜籽粕日粮，对照２组分别饲喂全豆粕、８％普通采籽粕日粮，试期１３周（８～２０周龄鸡）。结果表明，１０％，１５％“双低”菜籽粕日粮对蛋鸡生长发育、饲料增重比、甲状腺及血清Ｔ＿３，Ｔ＿４，ＴＳＨ，Ｔ＿Ｇ，Ｔ＿Ｍ浓度、肝脏及血浆ＣＨＥ，ＧＯＴ，ＧＤＴ，ＡＫＰ活性无不良影响（Ｐ＞０．０５）；２０％“双低”菜籽粕日粮组鸡表现明显的生长抑制（Ｐ＜０．０５）．甲状腺肿大４４．２％（Ｐ＜０．０１），Ｔ＿３下降１６．３％（Ｐ＜０．０５），Ｔ＿Ｇ上升５４．５％（Ｐ＜０．０１），肝出血明显，血浆中ＧＰＴ，ＧＯＴ升高（Ｐ＜０．０５）
Six hundred growing chicken were randomly divided into five groups,3 of which were fed with basal diets,as the treatments,of 10%,15%,and 20% DL-RM(double low)from 8 to 20 weeks of age,and the other 2,as the control,fed with all soy-bean meal protein and 8% C-RM(common rapeseed meal).The results were:whenDL-RM contents vvere 10%,15%,no significantly ill effects were found in chicken'sgrowth,feed gain ratio,thyroid size,and the density of T_3,T_4,TSH,T_G,T_M in theserum,liver,activities of GOT,GPT,AKP,CHE in plasma compared with the controlgroup;when DL-RM contents were 20%,obviously ill effects of the growth retardation(P<0.05 ),goiter swallovved by 44.2%(P<0.01),T_3 dropped by 16.3%,T_G raisedby 54.5%(P<0.01),apparent liver bleeding,and GPT and GOT in plasma raised(P<0.05).
