黄芩甙对断奶仔猪生产性能和免疫机能的影响研究

将96头杜×长×大三元杂交断奶仔猪随机分为4组,每组设3个重复。第1组为对照组,饲喂基础日粮;第2组在基础日粮中添加0.006%的喹乙醇;第3组在基础日粮中添加0.05%的黄芩甙;第4组在基础日粮中添加0.006%的喹乙醇和0.05%的黄芩甙,探讨黄芩甙与仔猪免疫机能的关系。结果表明:第2、3、4组血清中总蛋白I、gG水平与第1组相比有升高的趋势(P>0.05);第2、4组的白球比值显著低于第1组(P<0.05),3组白球比值也低于1组(P>0.05);第2、3、4组T3、C4、GH水平显著高于第1组(P<0.05),而C3、T4水平有升高的趋势,但差异不显著(P>0.05),皮质醇含量显著低于第1组(P<0.05)。试验结果表明,在早期断奶仔猪日粮中添加黄芩甙具有改善免疫机能的作用,有助于提高仔猪抗病力。

Study of Baicalin on Immune Function in Weaning Piglet

96 weaning Duroc×Landrance×Large piglets were randomly divided into 4 groups with 3 repeats in every one.The piglets were fed basal diet,basal diet+0.006%antibiotic,basal diet+0.05%Baicalin,basal diet+0.006%antibiotic+0.05%Baicalin in group1(control),2,3,4 respectively.The result showed that the level of TP and IgG in serum of group2,3,4 has an enhanced trend(P > 0.05).The number of ALB/GLO of group2,4 was lower than that of group1 significantly(P < 0.05),group 3 was also lower but not nsignificantly(P > 0.05).And the level of T3,C4,GH of group2,3,4 was enhanced(P < 0.05),C3,T4 was also increased(P > 0.05),and the Cor was decreased compared with GroupⅠ(P < 0.05).
