摘要: 本试验旨在研究柴术抗激散对早期断奶仔猪生产性能和血清应激相关激素水平的影响。选用(28±2)日龄"杜×长×大"断奶仔猪48头,随机分为4个处理组,每个处理组3个重复,每个重复4头猪,分别饲喂添加0、1%、2%、3%柴术抗激散的日粮,试验期28 d。结果显示,日粮中添加2%和3%的柴术抗激散能显著提高断奶仔猪的平均日采食量和平均日增重(P<0.05),显著降低料重比(P<0.05),极显著降低腹泻率(P<0.01),可显著降低35和56日龄仔猪的血清皮质醇水平(P<0.05),显著提高35和56日龄仔猪血清生长激素、胰岛素、三碘甲状腺素、胃泌素水平(P<0.05)。由此可知,日粮中添加柴术抗激散可有效缓解断奶应激对仔猪造成的伤害,且在日粮中添加2%的柴术抗激散效果最好。

Abstract: To study the effects of Chaizhukangjisan on growth performance and the levels of stress related hormones of serum in early-weanling piglets, 48 'Duroc×Landrace×Yorkshine’ crossbred early-weanling piglets in (28±2) day age were randomly divided into 4 treatments of 12 piglets each, with three replicates in each group and 4 piglets in each replicate, and fed with basal diet, basal diet plus 1%,2% and 3% Chaizhukangjisan respectively. The experiment lasted for 28 d. The results showed that adding 2% or 3% Chaizhukangjisan could significantly improve the average daily gain and the average daily feed intake of weanling piglets (P<0.05),significantly decrease the ratio of feed to gain (P<0.05) and post weanling diarrhea rates(P<0.01),significantly decrease the level of serum COR in the age of 35 and 56 d, and significantly improve the levels of Serum GH, INS, T4 and GAS in the age of 35 and 56d. Chaizhukangjisan could efficiently relieve the weanling stress on piglets. In production practice, adding 2% Chaizhukangjisan in basal diet could obtain the best effect.
