摘要 选用20 kg左右的"冀合白猪"30头,分为对照组和试验组(Ⅰ组和Ⅱ组),试验组分别按1%和2%添加中药添加剂"增重灵",观察增重情况,测定血清中生长激素(GH)、三碘甲腺原氨酸(T3)、甲状腺素(T4)的含量.结果显示,试验组平均日增重(ADG)比对照组分别提高了20.1%(P<0.05)和27.6%(P<0.01),料重比(F/G)分别降低19.9%(P<0.05)和23.8%(P<0.05),GH含量分别提高3.7%(P>0.05)和23.0%(P<0.05),T3含量分别提高28.5%(P<0.05)和36.1%(P<0.01),T4含量分别提高19.3%(P<0.05)和32.8%(P<0.01).表明"增重灵"可以促进血清激素GH、T3、T4的合成和分泌,对生长猪具有显著的促生长作用. To investigate the effect of Chinese medicinal herb feed additives “Zengzhongling” on gowth performance and the content of GH, T3, T4in the serum of growing pigs, 30 growing pigs (20 kg initially) were divided into control group(no additive), treatment group Ⅰ (1% Chinese medicinal herb feed additives) and treatment group Ⅱ (2% Chinese medicinal herb feed additives). The results showed that comparing to control group,the treatment group Ⅰ and group Ⅱ were increased 20.1% ( P 〈0.05)and 27. 6% ( P 0.01) of the weight gain per pig perday, 19. 9% ( P 〈0.05)and 23.8 % ( P 〈0. 05)of the food efficiency, 3.7%( P 〉0.05)and 23%( P 〈0.05)of the content of GH, 28. 5%( P 〈0.05)and 36.1%( P〈0. 01) of the content of T3,19.3% and 32. 8% of the content of T4, respectively. The results indicated that the effect of the“Zengzhongling”on improving growing performance perhaps though the system of internal secretion.
