| 摘 要： | 选取胎次相近、日龄相同的杜—长—大哺乳仔猪16窝,随机分为4组,中药Ⅰ、Ⅱ组和抗生素组在相同的基础日粮中分别添加中药饲料添加剂Ⅰ(4 kg.t-1)、中药饲料添加剂Ⅱ(4 kg.t-1)和金霉素(70 g.t-1)+杆菌肽锌(30 g.t-1),对照组仔猪只饲喂基础日粮.于仔猪断奶前3 d,断奶后1、4、7、14、28 d采血,对血液部分激素指标进行分析,研究中药饲料添加剂对断奶仔猪生长性能和内分泌功能的影响.结果表明:(1)2个中药组仔猪日增重提高,料重比和腹泻率降低.(2)断奶后1 d,各组仔猪血清皮质醇含量与断奶前相比升高,而三碘甲腺原氨酸(T3)和甲状腺素(T4)含量较断奶前降低;整个试验期间,2个中药组血清皮质醇含量始终较抗生素组和对照组低,T3、T4含量始终高于抗生素和对照组.可见,中药饲料添加剂能有效地防止早期断奶仔猪发生腹泻,降低仔猪血清皮质醇含量,提高T3、T4的含量,缓解仔猪应激,改善仔猪的生长性能.

| Abstract: | The effect of Chinese herb feed additives on growth performance and endocrine function in weaned piglets was reported in this paper.16 litters of D×L×Y crossbred sucking piglets in similar fetals and farrowing dates were randomly divided into four groups,three treatments were added with traditional Chinese herb feed additives Ⅰ(4 kg · t-1),traditional Chinese herb feed additives Ⅱ(4 kg · t-1) and chlortetracycline(70 g · t-1) and bacitracinzinc(30 g · t-1) in the same basal diet,respectively.The blood samples were taken from the vena cava at 3 days before weaning and 1,4,7,14, 28 days post weaning.The results were as follows:(1) daily weight gains in two supplemental Chinese herb feed additives groups were increased,the feed conversion ratio and diarrhea rate were decreased,(2) a day after weaning,the serum level of cortisol in piglets decreased and the serum levels of triiodothyronine (T3) and thyroxine(T4) increased;Compared with antibiotics group and control group,the serum levels of cortisol in piglets in two Chinese herb groups were lower and the contents of serum T3 and T4 were higher during experimental period.From above results,it could be concluded that Chinese herb feed additives Ⅰand Ⅱ could prevent weaned piglets diarrhea and improve day weight gain and feed conversion ratio.It also could decrease the serum level of cortisol and increase the serum levels of T3 and T4 in weaned piglets. |
