摘　　要：采用７日龄公雏进行三系列实验，对照组分别饲喂含大麦３１％，５０％和６６％的基础日糖，试验组在基础日粮中分别添加粗酶制剂０．２％，０．１％和０．１％，持续饲喂１４ｄ。结果表明，粗酶制剂添加于大麦基础日粮可显著提高雏鸡增重（Ｐ＜０．０５），且使其血清三碘甲腺原氨酸（Ｔ３）、促甲状腺激素（ＴＳＨ）显著升高（Ｐ＜０．０５），生长激素（ＧＨ）含量及Ｔ３／Ｔ４值有上升趋势，而对胰岛素（Ｉｎｓ）和甲状腺素（Ｔ４）含量的影响不显著。Three experiments were conducted to determine the effects of barley based diets supplemented with crude enzyme preparations on growth and some serum metabolic hormones contents in chicks. Sevendayold male chicks were given control diets (basal diets containing 31%, 50% and 66% barley, respectively) or enzyme treatment diets (basal diets same as above, supplemented with 0.2%, 0.1% and 0.1% crude enzyme preparations, respectively) for 14 days in each experiment. Basal diets supplemented with enzyme significantly increased body weight gains (P<0.05) and serum T 3 and TSH contents (P<0.05) in chicks. There were tendencies towards increase in blood GH contents and T 3/T 4 ratio in enzyme treatment groups. However, no significant difference in T 4 and insulin contents between treatment and control groups were observed. The results provided evidence that crude enzyme preparations can influence growth and endocrine functions in chicks.
