| 摘 要： | ８０只１日龄Ａｖｉａｎ鸡，随机人灵实验组和对照组，每组４０只，自１日龄开始，实验组鸡肌肉注射胸腺因子Ｄ（ＴＦＤ），剂量２ｍｇ／ｋｇ，对照组注射生理盐水，隔日注射，共５次。试验期４２ｄ，观察ＴＦＤ对肉鸡生长、免疫及血液中某些激素影响。表明１）注射ＴＦＤ可显著促进Ａｖｉａｎ鸡生长，２）２３日龄时实验组鸡的外周血Ｔ淋巴细胞百分率极显著高于对照组（Ｐ〈０．０１）。３）实验组在２８日龄时血浆甲状腺素（Ｔ４）

| Abstract: | Eighty day old chickens were randomly divided into two groups ( n =40). The treated group was injected via sternal muscle with thymic factor D at 3 mg/kg body weight every other day from day 1 to 10, while the control group was given the same volume of sterile 0.9% NaCl. All chickens were weighed once a week from day 14 on wards. Blood samples were collected and the concentrations of thyroxine (T 4). Trilodothyroxine (T 3) and growth hormone (GH) in the plasnas were measured by radioimmunoassay (RIA). The percentage of T cells were calculated on day and 23,38. The results showed that: 1) Injection with TFD promoted growth. 2) On day 23, the percentage of T cells between treated group and controe group was significantly different ( P <0.01). 3)The concentration of T 4 between the two groups was different ( P <0.05) on day 23. The concentrations of T 3 and GH of the treated group were higher than those of the control, but the difference was not significant ( P >0.05). |
