| 摘 要： | 试验旨在研究转植酸酶基因玉米对肉仔鸡血液生理生化指标和免疫功能的影响。采用单因子完全随机设计,将160只1日龄AA肉仔公雏鸡分成2组,分别为对照组和试验组,每组10个重复笼,每个重复笼8只鸡。对照组饲喂非转植酸酶基因亲本玉米日粮,试验组饲喂转植酸酶基因玉米日粮,两组鸡在试验期间饲喂日粮中的可利用磷等所有养分含量均相等或相近。试验期为42 d,分为1~21和22~42日龄2个饲养阶段。结果显示,试验组与对照组相比,42日龄肉仔鸡的血液生理生化指标、免疫器官指数、血清新城疫抗体滴度和全血T淋巴细胞转化率均无显著差异(P＞0.05);21日龄肉仔鸡的血清新城疫抗体滴度也无显著差异(P＞0.05)。因此,转植酸酶基因玉米日粮对肉仔鸡未产生不良影响,可安全饲喂于肉仔鸡。

| Abstract: | This experiment was conducted to investigate the effects of phytase transgenic corn (PTC) diets on blood physiological and biochemical indexes and immune function of broilers. A single-factor completely randomized design was used. A total of 160 AA mail broilers (one-day-old) were randomly allotted by body weight to two treatment groups (ten replicate cages of eight chickens per cage). Broilers of the control group were fed with isogenic conventional corn (CC) diet, and broilers of the test group were fed with PTC diet. During the experiment,the concentrations of all nutrients (containing available phosphorus) in the diet of the two treatments were equal. The experiment had two phases (0 to 21 days and 22 to 42 days). The results showed that compared with the control group,there were no significant differences (P＞0.05) in blood physiological and biochemical indexes,immune organ indices, serum antibody titers,and T lymphocyte transformation rate at 42 d and serum antibody titers at 21 d. These results indicated that PTC diet had no adverse effects on the above parameters during the experiment period and might be safe for broilers to feed. |
