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

Abstract

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.

Key words: phytase transgenic corn; broilers; blood physiological and biochemical indexes; immune function
