鸡渣蛋白质营养液的动物实验研究

An Animal Experiemtal Study on Protein Extracted from Chicken Residue

用从生产保健品过程中排弃的全鸡渣经水解提取的蛋白质制成液体，以不同剂量每天给大鼠灌胃一次，连续4周。结果高剂量组大鼠身长和体重增长、饲料效价（FE）和蛋白质功效比值（PER）、肝总氮和肝含氮率均与阳性对照组接近而大于阴性对照组；对大鼠脏器重量和脏器与体重比、血中血红蛋白含量则未发现有明显影响。显示其吸收利用和营养价值与纯正鸡精保健产品相似，值得提取利用。

Rats were fed one time per day for four weeks with protein liquid extracted from whole chicken residue in proceding of produceing health food, the results chicken residue in proceding of produceing health food, the results showed that in high does group, theincrease of the rat body height and weight, the feed efficiency(FE) and protein efficiency ratio(PER), the total hepatic nitrogen and the nitrogen rate of liver were all similar to the positive control control, but high than the negative control coutrol group; the liquid had no obvious effect on the weight of various organs, organ and body weight ratio and hemoglobin in rat, indicating that the absorption, utilization and nutrition of the liquid were similar ot that of the pure traditional essence of chicken. Therefore, the all results demostrated the chicken residual protein was worth extracting and utilizing for human health food.
