摘要
本实验在饲喂日本（Ｉ）与中国（Ｉ）两种不同日粮水平的条件下，观察了ＳＨＮ小鼠的生长发育并测定了体重、发情周期、主要器官重量、血糖、糖耐量、尿成分、癌前症状等多项生理指标。结果表明，饲喂两种饲料ＳＨＮ小鼠的生长发育没有明显差异（Ｐ＞０．０５），饲料Ｉ能更好保持ＳＨＮ小鼠的生物学特性，其乳腺癌自发率较高。尿中尿素、马尿酸、柠檬酸的含量也明显低于饲料Ｉ（Ｐ＜０．０５）。提示这种影响可能与饲料的营养成分有关。
The effects of Chinese diet (pellet) for mouse and rat (Institute of laboratory animal science of CAMS) on growth and several physiological parameters was examined in SHN mice in comparison with Japanese commercial pellet (LAB MRBreeder:Nihon nosna Kogyo KK).Some differences were found in body growth,pattern of estrous cycles,normal and preneoplastic mammary gland growth,major organ weights,serum glucose levels and glucose tolerance by using the two kinds of diet.The result indicate that the Chinese diet examined satisfies the fundamental demands for mouse,Spontaneous mammary tumorigensis tended to be higher and some components of urinary excretion were significantly lower fed by Chinese diet than that by Japanese diet.
