Abstract：This experiment aims to study and analysis the feed additives widely used on the mar-ket, and discuss the effect of feed additives accumulation on growth and reproductive development of the second-feed male pups. 12 one-month-old male pups were select to randomly divided into ex-perimental and control groups. The control group was fed the normal diet and rat meat. The experi-mental group was fed the normal diet and high-dose rat meat. After the dogs mature, to test if high-dose rat meat could effect on male pups growth and reproductive development. Detected indica-tors of dogs serum hormone levels by using ELISA kits method. The results showed that: in experi-mental group the estradiol and follicle-stimulating hormone levels were significantly increased (P<0.01), testosterone levels significantly decreased (P<0.01), serm luteinizing was no signifi-cant change in high-dose group. Feeding rats can lead male pups endocrine hormones levels to be abnormal: 11-month-old male pups, estradiol and follicle stimulating hormone levels increased, testosterone level reduced. There was an impact on the reproductive development of male pups through interfering with the function of testicles in tip experimental groups of male pups fed rat meat.
