　　Purpose: To detect the developmental toxicity of the embryo and fetus of Bamani pigs and various developmental indicators of fetal development, and provide reference data for the developmental toxicity study of Bamani pigs

　　Method: Measure the number, number of embryos, length and tail of 12 Pamamini sows with fetal death on the 30th, 40th, 50th, 60th, 70th, 80th, 90th, 100th, and 112th days of gestation? Do you want to check the diameter of the brain, internal organs, and bones after taking X-rays?

　　Result: Bamami pigs can distinguish the sex of the fetus in 40 days. Is it the basic development or formation of pregnancy, internal organs, and skeletal system? It provides different developmental indicators for different gestation periods of miniature pigs.

　　Conclusion: Bama piglets can be used as observation objects for embryo and fetal development. Toxicity test. The basic data obtained in this study can be used to evaluate the reproduction of exogenous compounds.
