It is very important to find out the reasons and the morphological changes of cattle abortion,death embryo and teratism in Sanjiang area, in order to determine the preventive measures, to improve animalquality, and to accelerate the animal industry. In the present studies, 25 cows and 25 local bos calves were in-vestigated. The powder of Veratrum nigrum L. and Euphorbia fischeriana steud, was medicated to the ani-mals during the 15 - 19th day of gestation. It was found that there were different poisoning reactions. Whenthe poisoning was on the 15 - 16th day of gestation, the pregnant animals were easy to miscarriage. When thepoisoning was on the 17 - 18th day of gestation, the embryos were easy to become teratism. The joint malfor-mation bicephalus and rachischisis could take place for calves. If the poisoning was after 19th day of gesta-tion, there were much more death embryos. The results of the studies showed that Veratrum and Euphorbiafischeriana steud, were the most poisonous plants to the animal industry of Sanjiang area. Some preventivemeasures were proposed.
