In the present studies, 25 cows and 25 local bos calves were investigated. The powder of Veratrum nigrum L. and Euphorbia fischeriana steud. was medicated to the animals during the 15 - 19th day of gestation. It was found that there were different poisoning reactions. When the poisoning was on the 15 - 16th day of gestation, the pregnant animals were easy to miscarriage. When the poisoning was on the 17 - 18th day of gestation, the embryos were easy to become teratism. The joint malformation bicephalus and rachischisis could take place for calves. If the poisoning was after 19th day of gestation , there were much more death embryos. The results of the studies showed that Veratrum and Euphorbia fischeriana steud. were the most poisonous plants to the animal industry of Sanjiang area. Some preventive measures were proposed.展开更多
