C肉毒杀鼠素对高原鼠兔的再遇适口性试验

Experiment on the Feed again Palatability of Botulin Type C as A Rodenticide to Ochotona curizoniae

目的：观察Ｃ肉毒杀鼠素对高原鼠兔的再遇适口性。方法：用霍恩氏法测定该制剂对试验动物的ＬＤ５０。结果：对照组摄食系数为０．７５，试验组摄食系数为１．０３。结论：该制剂的适口性极佳，是优良的生物灭鼠剂。

The experimen proved that the botulin type C as a rodenticide be highly palatable to plateau pika (Ochotona curizoniae),the coefficient of bait intake was 0.75.It was also highly palatable when feed again,the coefficient of bait intake was 1.03.The botulin type C is a very efficient biological rodenticide.
