摘要
测定了马杜霉素渣中铅、砷、镉、铬的含量及对小白鼠的毒性和对鸡的抗球虫性能。试验结果：马杜霉素渣中铅含量１．０５ｍｇ／ｋｇ，砷含量小于１．０ｍｇ／ｋｇ，镉含量１．２ｍｇ／ｋｇ，铬含量２６ｍｇ／ｋｇ；马杜霉素渣对小白鼠的ＬＤ５０为３５４．６５ｍｇ／ｋｇ，比马杜霉素毒性大。马杜霉素渣的抗球虫指数为１７３～１７５．１，属中等强度抗球虫药。以上结果表明，马杜霉素渣可以作为抗球虫药应用，但应用时要防止中毒的发生。
The contents of Cd, As, Pb, Cr in the Residues from Maduramicin(RM) were determined. Toxicity test and efficiency of anticoccidials trial were conducted to evaluate the efficiency of RM. The contents of Cd、As、Pb and Cr are 1.2, 1.0, 1.05, 26 mg/kg respectivily. LD50 of RM is 354.65 mg/kg. The toxicity of RM is higher thanthat of Maduramicin. The anticoccidial index(ACI) of RM was 173.0～175.1. being middle efficiency of anticoccidial. The results suggested that RM can be used as anticoccidial drug, but, one must be careful.
