摘要
内服亚硒酸钠对雏鸡的急性毒性,即LD50按每公斤体重计为20.65mg;按剂量定期递增染毒法给药,蓄积系数(k)=2.58,即1<k<3,表明为明显蓄积;
Acute and accumulative toxicities of sodium selenite in chicks were studied. The results showed that the LD 50 of sodium selenite to chick is 20.65 mg/kg of body weight. Medicine was given orally with graded increasing doses. The accumulation coefficient (K) equals 2.85, that is more than 1 and less than 3, which means significant accumulation. The chicks showed no tolerance to sodium selenite.
