摘　　要：在生长猪低钼低硒基础饲粮内,分别添加0、10、100ppm钼(钼酸铵),测定了猪肝、肾组织亚硫酸氧化酶活性、尿中SO_3~2-/SO_4^(2-)以及尿中SO_3^(2-)和SO_4^(2-)日排出量。结果初步表明:加钼能提高组织亚硫酸氧化酶活性,减少尿中SO_3^(2-)排出,提高SO_4^(2-)排出,降低尿中SO_2^(2-)/SO_4^(2-)。肝脏亚硫酸氧化酶活性与尿中SO_3^(2-)/SO_4^(2-)和SO_3^(2-)排出呈显著的强负相关,肾脏亚硫酸氧化酶活性与尿中SO_4^(2-)的排出量呈中等正相关。Three levels of dietary molybdenum (0, 10, 100ppm Mo as (NH_4)_6Mo_7 O_(24)·4H_2O) were supplemented in the selenium-deficient and molybdenumlow basic diet in Pigs. Hepatic and renal sulfite oxidase (SO) activity, urine sulfite/sulfate and sulfite, sulfate excretion via urine were determined. The results showed that the addition of molybdenum to the diet could increase both hepatic and renal SO activities, and daily urine sulfate excretion, but decrease daily urine sulfite excretion and sulfite/sulfate. There were significantly strong negative correlations between hepatic SO activity and urine sulfite/sulfate, and daily urine sulfite excretion. Renal SO activity was positvely correlated with daily urine sulfite excretion.
