对两种加工鱼肉中硒的营养效能进行了评价。用20%酪蛋白低硒饲料（0.046 μ g/g饲料）喂饲大鼠2周，然后在基础饲料中添加0.08 μ g/g硒（亚硒酸钠）、煮鲣鱼肉或干鲣鱼条，再喂饲8天。补硒引起大鼠肝脏硒浓度和谷胱甘肽过氧化物酶活性显著升高。虽然没有观察到显着差异，肝硒水平之间的大鼠喂养的硒补充饮食，肝酶活性的升高，饲料中补充鲣鱼饲料的大鼠只有45至53%的大鼠喂补硒的饮食。粪硒和尿硒的排泄量的饲料中添加鲣鱼喂养的大鼠高于硒管理的大鼠。这些结果表明，在鲣鱼肉中的硒的营养效率约为50%的亚硒酸盐和未知因素（S）以外的管腔吸收有助于低利用率的硒在鲣鱼肉。
The nutritional efficiency of selenium (Se) contained in two kinds of processed fish meat was appraised. Rats were fed on a 20% casein diet deficient in Se (0.046 micrograms/g diet) for 2 weeks, and were then fed on the basal diet supplemented with 0.08 micrograms/g of Se as sodium selenite, boiled meat of skipjack or dried strip of skipjack for an additional 8 days. The Se-supplementation caused a significant increase of the Se concentration and the glutathione peroxidase activity in the rat liver. Although significant differences in hepatic Se levels were not observed among the rats fed on the Se-supplemented diets, the elevation of the hepatic enzyme activities of the rats fed on the skipjack-supplemented diets was only 45 to 53% that of the rats fed on the selenite-supplemented diet. Amounts of excretion of both fecal and urinary Se of the rats fed on the diets supplemented with the skipjacks were higher than those of the selenite-administered rats. These results indicate that the nutritional efficiency of the Se in the skipjack meat is about 50% that of selenite and that unknown factor(s) other than luminal absorption contribute to the low availability of the Se in the skipjack meat.
