Reduced glutathione (GSH) levels of erythrocytes were determined in high (GSHH) and low (GSHh) types of Finn sheep. The blood samples were drawn parallelly from jugular and mammary veins before and after milking to calculate arteriovenous differences across the mammary gland. Erythrocyte GSH levels were higher in jugular veins compared with respective mammary veins. This difference was markedly higher in high-GSH ewes. The arteriovenous difference was highest after milking. The ewes showing higher arteriovenous differences in erythrocyte GSH (high-GSH sheep) produced more milk during the first eight weeks of lactation. The results clearly indicated that erythrocyte GSH is involved in milk synthesis.
测定了高谷胱甘肽（GSHH）型和低谷胱甘肽（GSHh）型芬兰绵羊红细胞中还原型谷胱甘肽（GSH）的水平。在挤奶前后，分别从颈静脉和乳静脉平行采集血样，以计算乳腺的动静脉差异。颈静脉中的红细胞GSH水平高于相应的乳静脉。这种差异在高GSH母羊中明显更高。挤奶后动静脉差异最大。红细胞GSH动静脉差异较高的母羊（高GSH绵羊）在泌乳的前八周产奶量更多。结果清楚地表明，红细胞GSH参与了乳汁合成。
