Abstract
  1. Regular removal of fluid from the mammary gland, before parturition, stimulated its secretion of triglycerides, and particularly C18 fatty acids in the triglycerides, in some individual cows. 2. Cows that did not respond to pre-partum emptying were stimulated to secrete triglycerides by parturition. 3. The onset of secretion of milk triglycerides correlated with the onset of secretion of mammary fluid. 4. No increase in the ratio of C18:1 to C18:0 in the triglycerides, reflecting an onset of mammary desaturase activity, was observed.
摘要
  1. 在分娩前定期从乳腺中抽取液体,刺激了一些个体奶牛乳腺中甘油三酯的分泌,尤其是甘油三酯中C18脂肪酸的分泌。2. 对产前排空无反应的奶牛,在分娩时受到刺激而分泌甘油三酯。3. 乳甘油三酯分泌的开始与乳腺液体分泌的开始相关。4. 未观察到甘油三酯中C18:1与C18:0的比例增加,这反映了乳腺去饱和酶活性的开始。
