Abstract
- In three series of experiments, Na235so4 was infused into the rumen of sheep consuming a variety of diets. The specific activity of the sulphur in the rumen H2S pool, rumen bacteria and of the S in bacterial cystine were determined. 2. The results showed that, depending upon the diet, the proportion of total sulphur and cystine sulphur in rumen bacteria originating in the rumen H2S pool could be as low as 0-557 and 0-280 respectively.
摘要
- 在三组实验中，将Na₂³⁵SO₄注入食用各种日粮的绵羊瘤胃中。测定了瘤胃H₂S池、瘤胃细菌中硫的比活度以及细菌胱氨酸中硫的比活度。2. 结果表明，根据日粮不同，瘤胃细菌中源自瘤胃H₂S池的总硫和胱氨酸硫的比例分别可低至0 - 557和0 - 280。
