Four sheep were fed from automatic continuous feeders on whole barley fortified with graded levels of a urea solution. This approach was to a large extent successful in maintaining relatively steady states of rumen ammonia concentration. 2. Rates of barley fermentation in the rumen at various rumen NH3 concentrations were assessed by measuring the disappearance of barley dry matter from polyester bags suspended in the rumen of these sheep. 3. The minimal NH3 concentration for maximal rate of fermentation was estimated as 235 mg/l rumen fluid.

用自动连续喂食器给四只绵羊投喂添加了不同浓度尿素溶液的整粒大麦。这种方法在很大程度上成功维持了瘤胃氨浓度的相对稳定状态。2. 通过测量悬浮在这些绵羊瘤胃中的聚酯袋中大麦干物质的消失量，评估了不同瘤胃氨浓度下瘤胃中大麦的发酵速率。3. 发酵最大速率时的最低氨浓度估计为每升瘤胃液235毫克。
