Nitrogen (N) loss from livestock agriculture, via reactive compounds such as ammonia and nitrous oxide, can affect feed efficiency, production and the environment. An option for an on-farm strategy to reduce N loss is to add dietary supplements to the total mixed ration (TMR) including Yucca schidigera extract, which contains antimicrobial steroidal saponins and ammonia binding properties, and yeast, which has been reported to stabilise rumen pH and promote fibre degradation by the rumen microbiome.

畜牧业生产中，畜禽通过氨、一氧化二氮等活性化合物流失的氮（N），会对饲料利用率、生产性能及生态环境造成不利影响。一种可降低氮流失的农场端养殖策略，是在全混合日粮（Total Mixed Ration，TMR）中添加膳食补充剂：一类为丝兰（Yucca schidigera）提取物，其含有抗菌甾体皂苷且具备氨结合特性；另一类为酵母，据报道可稳定瘤胃pH值并促进瘤胃微生物群降解纤维。
