摘要

Ionophores have been widely used in the beef and dairy industry for decades to improve feed efficiency and performance by altering ruminal fermentation dynamics, increasing the level of propionate. Ionophores can also reduce ruminal proteolysis and ammonia synthesis, thus increasing the influx of protein into the small intestine in cattle, leading to improvements in performance and efficiency responses. Ionophores indirectly impact ruminal methanogenesis by decreasing the substrate used to produce methane. Despite the consistent benefits of using ionophores in cattle nutrition, their utilization is under public scrutiny due to concerns related to microbial adaptation. However, there is inconsistent evidence supporting these concerns, whereas ionophores are still an important dietary tool to enhance productivity and profitability in beef production systems.

牛肉和乳品行业广泛用于牛肉和乳制品，几十年来，通过改变瘤胃发酵动力学来提高饲料效率和性能，提高丙种水平。离子群还可以减少瘤胃蛋白水解和氨合成，从而将蛋白质的涌入量增加到牛的小肠中，从而提高性能和效率反应。通过减少用于生产甲烷的基材来间接地冲击瘤胃内甲烷。尽管在牛营养中使用离子团的一致益处，但由于与微生物适应相关的疑虑，它们的利用率受到公开审查。然而，存在支持这些问题的证据不一致，而离孔仍然是一种重要的饮食工具，以提高牛肉生产系统的生产力和盈利能力。
