摘　　要：酮病作为一种奶牛围产期易发的营养代谢疾病,导致其生产性能急剧下降,严重损害牧场经济效益。在消化过程中,健康胃肠道环境发挥至关重要的作用。目前研究表明,患有酮病的牛只胃肠道环境,包括胃肠道形态结构、菌群组成及瘤胃液组成成分等均会发生明显变化,而奶牛围产期间胃肠道环境的不同变化又会影响酮病发生概率,二者相互影响。据此,建议更加深入研究奶牛胃肠道菌群与酮病之间关系,为酮病的预防及治疗提供新思路。Ketosis is a nutritional and metabolic disorder that commonly affects dairy cows during the perinatal period.It can result in a sharp decline in production performance and have a serious impact on farm economics.Current research indicates that maintaining a healthy gastrointestinal environment is crucial for the digestive process.In dairy cows with ketosis,significant changes occur in the gastrointestinal environment,including the morphology and structure of the gastrointestinal tract,the composition of the bacterial flora,and the composition of the rumen fluid.These changes not only predispose dairy cows to ketosis,but also influence its occurrence in normal dairy cows.Consequently,studying the relationship between gastrointestinal microbiota and ketosis in dairy cows deeper offers new possibilities for preventing and treating ketosis.
