beta hydroxybutyrate (BHB) serum concentrations were measured at regular intervals throughout a lactation in groups of animals from three commercial dairy herds. The period of study covered all the major seasonal management changes. BHB levels changed significantly only when the dietary intake of the cows was altered either in quantity of quality. The changes in concentrations of serum BHB were of particular interest during the two grazing seasons when the deteriorating quality of the pasture was reflected in significantly higher concentrations. It is considered that serum BHB concentrations are worthy of further investigation as a parameter for inclusion in preventive medicine monitoring schemes for commercial dairy herds.
在三个商业奶牛场的动物群体哺乳期内，定期测量β-羟基丁酸（BHB）的血清浓度。研究期间涵盖了所有主要的季节性管理变化。仅当奶牛的饮食摄入量在数量或质量上发生改变时，BHB水平才会有显著变化。在两个放牧季节，血清BHB浓度的变化尤其令人关注，此时牧场质量下降反映在BHB浓度显著升高上。人们认为，血清BHB浓度作为商业奶牛场预防医学监测方案中的一个参数，值得进一步研究。
