对来自45个繁殖性能差的日本黑牛（JB）种牛进行代谢谱试验（MPTs），结果表明，一个代谢谱异常的牛群在分娩期间饲喂过量的蛋白质饲料。粗蛋白质的饱满率为229%;作为饲料品质改善措施，粗蛋白质降低1 kg/d（相当于粗蛋白质需要量的202%）。6个月后，我们对总共10头奶牛进行了另一次MPT，并比较了饲料改进前后、产后开放期和生殖障碍发生前后的结果。并对犊牛疾病的发生发展情况进行了比较。在饮食干预前（n=9），血尿素氮（BUN）、总蛋白（TP）和白蛋白（Alb）水平在参考范围内，但葡萄糖（Glu）水平低于参考范围，3-羟基丁酸（3-HB）水平高于参考范围。膳食干预后（n=10），BUN、TP和Alb水平均在参考范围内，但TP水平显著升高（P
Metabolic profile tests (MPTs) in Japanese Black (JB) breeding cattle from 45 herds with poor reproductive performance revealed that one herd with an abnormal metabolic profile was fed excessive protein diet during parturition. The fullness rate of CP was 229%; as a feed quality improvement measure,the CP was reduced by 1 kg/day (equivalent to 202% of CP requirement). We performed another MPT six months later on a total of 10 cows,and compared the results before and after feed improvement, postpartum day open period, and occurrence of reproductive disorders. The occurrence and developmental conditions of diseases in the calves were also compared. Blood urea nitrogen (BUN), total protein (TP), and albumin (Alb) levels were within the reference range, but glucose level (Glu) was lower and 3-hydroxybutyric acid (3-HB) level was higher than the reference range before dietary intervention (n=9). After dietary intervention (n=10), BUN, TP, and Alb levels were within the reference range, but TP level increased significantly (P
