  <dc:description>本研究旨在调查围产期 BCS 缺失对奶牛产后性能和健康结果的影响。随机选择156头奶牛，在产犊后-21天、0天、7天、14天、21天、28天和50天采集血样。这些奶牛基于过渡期间的身体状况评分 （BCS） 损失：维持 BCS 损失组（M，0 &amp;lt; BCS 损失 &amp;le; 0.25）、低 BCS 损失组（L，0.25 &amp;lt; BCS 损失 &amp;le; 0.5）和高 BCS 损失组（H，BCS 损失 &amp;gt; 0.5）。H、M和L组的BCS下降（P &amp;lt; 0.01）。此外，与M组和L组相比，H组奶牛的非酯化脂肪酸、&amp;beta;-羟基丁酸、总胆固醇、天冬氨酸氨基转移酶、白蛋白、丙二醛和瘦素（P &amp;lt; 0.05）水平更高。相反，与M组和L组相比，H组的总抗氧化能力以及胰岛素和葡萄糖水平显着降低（P &amp;lt;0.05）。血浆中矿物质、尿素氮和总胆红素浓度不受BCS丢失的显著影响（P &amp;gt; 0.05）。此外，与H组相比，M组的奶牛患病的可能性较小。然而，H组奶牛的产奶量低于M组和L组的奶牛（P &amp;lt; 0.05）。这些观察结果共同表明，BCS损失与过渡期能量平衡、肝功能、氧化应激、产奶量和疾病发病率的可测量变化有关。</dc:description>
