奶牛产后子宫复旧不全的血清生化指标变化

Changes in serum biochemical indicators of postpartum uterus incomplete recovery in dairy cows

为了探究奶牛子宫复旧不全的血清生化指标变化情况,试验应用直肠检查与B型超声波检查奶牛产后子宫复旧情况,根据检查结果将29头试验奶牛分为A组(子宫复旧良好组,16头)、B组(子宫复旧不良组,13头),分析两组奶牛血中矿物质代谢指标、能量及肝脏功能代谢指标和生殖激素代谢指标的含量变化。结果表明:A组奶牛血清中钙、镁、葡萄糖、雌二醇含量均显著高于B组(P<0.05);B组奶牛血清中β-羟丁酸、总胆固醇、孕酮的含量显著高于A组(P<0.05)。说明奶牛发生子宫复旧不全与体内矿物质、能量和生殖激素的异常变化有关。

In order to explore the changes of serum biochemical indicators of postpartum uterus incomplete recovery in dairy cows,rectal examination and B-ultrasonic examination were used to check the postpartum uterine recovery in dairy cows.According to the results of examination,29 dairy cows were selected and divided into group A(16 cows with good uterine involution)and group B(13 cows with uterine involution)to analyze the content changes of mineral metabolism indicators,energy and liver function metabolism indicators and reproductive hormone metabolism indicators in the two groups of cows.The results showed that the contents of calcium,magnesium,glucose and estradiol in the serum of cows in group A were significantly higher than those in group B(P<0.05).The contents ofβ-hydroxybutyric acid,total cholesterol and progesterone in the serum of cows in group B were significantly higher than those in group A(P<0.05).It indicated that the uterine incompleteness of dairy cows was related to the abnormal changes of minerals,energy and reproductive hormones in the body.
