口服理囊散治疗排卵延迟奶牛的B超影像学的研究

Study on B-Mode Image of Ovulation-Delayed Dairy Cows after Taking Orally Cyst-Regulating Powder

为了进一步研究口服理囊散对排卵延迟奶牛机理的影响,试验对口服理囊散前后卵巢和子宫的形态变化进行了B超检查。在直肠检查结合B超对排卵延迟奶牛做出诊断后,口服理囊散,应用B超对排卵延迟奶牛的卵泡直径、卵巢长度、卵巢宽度、子宫角纵径和子宫颈纵径每3d测量1次。结果显示,30头排卵延迟奶牛口服理囊散后,治疗有效率头数24头,治疗有效率为80%。排卵延迟奶牛在口服理囊散结束后成熟卵泡破裂并排卵;口服中药后卵巢的长宽和口服前相比无统计学意义(P>0.05),但均达到了正常卵巢的大小;子宫角纵径在口服理囊散后第7、10、13天与口服前比较下降有统计学意义(P<0.05),子宫颈纵径在口服理囊散后与口服前比较无统计学意义(P>0.05);这说明理囊散对排卵延迟奶牛卵巢和子宫具有一定的影响,对治疗排卵延迟奶牛有一定的效果。

Some morphological indices of ovaries and uterus were detected through the B-mode ultrasound scanning to investigate the effects on mechanism of Cyst-regulating Powder to ovulation-delayed dairy cows.The cows were diagnosed by rectal examination combined with B-mode ultrasound scanning,and treated with the powder.The morphological indices including diameter of follicule,ovarian length and width,longitudinal diameter of cervix and horn uterus were counted every 3d by ultrasound scanning.The results showed that 24 out of 30 cows were treated effectively after taking Cyst-regulating Powder,with the effective treatment ratio 80%.80% of ovulation-delayed dairy cows appeared estrus and their mature follicule ruptured and ovulated on next estrus cycle.The changes of morphological indices of ovaries before and after taking medicine were not significant（P0.05）,but all reached normal ovarian size.The changes of longitudinal diameter of horn uterus were significant on 7d,10d and 13d after the treatment（P0.05）;the differences were not significant（P0.05）.Conclusion：Cyst-regulating Power had obvious effects on the treatment of ovulation-delayed dairy cows.
