摘要:

分娩后奶牛发生子宫炎症的概率高达40%,子宫炎引发的不孕症是制约奶牛业生产效率的主要因素之一,造成了巨大经济损失。对于子宫炎的治疗主要有传统的子宫内灌注给药和系统给药方法。近年来,气囊子宫冲洗法逐渐被应用,其利用专用子宫冲洗管,将气囊置于奶牛子宫,注入液体冲洗子宫后,人工把液体及炎性物质全部排出,冲洗干净后投药。本研究利用323头被诊断为子宫炎的奶牛,进行气囊法与常规法治疗效果、气囊所放位置和冲洗用药对治疗效果的影响研究。结果表明,与常规法相比,气囊子宫体冲洗法提高了子宫炎奶牛的配种率,气囊法配种率达60%以上,而常规法配种率仅为35%左右。气囊子宫体冲洗法治疗效果明显优于子宫角放置法,气囊子宫体冲洗法配种率达60%以上,而气囊子宫角冲洗法治疗后其配种率仅为40%左右,且子宫体冲洗法节省时间、易于操作,安全系数高。3种药物组合都取得明显效果,生理盐水+土霉素子宫注射剂法的配种率达70%以上,露它净+宫得康法的配种率达60%以上,只用生理盐水冲洗的配种率也达55%以上。因此,与子宫内灌注给药、气囊子宫角放置冲洗等方法相比,气囊子宫体冲洗法显著提高了子宫炎奶牛的配种率,适用于在规模化生产中进行应用。这一新方法的推广对提高奶牛生产效率具有重要意义。

Abstract:

Uterine disease after parturition is present in up to 40% of dairy cows and can cause cow infertility,which restricts efficiency of the cow production and leads to large economic loss.System administration and intrauterine infusion are widely utilized to treat cow endometritis.In recent years,the balloon technique is used gradually.Uterus washing pipe is used to inject liquid into the uterus and then the liquid and the inflammatory substances are discharged by the veterinarian.After the inflammatory substances cleaning up,the drug is delivered into the uterus.In order to provide a new method that can treat the infertility in dairy cows with metritis,323 cows which were diagnosed with metritis were used to detect the efficiency of balloon technique,the location of the balloon and the different drugs perfusion against infertility in dairy cows with metritis.The results showed that the balloon technique was showed remarkable effect against cow metritis comparing to the conventional technique.The pregnancy rate of the balloon technique was more than 60%,by contrast,the conventional technique was about 35%.Compared with being placed in the cornua uteri,the efficacy was more obvious when the balloon was placed in the uterine body,and the pregnancy rate was more than 60%.However,the pregnancy rate of another method was almost 40%.There were prominent curative effect of the three drug combinations.The pregnancy rates of the saline+Oxytetracycline,Lutajing+Gongdekang and saline were more than 70%,60% and 55%, respectively.Therefore,compared to the conventional technique and cornua uteri technique,balloon technique(uterine body)significantly increases the pregnancy rate,which is beneficial to be widely used in production.So it is significant that the new technique used widely is important for improving the production efficiency of dairy cows.
