奶牛乳房炎是危害奶牛养殖业最常见且难以防治的疾病之一。目前,全世界约有奶牛2.2亿头,其中约有1/3的奶牛患有各种类型乳房炎,每年因乳房炎造成的损失高达350亿美元,仅美国的损失就达20亿美元。目前,通常采用抗生素进行治疗,但效果不稳定,易复发,而且乳汁中含有大量药物残留,直接危害人类健康。中药属于纯天然制品,含有多种生物有效成分,不易产生细菌耐药性,毒副作用小,无残留或低残留, 相似文献

奶牛乳房炎是严重影响奶牛业发展和危害人体健康的奶牛常见病。近几年来畜牧兽医工作者也加强了这方面的研究,研制了许多治疗奶牛乳房炎的方剂(如公英散、消乳痈散、和乳汤、乳痈验方、全蒲汤、乳疾宁等),以副作用较少的中草药制剂代替抗生素的治疗,其治疗效果是肯定的。但同时也发现所用的中药方剂的剂型也是不同的。那么同一方剂的不同剂型治疗效果又如何呢?为了进一步提高疗效,我们选择了几种方剂,制成不同剂型,在临床治疗奶牛乳房炎过程中进行了比较试验,现介绍如下。 相似文献

本研究利用BNT诊断法普查,应用乳炎康对5头患有“+”隐性乳房炎奶牛。15头患有“++”隐性乳房炎奶牛。5头患有“+++”隐性乳房炎奶牛进行治疗效果试验,结果表明:显效率均达100%。对奶牛“+”治愈100%,对“++”奶牛治愈率80%。比青霉素药物治疗对照组提高20个百分点:对“+++”奶牛治愈率60%。试验中对15头患有“++”隐性乳房炎奶牛进行乳炎康不同剂量的治疗效果试验结果发现.以开水冲后加清凉水调匀口服。每日一次,每次每头牛300克,连用5天,治疗效果最佳。临床推荐该量。临床观察治愈后试验牛无任何不良反应,所产牛奶各项指标全部达到国家标准,中药“乳炎康”对奶牛及所产牛奶无任何不良影响。经生物统计学方法计算,乳炎康对奶牛乳房炎治疗效果极显著(P〈0.01)。 相似文献

中、西兽药配合治疗奶牛临床型乳房炎的效果 总被引:15,自引:1,他引:15
奶牛患临床型乳房炎时,乳房和乳汁均有肉眼可见的异常,主要症状为红、肿、热、痛、乳汁清稀、有絮片、凝块,乳汁分泌减少等。根据8511农场资料统计,临床型乳房炎的患病率占成年乳牛的30%,个别的奶牛场高达60%。 我们经过多年的临床实践,采取中药散剂乳房消肿散和西药针剂特效米先,治疗临床型奶牛乳房炎,取得了令人满意的效果,现报告如下。1.材料与方法:1.1 病例来源 病牛分别来自8511农场6个奶牛场共计153头。1.2 病例选择 患病乳房出现红、肿、热、痛及乳汁出现絮状物,乳汁分泌不畅并明显减少。重… 相似文献

中草药对奶牛子宫内膜炎治疗的研究进展 总被引:1,自引:0,他引:1
在奶牛养殖业中,奶牛子宫内膜炎是一种较为常见的多发病,多集中在产后2周内,一般发病率为20%-35%。它通常是子宫膜的黏液性或脓性炎症,由于炎症所产生的有毒物质可致死精子和胚胎而成为奶牛不孕的常见原因之一,我国奶牛子宫内膜炎型不孕症占成年母牛不孕症的17%以上。目前绝大多数的养殖场还是大量的应用抗生素、激素类化学药品去预防和治疗该病的发生,虽具有一定的疗效,但这些药物使用后会在乳中残留产生“有抗奶”,而且滥用药物会致使动物产生耐药性和“三致”反应。所以,资源丰富、残留量少的中草药防治奶牛子宫内膜炎便成了人们关注的焦点。中草药属于天然药物,具有明显的抗菌消炎、改善血液循环和增强子宫收缩的效果,如经过科学的配制,将对奶牛子宫内膜炎的防治起到很大的作用。 相似文献

Subclinical mastitis with a raised somatic cell count was diagnosed in a cow in her fifth lactation. It was caused by Yersinia pseudotuberculosis, which can also infect humans. This is the first time that Yersinia pseudotuberculosis has been isolated from a mastitis sample in The Netherlands. Despite treatment with antibiotics in the dry period, Yersinia pseudotuberculosis was still present in the same quarter in the subsequent lactation. The somatic cell count was still high and milk production was much lower than in previous lactation. The pathogen did not spread to other quarters of the same cow or to herd mates on the farm over a 1-year period. 相似文献

A mixed-breed beef cow was presented with swelling of the front and hind left quarters of the mammary gland and mild depression. Direct examination and culture of the serosanguinous-like milk samples collected from these quarters were consistent with Bacillus anthracis infection. 相似文献

经确诊为临床型乳房炎的96只波尔羊作为研究对象,分为两组,每组48只,分别采用纯中药涂剂和青、链霉素治疗。试验结果显示:纯中药涂剂治疗临床型乳房炎波尔羊48例,治愈37例,治愈率77%,好转9例,无效2例,总有效率95.8%;用青、链霉素共治疗48例,治愈28例,治愈率58.3%,好转12例,无效8例,总有效率83.3%。经检验,纯中药涂剂对波尔羊临床乳房炎的治愈率、总有效率明显高于青、链霉素(P<0.05)。 相似文献

以85头患乳房炎奶牛共104个乳区为研究对象,随机分为4组,每组26个,分别用重组溶葡萄球菌酶粉低(200U/乳区)、中(400U/乳区)、高(800U/乳区)三个剂量,对照组为青霉素G钠(160万IU/乳区),每天早晚挤奶后乳池灌注给药,共4d,研究不同剂量重组溶葡萄球菌酶对奶牛乳房炎的治疗效果。试验结果显示,低、中、高剂量重组溶葡萄球菌酶均能有效清除感染乳区的链球菌、葡萄球菌、化脓隐秘杆菌等G^+菌,大幅降低牛奶中的白细胞数,提高日产奶量。其中低剂量组对隐性乳房炎、临床型乳房炎的有效率和治愈率略优于青霉素G钠(P〉0.05);中、高剂量对隐性乳房炎、临床型乳房炎的有效率和治愈率显著优于青霉素G钠(P〈0.05);中、高剂量的疗效相当(P〉0.05)。重组溶葡萄球菌酶是一种很好的治疗奶牛隐性乳房炎和临床乳房炎备选药物。 相似文献

Sales of intramammary cerates to a group of 142 dairy farms over a period of two years were monitored. On the assumption that three tubes of cerate are used to treat one case of mastitis, an estimate was made of the prevalence of clinical mastitis in these herds. The prevalence in seasonal supply herds was 21 cases per 100 cows per year and the prevalence in town supply herds was 66 cases per 100 cows per year. The usage of dry cow therapy was related to changes in the prevalence of clinical mastitis in these herds. The use of whole-herd therapy reduced the prevalence of clinical mastitis in herds which had a high prevalence in the first year, but in herds with a low prevalence of clinical mastitis the prevalence increased after the use of dry cow therapy. 相似文献

AIM: To compare the bacteriological and clinical cure rates for clinical and subclinical mastitis in New Zealand dairy cows following treatment with either an intramammary penicillin-dihydrosptreptomycin preparation or a subcutaneous injection of penethamate hydriodide. METHODS: Milk samples were collected from clinical and subclinical cases of mastitis before and 14 and 21 days after initiation of treatment for bacteriological culture, somatic cell count determination and conductivity testing. RESULTS: No significant differences in the bacteriological cure rate of major Gram-positive pathogens, clinical cure rate, somatic cell count or conductivity were found between treatments. However, the bacteriological cure rate of coagulase-negative staphylococcus infections and the overall bacteriological cure rate was lower for quarters treated with penethamate than with penicillin-dihydrosptreptomycin. CONCLUSIONS: The bacteriological cure rate of mastitis caused by major Gram-positive pathogens, the clinical cure rate, somatic cell count and conductivity did not differ between the two antibiotic treatments. . 相似文献
