干乳期补充钙、亚硒酸钠维生素E对预防奶牛产后疾病和提高繁殖率的研究 总被引：1，自引：0，他引：1
奶牛产后瘫痪、乳房炎及产后泛情不排卵等是影响奶牛正常生产和繁殖生产性能的重要因素。近年来，为了预防和降低成年奶牛产后瘫痪、乳房炎的发病率，进一步提高能繁母牛的繁殖率，我们于１９９９年３月－７月间，对奶牛专业村农户饲养的成年奶牛，采取了干乳期给奶牛补充钙、亚硒酸钠维生素E的措施，对预防奶牛产后瘫痪、乳房炎、胎衣不下等病及提高奶牛繁殖率均取得了明显效果，现将试验情况总结如下。１．药品：市售１０％葡萄糖酸钙、亚硒酸钠维生素E粉（每袋１００g，每g含亚硒酸钠０．４mg、维生素E１０IU）。２．试验动物及用药方… 相似文献

研究不同胎次、妊娠天数、围产时间、犊牛初生重及月份与奶牛产后疾病的相关性,为降低奶牛产后疾病发病率提供参考。本文调查了宁夏某场2 975头中国荷斯坦牛不同胎次、妊娠天数及月份等对奶牛产后疾病胎衣不下、乳房炎、子宫炎、蹄病及产后瘫痪的影响程度,并进行相关分析。研究结果表明,随着胎次的增加,奶牛胎衣不下、乳房炎、蹄病和产后瘫痪的发病率逐渐增加,但对子宫炎发病率的影响不明显,其中第6胎奶牛的产后发病率最高。5-7月份奶牛产后疾病的发病率最高。妊娠天数和奶牛进入围产圈时间的增加使得产后疾病的发病率降低。犊牛初生重的增加使得奶牛胎衣不下和产后瘫痪的发病率升高。患胎衣不下导致乳房炎和子宫炎发病率增加,患蹄病导致胎衣不下、乳房炎和子宫炎发病率增加,产后瘫痪导致胎衣不下、乳房炎发病率增加。不同胎次、妊娠天数、产犊月份、围产时间和犊牛初生重对奶牛产后胎衣不下、乳房炎、子宫炎、蹄病和产后瘫痪有一定的影响,且产后疾病间相互影响。 相似文献

奶牛分娩后,胎衣在12 h内不能自然完全脱落者称为胎衣不下.胎衣不下是奶牛产后常见疾病之一,发病率通常在10%～25%.有些报道高达50%以上.胎衣不下常导致初产母牛首次配种的受胎率明显降低;而在经产母牛,胎衣不下不仅对产后繁殖力和产奶量影响显著,还极易继发子宫感染等多种疾病,不少胎衣不下奶牛因此不育而被淘汰.所以,长期以来奶牛胎衣不下一直是一个严重影响奶牛业发展的难题. 相似文献

母畜分娩后胎衣在正常时限内不排出称为胎衣不下或胎衣滞留。奶牛分娩后，胎衣在12小时以内不能自然完全脱落者为胎衣不下。胎衣不下是奶牛产后期长见疾病之一。发病率通常在10％～25％，有些报道高达50％以上。单纯胎衣不下的初产母牛，常使其产后首次配种受胎率明显降低。在经产母牛中，胎衣不下不仅对产后繁殖力和产奶量影响较大，而且极易继发子宫感染等疾病， 相似文献

围产康预防奶牛酮病生产瘫痪和胎衣不下的临床试验 总被引：1，自引：0，他引：1
应用围产康在８９６头产后奶牛上进行了预防酮病、生产瘫痪和胎衣不下的临床试验。结果表明试验牛产后血酮降低，血糖升高，而对照牛血酮牛高，血糖降低；胎衣不下的发病率试验牛极显著地低于对照牛，防病指数为０．６３２８；生产瘫痪的发病率试验牛显著低于对照牛，防病指数为０．７０６６。 相似文献

奶牛产后血钙浓度低于正常值时，就会出现一定的临床症状。轻度缺钙易造成前胃弛缓、产后胎衣不下；重度缺钙导致奶牛生产瘫痪。临床上采用葡萄糖酸钙静注，治疗饲喂低钙磷日粮的奶牛发生的前胃弛缓、胎衣不下、生产瘫痪方面的疾病，具有良好的疗效。 相似文献

When early people made their appearance, zoonotic infectious diseases were already waiting, but epidemic diseases did not appear in human history until people began to live in large numbers under conditions of close contact, mainly during the last 10,000 years. Disease has decimated urban populations, conquered armies, and disrupted society. The focus here is on (1) the plague of Athens and the Black Death; (2) smallpox, influenza, and rabies; (3) avian influenza prion diseases, and foot & mouth disease; and (4) emerging and re-emerging diseases. All have veterinary public health associations. In Athens, Greece, in 430 BC, when the Spartans ravaged the countryside, hordes crowded into Athens so that orderly movements, space in which to live, and adequate supplies of food became impossible. Crowding of any population fosters disease transmission; chaos and disorder enhance it all the more. Out of northern Egypt came a terrible plague from across the Mediterranean Sea. The identity of the plague of Athens remains unsure, but the well-considered conclusion is Rift Valley Fever, a mosquito borne, viral zoonosis. The Black Death, also called the Plague, raged in Asia for centuries. In 1347, the Black Death was brought by a ship out of Asia to Sicily. The scenes of devastation were repeated throughout Europe, with 90% or more of the people dying in city after city. Influenza, too, has been a cause of periodic human epidemics, but the great pandemic of influenza occurred in the last months of World War I. In the years of highest occurrence, more than half the world's population became clinically infected. If veterinary public health had been born earlier, it could have led to elucidating the epidemiology of influenza and the plagues of Athens, Europe, and Asia. In turn, smallpox had also caused continual tragedy. In 1796, Edward Jenner began to harvest pustules of cowpox from children or infected cows and inject them into susceptible children. In 1980, the World Health Organization declared that smallpox had been eliminated from the world. Rabies, though, still strikes terror. A number of animal diseases, broadly termed emerging and re-emerging diseases, need surveillance because they have the potential to impact human health. From late in 2003 to 2007, the highly pathogenic H5N1 influenza virus in poultry infected at least 121 people and caused 62 deaths in four countries. The prion diseases, too, all have very high numbers in concentrated contacts. To control these diseases, veterinary public health is essential, with diagnosis, epidemiological surveillance, clinical manifestations, and prevention as primary measures. 相似文献

On 26th of july 2007 a new case of bluetongue was notified in the Netherlands and on 2nd of august 2007 foot-and-mouth disease was diagnosed in Surrey, England, which raised the threat of having both infections simultaniously in one area. Bluetongue and foot-and-mouth disease have a different pathogenesis, but symptoms may resemble each other at a later stage of infection. The pathogenesis and possible clinical symptoms of both infections are discussed and illustrated with pictures. 相似文献
