瘤胃酸中毒系瘤胃积食的一种特殊类型,又称急性碳水化合物过食、谷物过食、乳酸酸中毒、消化性酸中毒、酸性消化不良以及过食豆谷综合征等。是因过食了富含碳水化合物的谷物饲料,于瘤胃内发酵产生大量乳酸后引起的急性乳酸中毒病,在临床上以精神沉郁、瘤胃臌胀、脱水等为特征。 相似文献

正瘤胃酸中毒系瘤胃积食的一种特殊类型,又称急性碳水化合物过食、谷物过食、乳酸酸中毒、酸性消化不良、消化性酸中毒、中毒性消化不良,以及过食豆谷综合征等。许多农民及养殖户"过食精料",但过食豆谷物精料和过食豆类精料所引起的疾病是根本不同的,过食豆类精料引发的是瘤胃碱中毒而不是酸中毒。近年的研究表明,反刍动物过食谷物的发病是乳酸与来源于瘤胃内的细菌内毒素等有害物质共同作用的结果。因 相似文献

羊瘤胃酸中毒又称食豆谷综合征、酸性消化不良、乳酸中毒等,是由于突然采食谷粒等富含可溶性糖类物质,瘤胃内急剧产生、积聚并吸收大量乳酸等有毒物质所致的一种急性消化性酸中毒。此病的发生常见于因贪食或偷食过量的精料所致,对养羊业具有危害性。现将黑龙江省大庆某种羊场澳洲道塞特原种肉羊瘤胃酸中毒的发病情况、临床表现、尸体剖检、诊断和防治情况介绍如下。1发病情况2005年5月12日,黑龙江省大庆种羊场送来1只刚刚死亡的澳洲道塞特原种肉羊,该种羊场有种羊240多只,有14只种羊发病,发病率约为7%。2临床表现发病初期该羊精神沉郁,食欲… 相似文献

反刍动物采食了大量难以消化的粗硬饲料或容易膨胀发酵的精料所引起的疾病,以往均属于瘤胃积食的范畴。但从40年代开始,国外学者发现反刍动物过食谷物饲料(高碳水化合物饲料)后,可以导致瘤胃酸中毒。其后国内外许多学者先后对本病进行了研究,特别是70年代后,各国学者对该病的病因、发病机理和临床表现进行了更深入地探 相似文献

<正>瘤胃酸中毒是反刍动物采食了过量易发酵的碳水化合物饲料,在瘤胃内产生大量乳酸而引起的以前胃机能障碍为主的一种疾病。本病主要发生于乳牛和奶山羊,役用牛和绵羊、鹿偶有发生。瘤胃酸中毒又称乳酸中毒、过食症或豆谷过食症。1发病原因由于突然采食或偷食了大量的富含碳水化合物的饲料,特别是谷物,如小麦、玉米、大麦、高粱和谷子等,被反刍动物采食后,在瘤胃微生物的作用下,极易引起本病。长期过量食用块根 相似文献

牛瘤胃酸中毒的诊断与救治 总被引：2，自引：0，他引：2
牛瘤胃酸中毒多由于突然超量喂食玉米、麦子、高粱等富含可溶性糖类饲料,使牛瘤胃内急剧产生和吸收大量乳酸等有毒物质,所引发一种急性消化性酸中毒,也叫乳酸血症.牛瘤胃酸中毒后,发病急,如得不到快速救治,则病程短,死得快.最急性型3～5h常突然死亡,急性型也多在1d内死亡. 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

近几年,世界饲用添加剂市场增长较快,预计今后将进一步增长,据世界粮农组织(FAO)首领会议的倡议,到2015年,将使世界营养不良的人口削减一半,其间,肉制品将会以每年2％的速度增长,特别是加快猪肉和禽肉增长。这将促进世界添加剂,尤其是蛋氨酸和赖氨酸需求量的增加。 相似文献
