<正>导致羔羊食毛症的原因尚不明确。一般认为,羔羊生长期营养供给不足,尤其是钙磷比例失调,导致矿物质代谢障碍,诱发羔羊啃咬被污染的皮毛。食毛症常见于舍养羔羊,由于羔羊营养补给不均衡,导致食入大量的羊毛引起消化系统紊乱和皱胃阻塞而形成的一种代谢病。此病于冬羔、春羔均有发生,尤其是冬季最为常见。羔羊舔食羊毛,羊毛进入皱胃形成毛球滞留其中,时间久了,随着滞留量增多,除了影响羔羊消化之外,还可导致肠梗死,严重的可造成羔羊死亡,为羊群养殖带来极大的 相似文献

羔羊因某些营养物质缺乏而舔食羊毛,在胃肠中形成毛球,引起消化紊乱和胃肠道阻塞幽门的一种代谢病。本病多发于秋末冬初,以细毛羔羊最为常见,常造成羊毛损失和羔羊死亡,给畜牧业生产造成了一定的经济损失。1病例我县八里镇郭某家有母羊25只、羔羊39只,于2017?年10月中旬开始,有的母羊被毛被羔羊常常舔食,有的羔羊有啃木槽、墙皮。11月初有15只羔羊食欲出现时好时坏,相继又有8只羔羊和3只7月龄的羊,食欲时好时坏,有时出现瘤胃轻度臌气。畜主认为羊患前胃弛缓和消化不良灌服一些健胃散,食欲有些好转。不久又出现不吃,日益消瘦,不排粪或粪干,口流涎,可视黏膜苍白,又认为是瘤胃积食,灌服石蜡油200ml。治疗次日有3只羔羊卧地不起,不久死亡。随即前来求诊。 相似文献

羊食毛症主要发生于冬春时节舍饲的羔羊。由于舍饲的羔羊食毛过多,除影响羔羊消化外,严重时因食入毛球阻塞肠道形成肠梗塞而造成死亡。近年来,由于限地放牧,常发生地方性成年羊食毛症。其临床特征为,羔羊发生毛球阻塞幽门和肠道,表现不排粪、腹痛、腹胀、脱水。成年羊常在一群中互相啃食被毛,大群羊被毛脱落,出现裸体羊。1发病原因1.1母羊及羔羊日粮中的矿物质和维生素含量不足,特别是钙、磷的缺乏或比例失调,可导致矿物质代谢障碍。1.2哺乳期中的羔毛生长速度特别快,需要大量生长羊毛所必需的含硫丰富的蛋白质或氨基酸。如果这时此类蛋白质… 相似文献

羔羊食毛症主要发生于舍饲的羔羊。由于舍饲的羔羊食毛量过多，除影响羔羊消化外，严重时可因食入毛球阻塞肠道形成肠梗阻而死亡。１发病原因一是母羊及羔羊日粮中的矿物质和维生素含量不足，特别是钙、磷的缺乏或比例失调，可导致矿物质代谢障碍。二是哺乳期中的羔羊毛生长速度特别快，需要大量生长羊毛所必需的含硫丰富的蛋白质或氨基酸如果这时此类蛋白质供应不足，会引起羔羊食毛。三是羔羊离乳后，放牧时间短，补饲不及时，羔羊饥饿时采食了混有羊毛的饲料和饲草而发病。四是分娩母羊的乳房周围、乳头、腿部的污毛没有剪掉，新生羔羊在… 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
