2016年2月,受春节节日效应的影响,春节过后随着畜产品需求减弱,其价格缓慢回落。耗粮型畜产品中猪肉和鸡肉价格上涨幅度较大。受天气影响和牛肉进口数量的增加,牛肉价格呈小幅度下降;羊肉价格则小幅度上涨。受春节影响,饲料市场“高库存,低消耗”局面凸显,大部分饲料价格仍维持弱势;由于大豆进口量较2015年同期低,大豆价格小幅上涨。与2015年同期相比,猪肉、牛肉和大豆价格分别上涨36.10%、1.46%和12.52%,羊肉、鸡肉、鸡蛋、玉米、豆粕和棉粕价格分别下降9.85%、1.15%、6.40%、13.76%、18.21%和15.48%。 相似文献

文章基于2002年1月至2022年7月我国主要畜产品月度价格数据,利用UVSVM模型分别考察猪肉、牛肉、羊肉3种畜产品价格随机波动与价格之间的动态反馈关系。结果表明,猪肉价格的随机波动对猪肉价格影响较大,猪肉价格水平变化会对短期猪肉价格的随机波动产生正向影响。牛肉和羊肉价格的随机波动对各自价格的影响较小,牛肉和羊肉价格水平的变化会对短期价格的随机波动造成负向影响。文章提出了完善猪肉储备的调节机制,实现猪肉市场保供稳价,多措并举稳定牛羊肉供给,促进牛羊肉价格平稳运行的政策建议,以期保障畜产品供给、促进农业农村经济高质量发展。 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
