在整个全球人类消费持续增长的大前提下,预测今后的10年、20年甚至30年里,对粮食的需求尤其是肉、蛋、奶的需求将会持续的增长。这种增长在不同的国家表现也不同, 相似文献

2005年,在玉米丰产、消费变化、出口活跃、政策指引等一系列市场因素的影响下,农民、粮食经营企业、贸易商以及生产加工企业在这一年感受到了市场的“严冬”和“盛夏”。不同阶段不同的多空因素发挥着各自的能量,市场价格也在此中不断变幻。饲料及深加工需求仍迅速增长,国内饲料业虽然经历了猪链球菌及禽流感的洗礼,饲料产量需求仍保持相对平稳的增长态势,对玉米的需求也呈平稳增长态势。整体而言,2005年的玉米市场化进程加快。购销企业采购更为理性,全年市场呈平稳中阶段性上涨态势。 相似文献

据新华社信息专家预计,2005年我国大豆需求将从高速增长向平稳增长过渡,因此近期市场价格也将相对平稳。专家分析,在经过一段时期的高速增长后,国内市场对于大豆及制品的需求增长将可能放缓。1999年以来,国内大豆供求数量增长了40%,而同期国内畜牧业发展速度仅为5%左右,豆粕需求的增加必然受到畜牧业发展的制约。2003年以来豆粕需求不旺,供过于求矛盾突出也反映了这一点。因此2005年国内市场大豆需求将保持平稳发展。另一方面,在经过一轮高速扩张后,国内大豆压榨产业扩张步伐减缓,企业库存需求趋于稳定。而且2004年以来大豆价格波动给部分盲… 相似文献

2011年,高企的石油和商品价格,中东地区的动荡不安,日本的地震和海啸以及欧元区债务危机,美国国债上限的争论不休导致的信用可能的下调等系列事件使世界经济增长下滑,经济复苏的步履更加艰难。另一方面,自2008年来,国际乳业总体形势一直较好,奶牛存栏及单产、牛奶总产量、奶价及盈利都有不同程度的提高,乳制品的出口和消费在增长,新兴国家的进口达到创纪录水平。尽管2011年世界严峻的经济形势会影响全球乳业继续增长的幅度,但增长会继续。2012年,全球乳及乳制品的产量和出口会继续增长,中国、印度、俄罗斯这样的新型经济体的巨大需求还会延续,甚至会继续增长,成为拉动世界乳业和市场增长的最强大的动力。 相似文献

世界肉类市场在20世纪末显示出肉类供应过剩的特点 ,这是由于亚洲对肉类需求增长趋势中断 ,俄罗斯消费下降 ,而大洋洲和美国谷物丰收和畜牧业的发展 ,肉类数量多而需求下降 ,造成肉类供应过剩 ,至少是牛肉供应过剩 ,这种状况并将持续数年 ,对全球肉类市场构成了一定压力。预计全世界肉类产量在今后几年每年将增长1.9 % ,其中猪肉将增长53.6% ,禽肉将增长38.7 % ,牛肉将增长7.6 %。预计2000年。全球肉类需求的增长将会较为缓慢。有预测说 ,印尼、俄罗斯、乌克兰等国内在今后5年内肉类消费每年将减少1.2 % ,而中国则… 相似文献

2020年中国乳制品消费需求实现十五年来最快增长。在需求增长和成本上升双重驱动下,下半年生鲜奶价格持续升高,全年均价同比增长3.8%。奶牛养殖盈利状况得到明显改善,年均毛利润率达到13.4%。全年乳制品进口总量328.1万t,同比增长10.4%。乳制品净进口折合原料奶1887.2万t,奶源自给率为65.3%,连续5年下降,但是降幅连续4年收窄。综合判断,2021年生鲜奶价格回调压力增大,乳制品消费需求增速可能放缓,乳制品进口总量仍将小幅增长。为加快奶业升级发展,应着力加强市场稳定和风险防控机制建设,继续加强产业链利益联结机制建设,在规范化、标准化的基础上继续促进家庭牧场发展,在质量安全的基础上稳步推进奶农办加工及其他奶业新业态、新模式,加快推进农业供给侧结构性改革和促进优质饲料饲草种植。 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
