母猪产后不食的分型疗法

(一)病因类型 1.消化不良型:母猪产前精料喂的过多,或突然更换饲料,加重胃肠负担,引起消化不良.此病常发于分娩之后,体温正常,食欲不振,粪便先干后稀,有的病猪喜欢喝点成汤,有的吃点鲜块茎和生米等食物,但数量不大,严重者食欲废绝.     

国内玉米价格涨跌两难

对河南桑蚕“十一·五”发展规划的几点建议

<正>河南省地处黄河中下游，蚕业生产历史悠久。建国50年以来，尤其是近20g间，经过“七·五”至“八·五”的迅速发展和“九·五”、“十·五”的稳步调整，河南蚕业生产规模基本稳定，生产水平得到提高。目前全省桑园面积1．67万hm~2，年产桑蚕茧6000t，与建国时相比，桑园面积和蚕茧产量分别增长了24倍和42．2倍，与改革开放初期的1978年相比，分别增长了2．25倍和4．18倍；蚕业深加工等综合产值达到10亿元，农民收入达5亿元，出口创汇8600多万美元。“九·五”、“十·五”期间，河南茧丝绸业保持着北方诸省(山东、陕西省除外)生产、出口主要基地和传统优势产业、出口创汇大户的地位。蚕业生产已成为不少平原和山区农民脱贫致富奔小康的支柱产业。 1 “九·五”、“十·五”实际生产情况 1．1 实际生产情况 1．1．1 生产规模保持基本稳定桑蚕生产在经历了1995年“全面下滑”桑园规模大幅度缩减后，“九·五”期间，全省蚕茧的总产和年产量也相应减少，但集中产     

缩小分组饲养的面积

在丹麦,人们已经提出一个分组饲养妊娠母猪的新观念,名叫"最佳猪栏",它把群饲设备与单独饲喂和铺有稻草、排水良好的地面结合在一起,见图1.对这种设计的研究显示,给妊娠母猪建成一个既有饲喂/休息的去处,又有一个铺垫良好的躺卧处的猪栏-所占面积总量与配备给群饲母猪的电子饲喂系统的场地所使用的面积相当.     

发现商机的14大法则

商机无论大小,从经济意义上讲一定是能由此产生利润的机会.商机表现为需求的产生与满足的方式上在时间、地点、成本、数量、对象上的不平衡状态.旧的商机消失后,新的商机又会出现.没有商机,就不会有"交易"活动.商机转化为财富,必定满足五个"合适":合适的产品或服务,合适的客户,合适的价格,合适的时间,合适的渠道.目前我们能认识的商机大致可归结为14种:     

夏秋季节怎样防治乌龟红甲病

夏秋季节龟活动较多,或运输中腹甲损伤,或池子粗糙引起磨损龟甲后而导致龟甲内局部红肿发炎,多数常见于腹甲内部有出血斑块,并向四周浸润扩散,严重时可波及整个龟甲,引起败血症而死亡.池中水质差、消毒少、水底氧气少时易产生大量单孢杆菌是引起此病的元凶.     

Disease and destiny-mystery and mastery

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.     

Foot and mouth disease and bluetongue: differences and similarities

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.
