仔猪饲养管理要点

在生猪养殖过程中影响养殖效益的因素很多,其中仔猪阶段养殖好坏直接关系到整个周期的养殖效益。因此要加强仔猪的饲养管理,从哺乳仔猪和断奶仔猪阶段入手,减少仔猪初生和断奶应激,充分发挥仔猪生长潜力,加快仔猪增重速度,降低仔猪死亡率,提高养猪效益。     

浅谈哺乳仔猪的管理要点

哺乳仔猪是从出生到断奶前的仔猪,是生猪养殖的关键阶段,其生长速度和饲料转化率直接影响到养殖场户的效益,因此要根据哺乳仔猪的生理特点进行合理、科学地管理,提高养殖效益.     

哺乳仔猪死亡原因及综合防控策略

<正>规模化猪场管理好哺乳期母猪和仔猪,对优化整群、降低本场发病、增加综合养殖效益有着重大意义。结合生猪养殖实践总结,养殖者要全面掌握哺乳仔猪的生理特点和养殖过程中各种致死原因,针对性采取科学防控策略,坚持"以防为主、防治结合",才能达到哺乳仔猪"防病、增重、增收"几方面的协调统一,保障自繁自养猪场降低疫病死亡风险,从而获得更高养殖效益。1哺乳仔猪的生理特点概述(1)其营养供应主要来源于母乳。1~3日龄新生仔猪吃     

强制补料地哺乳仔猪日增重的影响

哺乳仔猪９窝,随机分成３组,１组为人工强制补料,Ⅱ组为训练强制补料,Ⅲ组为诱食补料,试验表明,在哺乳期间,各组间日增重差异不显著。     

哺乳仔猪的生理特点及饲养管理

哺乳仔猪是养猪业的生产基础。养育哺乳仔猪的任务是获得最高的成活率和最大断乳窝重和个体重。在生产实践中只要根据哺乳仔猪生长发育规律和生理特点,采取相应的饲养管理措施,即可达到成活率高,增重快的目的。     

影响哺乳仔猪成活率的因素分析

在生猪的养殖管理过程中,仔猪的成活率直接影响了养殖场的经济效益。仔猪的哺乳阶段是死亡率较高的阶段,特别是在农村,由于养殖户缺少技术和管理不到位,哺乳仔猪的成活率较低。本文主要阐述了影响哺乳仔猪成活率的因素,并提出了提高哺乳仔猪成活率的措施。     

哺乳仔猪的生理特点与饲养管理技术

生猪养殖时,哺乳仔猪饲养管理是否合理,是影响其成活率的重要因素.因此为保哺乳仔猪成活率,提高养殖效益,科学规范管理哺乳仔猪至关重要.基于此,本文首先分析了哺乳仔猪的生理特点;其次重点探讨了哺乳仔猪饲养管理技术要点.     

提高哺乳仔猪成活率的主要措施

哺乳仔猪是生猪养殖场的基础,是发展规模及扩大数量再生产,提高养殖质量和降低生产成本的关键之一。本文探讨提高哺乳仔猪成活率的若干措施,以期给生猪养殖户提供帮助。     

注射初乳对提高哺乳仔猪的增重效果

哺乳仔猪（７ 日龄） 采取注射初乳的试验组,与未注射初乳的对照组,试验全期（５３ 天） 两组哺乳仔猪的日均增重分别为２２５ ±２２ｇ 和１９５ ±２７ｇ ,差异极显著（ Ｐ＜ ０ ．０１） 。试验组试验全期比对照组提高经济效益１５４ ％ ,同时还能大大降低哺乳仔猪的发病率。     

浅谈动物福利与哺乳仔猪健康养殖

近年,生猪规模化养殖生产中最突出的问题就是哺乳仔猪营养与用药均存在诸多安全隐患,比如农村农民普遍形成了哺乳仔猪期至育成期大量使用市购颗粒饲料、浓缩精料及饲料添加物的习惯,这样不但严重伤害仔猪免疫器官,影响猪肉品质和猪只增重,还危害生态环境和人类健康。因此,"动物福利"这一全新的理念体系逐步形成,国内国际不少先驱者探索将动物福利贯穿于动物养殖全程,取得了进展性成效。笔者结合自场养殖生产实践,将动物福利理念应用于哺乳仔猪养殖过程,切实解决了哺乳仔猪生产中客观存在的一些制约问题,进一步加深从业人员对动物福利的认识,验证了动物福利应用技术的正确性和科学性。     

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.
