提高樱桃谷鸭父母代种鸭育成均匀度的技术措施 总被引:1,自引:0,他引:1
0年代以来,我国肉鸭养殖业发展十分迅速,规模养殖越来越大,由此刺激了许多鸭场和农户开始饲养父母代肉用种鸭。一些鸭场和农户在饲养父母代肉用种鸭过程中,忽视了种鸭在培育过程中严格控制标准体重和保持鸭群群体的均匀度,致使部分种鸭过肥或体重不足,影响了鸭群的... 相似文献

北京鸭在铁岭地区的饲养观察 总被引:2,自引:0,他引:2
北京鸭原产于北京西郊玉泉山一带,是世界著名的肉用鸭品种。2000年辽宁省铁岭地区部分农户采用网上饲养方式,应用全进全出饲养制度,饲养北京鸭15000只收到了良好的饲养效果,获得了较大的经济效益。现将北京鸭的饲养效果观察报告如下:1 饲养情况1.1 育雏前准备做好育雏舍及设备的清洁卫生和消毒工作。打扫冲洗完毕用高锰酸钾和福尔马林熏蒸24小时,开窗透气。进雏前1~2天将育雏室预温,使其温度达到24℃,备好饲养雏鸭的饲料、药品等物资。1.2 饲养技术饮水与开食:雏鸭出壳后24~36小时用手敲打饮水器的边缘,引导雏鸭饮水。对个… 相似文献

金定鸭是我国优秀的蛋用鸭品种之一.原产于福建省,以产蛋多、蛋大、绿壳蛋比例高、蛋黄比例高和蛋品质好而著称于世.目前在我国很多地区都有较大规模的饲养。黑龙江省近年来大力发展养鸭业,金定鸭也有一定的饲养量.但因我省地处寒冷地区,缺乏一套适合寒冷地区的饲养管理技术.致使金定鸭生产性能得不到很好的发挥,从而影响了养鸭生产的经济效益。笔者就这一问题,结合多年饲养金定鸭的生产实践经验,总结如下.以供广大从业人员参考。[编者按] 相似文献

谈谈鸭传染性浆膜炎和大肠杆菌病的防治 总被引:1,自引:0,他引:1
在我国饲养的水禽中,鸭的数量占绝大多数。一般以农户小规模饲养为主,饲养的环境和兽医卫生相对都比较差,尤其是旱地饲养条件更差,因此容易感染鸭传染性浆膜炎和大肠杆菌病这2种疫病,同时也造成环境的污染。传染性浆膜炎和大肠杆菌病在一些地区经常发生混合或继发感染,当防治不当时,饲养到2—4周龄开始发病,而且批批发生。2种疫病混合或继发感染,其发病率和死亡率较高,有的农户连续几批亏本后就不敢再饲养了。这样必将阻碍养鸭业的发展。现将有关 相似文献

1本地区樱桃谷种鸭饲养概况
最近两年里,在徐州地区有很多农民参加樱桃谷父母代SM3种鸭的养殖,采用“公司+农户”的养殖模式,由一些主营樱桃谷种鸭的企业提供父母代种鸭苗,同时负责饲料供应、疫病防治、种蛋回收和技术指导等,农户自建鸭舍并承担种鸭的日常饲养和管理工作。经过几年的实践证明,这一互利共赢的模式切实可行,它大大降低了养殖风险,有利于农民的创业致富,带动了农村经济发展,在本地区很受农民和政府的欢迎。 相似文献

水禽房舍旱养技术 总被引:1,自引:0,他引:1
劳创波 《养殖与饲料.饲料世界》2008,(12):10-12
番鸭也称作“旱鸭”,意即不用水面也能正常饲养的鸭子,并且饲养效果和有水面的相差不大。除了番鸭以外,樱桃谷鸭、北京鸭、天府肉鸭、上海白鸭等一些肉鸭品种,也被旱养成功,只是效果比有水面的差一些,且饲养要有较大的运动场。其它一些品种,像本地麻鸭、各种蛋鸭等,历来没有水面则很难饲养。 相似文献

我区放牧蛋鸭和蛋品加工历史悠久.由于农业生产方式、耕作制度的不断发展,蛋鸭放牧饲养逐渐改为圈养.新的生产方式必须与新的生产技术配套,生产才能正常进行.现根据我区实际,就如何提高蛋鸭生产经济效益的技术措施进行初步探讨.1品种选择不同的品种要求不同的饲养条件.有的品种如金定鸭、康贝尔鸭等,个体较大,步行速度慢,觅食能力较差,采用圈养方式,供应足够的配合料,可以发挥体大、蛋大的优势;而洞庭麻鸭,攸县鸭等品种则适于放政方式.1996年冬我们对几个品种在圈养条件下的生产性能作了调查,这些农户都是采用我区同一饲… 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
