鹅亚硝酸盐中毒

鹅亚硝酸盐中毒１发病情况某养鹅户养鹅１２６只，以放牧为主，其中中雏鹅（４０日龄左右）８５只，成年鹅４１只，１９９２年１０月２日，河边堆放一堆烂白菜叶（约有６０公斤）早晨放牧时被鹅吃掉约有一半多，食后约３小时发现有６１只（８０％）中雏鹅、１６只（３３％...     

养鹅业仍具发展潜力

在2005年，鹅产品市场持续保持供销两旺的局面下，鹅产品的消费量日益增长，雏鹅，肉鹅一直在高价位运行，平均养一只鹅就获利4～8元。据统计，全国鹅的饲养量仅为8亿只左右。人均0.6只左右，全世界鹅的饲养量为14亿只左右，人均0．23只左右。且发达国家劳动力资源紧缺，一般不养鹅；而世界广大温热地区，也不适应养鹅。我国劳动力资源丰富，养鹅属劳动力密集产业，我国蛋质饲料资源短缺，养鹅能充分利用我国副产品资源。     

春节前后鹅苗价格

因受肉鹅销售价格的影响，2008年以来，特别是10月份以后，全国的鹅苗价格一直处于下滑状态，目前四川白鹅商品肉鹅鹅苗产地价每只3元左右，江苏每只2．50左右，朗德鹅每只8元左右，预计春节前各地鹅苗价格将降至低谷，局部地区的鹅苗售价有可能达到每只不足2元，按照前些年的惯例，进入农历正月十五以后，鹅苗价格将开始回暖上浮，今年冬季前期气温较往年偏高，     

鹅遗传育种研究进展及养鹅业的发展前景

我国饲养鹅的历史非常悠久，据考证，大约有３１００多年的历史。我国是世界上养鹅量最多的国家，据统计，９０年代初鹅存栏数已超过１亿只，１９９５年出栏鹅近４亿只（陈育新等，１９９７）。我国具有丰富的鹅种资源，分布遍及全国。由于鹅具有耐粗饲、饲料报酬高、抗病...     

种鹅暴发鹅副粘病毒病的诊断与防治

２００１年１－２月，安徽省无为县泥汊镇安福村一些种鹅户饲养的种鹅发生以消化道和呼吸道为特征的传染病，造成一批种鹅死亡，经诊断为鹅的副粘病毒病。此病的发生给农户造成一定的经济损失，并严重威胁着养鹅业的健康发展，现将诊治情况报告如下。一发病情况安福村共有种鹅养殖户３２户，饲养种鹅４６５３只，是无为县种鹅生产基地，主要品种为四川白鹅。该村地处沿江，有五年以上养种鹅历史，今年以来，３２户基本户户种鹅发病，一个月以来，先后有１２０３只种鹅发病，死亡８０６只，发病率为２５．８％，死亡率为１７．３％。二发病症…     

重视鹅的育种 促进鹅业发展

中国是世界上养鹅最多的国家，９０年代初鹅存栏数已超过１亿只，１９９５年出栏鹅近４亿只。８０％的农业人口在农村分散居住状态下从事半放牧养鹅，更能发挥鹅利用野生饲料的特性。中国鹅按体重分大、中、小三个类型，其产区以原产地为主，皆为地方品种。繁殖率高是中国鹅的优良特性。其中，豁眼鹅和四川白鹅的年产蛋量分别为１００枚和６０～７０枚。早期生长速度和肥肝性能均低于引进的外国同类型品种。利用现有品种素材选育标准品种乃至商用配套系是提高中国鹅综合生产性能的最佳途径。     

江苏养鹅业发展迅速

近年来，江苏省鹅业生产发展迅猛，１９９８年，全省鹅饲养量为７ ０４３万只，占全国鹅饲养量的１３．１６％；１９９９年鹅饲养量超过７ ３００万只，鹅业经济总量达１３亿元，已成为全国鹅业的领头雁。现有养鹅场（户）已达２万多个，年出栏鹅１２００多万只，分别比 １９９７年增长３５％和２１％。目前江苏省年出栏鹅百万只以上的县有２１个，其中扬州的高邮、宝应、邗江，苏州的吴江，南京的江宁，镇江的句容等县市年出栏量均超过２００万只。特别是扬州市，养鹅业已成为畜牧业的特色产业，１９９８年饲养量已达１３００万只，占全省…     

鹅病防治

1小鹅瘟此病 以预防为主。种鹅产蛋前1个月左右连用2次小鹅瘟疫苗超前免疫。雏鹅可用抗鹅瘟血清紧急免疫，每只皮下注射0．5mL。治疗时，15日龄以下每只注射1mL；15日龄以上每只注射2mL，隔日再注射1次，也可用高蛋黄注射液紧急防治。     

种草养鹅好处多

1节省精饲料 　　以往农户养一只商品鹅从雏鹅到出售需耗用精料 10 kg，通过种草养鹅，仅需精饲料 6 kg。 2降低成本 　　种植一亩黑麦草仅需成本 300元，而一亩黑麦草产量可累计饲养 250只鹅，折合成本平均每只商品鹅仅 1.2元。每只商品鹅通过种草可降低饲养成本 5元。 3节省劳动力 　　农民过去养鹅要经常外出割草，或者赶鹅放牧，易伤害庄稼，同时鹅易患传染病。而种植黑麦草基本上解决了鹅的青料，节省了劳动工时，同时鹅不放牧饲养，不易生病。 4牧草营养价值高 　　黑麦草叶丛期粗蛋白质占干物质的 15.3％～ 18.6％，有各种必需氨基酸…     

四季养鹅月月谈

（一）8月份我国鹅业生产要点 1．鹅苗。就全年鹅苗生产的规律来讲，8月份是鹅苗生产的淡季，绝大多数品种的种鹅仍处于休产期，东北地区因气温比南方低，仍有少量鹅苗可供，但价格每只在12元左右，朗德鹅苗可供数量更是稀少，价格达到每只30元左右。     

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.
