入栏猪合理分群与管理

1.猪的生理特性.猪的嗅觉比较发达,仔猪出生几小时后就能辨别不同的气味,能辨别群体内的不同个体.猪的听觉分析器很完善,并能辨别声音的强度、音调和节律.猪的视觉很弱,不靠近物体就看不见.但猪群的群体位次明显,当一个猪群形成较稳定的群体中加入新的猪只时,就引起骚乱或争斗,经几天新的位次建立后才能逐渐安定下来.     

打造有机脐橙产业促进奉节现代农业发展

"四川省安岳市的一个有机柠檬果实在美国市价达10美元","重庆市长寿湖的有机鱼售价达160元/kg","湖南沅江有机柑桔的收购价为普通柑桔的4倍"……都是普通的农产品,如此高的市价还供不应求,你也许不会相信,但这就是目前国内外有机食品的热销现状。     

学习贯彻《农产品质量安全法》，确保蜂产品质量安全

<中华人民共和国农产品质量安全法>的颁布施行,与我们的生活息息相关,因为我们每一个人都是农产品的消费者,更重要的是该法所调整的是农产品的生产、销售人,作为养蜂者更不能置身事外.下面,笔者从基层养蜂工作管理者的视角,根据该法的有关条款探讨与养蜂的关系以及当前养蜂与该法要求还存在的差距和如何配合该法的实施,确保蜂产品质量安全,谈一些看法.

母猪矿物质储备的损耗——如何满足高产母猪对矿物质的营养需要

高产母猪对矿物质的需要尚不是很明确.迄今为止的研究证实,随着胎次的增加,母猪体内的常量元素和微量元素储备逐渐减少,而且高繁殖力还加剧矿物质的丢失.母猪的繁殖周期中有些时期(通常是妊娠后期和哺乳阶段)对常量元素和微量元素的需要量很高,但这些元素在其它时期也同样非常重要.然而简单地增加母猪饲粮中的常量元素和微量元素的含量可能并不是理想的方法,因为这种方法可能降低母猪的繁殖性能.近期的研究表明,有机微量元素能提高母猪6胎以上的窝产仔数.已有研究表明,虽然有机硒具有提高母猪繁殖性能的功效,但其它微量元素可能也在提高母猪繁殖性能方面发挥了相应的作用.     

江苏泰州市宠物犬寄生虫感染情况调查

犬的寄生虫病是危害犬健康的一大类疾病.犬感染寄生虫种类多种多样,不仅使其生长发育受到影响,而且还会使其对其他疾病的抵抗力减弱,从而感染某些疾病,严重者甚至导致犬的死亡.而有些寄生虫病是人兽共患的,所以,与人亲密接触的宠物犬的寄生虫病直接影响着人的身体健康.     

异地购买长途调运仔猪技术

沭阳县仔猪交易市场是华东地区最大的仔猪交易市场,每天有5 000余头仔猪被调往全国各地,路途远的有黑龙江、四川、福建等地的客商到沐阳来调运仔猪,如此长距离的运输给仔猪造成了很大应激,再加上许多客商没有长途调运仔猪的经验和技术,导致购回的仔猪有部分生病、有的甚至死亡,给一些外地养猪户造成较大的经济损失.     

隔夜茶新说

茶是非常健康的饮品，茶叶中含有丰富的营养物质和药效保健成分，具有生津止渴、帮助消化、杀菌消炎、降血压、抗癌、抗衰老等功效，是一种具有营养价值和保健功能的优良饮料。而隔夜茶一般是指茶叶浸泡超过12个小时以上，或者搁置了一晚上的茶。但人们常说：“隔夜茶，毒如蛇”，因此很多人在喝茶的时候，都会选择喝刚泡好的新茶，而把前一天泡的茶水倒掉，造成了很大的浪费。通过综合论述隔夜茶会不会致癌、隔夜茶是否卫生及隔夜茶的功效等相关内容，以期给读者正确的认识。     

肉鸡好销几法

温度控制是改善雏鸡健康状况的重要因素

鸡是一种恒温动物．即在一定的范围内,它们能够像哺乳动物那样调节自身体温。鸡胚和新生雏鸡对环境条件的变化特别是对温度的变化非常敏感。低温（包括因气雾免疫接种造成的低温）可能对鸡群的采食量和免疫系统的刺激产生灾难性的影响。     

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.
