秋蚕的饲养技术要点

目前秋蚕分为中秋蚕和晚秋蚕。8月中旬收蚁的蚕为中秋蚕，9月上旬收蚁的蚕为晚秋蚕。秋蚕的饲养好坏，主要决定于叶质、气候条件和桑蚕病虫害，其次是蚕品种、技术设备条件等，因此，养好秋蚕，必须根据当地的气候、叶质和桑蚕病虫害等的发生特点，抓住关键，掌握时机，创造条件，努力做好各项技术处理，夺取秋蚕稳产高产。

小蚕共育与蚕业科技进步

1　小蚕共育的内涵、历史与组织形式 　　1.1　小蚕共育的内涵 　　小蚕共育是根据小蚕的生理特点，将一定数量的小蚕进行集中饲养和管理，以保证小蚕健康成长，为大蚕饲育打好基础的一种养蚕措施，是蚕桑生产高产、稳产、优质、高效的经济饲育形式。 　　1.2　小蚕共育源远流长 　　小蚕共育作为一种饲养形式，具有悠久的历史。日本约在1930年前后提出对小蚕共育实行补助奖励政策，到1960年前后，实行小蚕共育的占养蚕户数的43.9%，到1980年，共有小蚕共育所2514个，占养蚕户数的91.8%，日本由于普及了小蚕共育，从20世纪70年代以来，软化病、脓病等受害蚕茧的比例显著下降，使蚕病发生率控制在2%以下，保证了蚕茧生产的稳产高产。 　　我国在20世纪20～30年代，有关蚕业学校和机关，曾在农村创办了小蚕共育组织，并派出技术人员进行指导。有关消毒药品、加温燃料、桑叶、人工费用、蚕室蚕具租费等，均按参加共育的蚕种张数进行分摊。由于实行小蚕共育小蚕发育强健，饲养成绩好，费用又比独自饲养低，因此，自愿参加者日众。20世纪50年代起，中国小蚕共育得到更大发展，共育规模比过去大，共育组织几乎遍及各蚕区。 　　1.3　小蚕共育的组织形式     

玉林市夏秋蚕饲养主要技术措施

玉林地区夏秋蚕饲养量在逐年增多，但夏秋蚕期气候条件恶劣、叶质较春季差、夏秋蚕易暴发蚕病，因此，要养好夏秋蚕必须根据夏秋蚕的饲养特点，抓住关键点，掌握恶劣环境条件对蚕体生长发育影响的规律性，把握时机，创造条件，认真细致地处理好各个技术环节，才能夺取夏秋蚕的稳产和高产。     

浅议夏秋蚕饲养技术

说起饲养夏秋蚕，广大蚕农会自然想到，夏秋蚕不好养，蚕病多，蚕茧产量低。夏秋蚕为什么不好养?其原因是：夏秋蚕气候条件恶劣，病虫危害严重，桑叶质量差，养蚕环境留存病原多，易爆发蚕病。造成夏秋蚕单产低，蚕茧质量差，蚕农的经济效益不高。     

推广小蚕共育技术 提高养蚕经济效益

小蚕共育是根据小蚕的生理特点和生活习性，将一定数量的小蚕进行统一集中饲养和管理，以保证小蚕发育整齐、体质强健，为大蚕饲养打好基础的一种科学饲养模式。通过组织小蚕共育，充分发挥养蚕能手的作用，提高小蚕饲养水平，降低小蚕饲养成本，提高张产、茧质和经济效益。

搞好小蚕共育的技术措施

蚕种的集体催青和小蚕共育，已成为蚕桑生产中的重要技术措施，实行小蚕共育不仅能节省蚕室、蚕具及升温等设备，减少蚕用物资消耗，解决蚕农养小蚕难的问题，同时有利于培养技术力量，有利于统一技术要求，加强技术处理，贯彻科学养蚕技术措施，使蚕儿体质强健，为养好大蚕打下良好基础。小蚕共育质量的好坏，直接关系到蚕茧产量和质量，关系到蚕农养蚕收入的提高，关系到蚕桑生产的持续发展。因此，搞好小蚕共育应抓好有关技术环节。ｌ 狠抓蚕前消毒，确保蚕作安全 共育室及蚕具应在充分打扫、清洗、暴晒的基础上，进行化学药剂消毒。第一…     

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.
