中药贯众散对仔兔的增重试验 总被引：2，自引：0，他引：2
贯众散添加剂，具有促进仔兔生长，增加体重和防病治病的功能，它不同于矿物的，化学的，抗生素等添加剂，具有天然中药多种功能效应。试验证明：可使断奶仔兔生长发育加快，增重明显；在４０天试验期中，较对照组增重提高５９％，饲料转换率也高于对照组１８－２４％。另可防治仔兔腹泻等疾病，减少发病发和死亡率。 相似文献

仔兔38日龄左右断奶后,由于机体发育尚未完善,消化功能较弱,加之贪食精料,易发生消化系统疾病,从而影响仔兔的体重增加,造成生长发育的停滞.为了减少消化系统疾病的发生和提高仔兔的增重效果,笔者在仔兔饲料中添加一定量的碳酸氢钠,观察其对仔兔的增重效果等. 相似文献

笔者根据近几年的生产实践,依据仔兔的生长发育和母兔的泌乳规律,以及母兔泌乳与仔兔增重的关系,提出对仔兔提早补饲的管理手段,以提高仔兔的成活率和断奶窝重,缩短育肥周期,加快商品生产. 相似文献

为了准确掌握母兔的泌乳状况和仔兔增重速度,从而为有效地改善泌乳母兔及仔兔的饲养提供可靠依据,我们于1989年4月20日至5月30日在定西县种兔场,进行了青紫蓝母兔泌乳量及其仔兔生长发育的测定。 相似文献

幼兔如果饲养管理不当 ,不仅降低成活率和生长发育 ,也关系到良种特性能否充分表现和巩固提高。因此 ,加强幼兔时期的饲养管理对兔群的发展 ,质量的提高有重要意义。为此 ,笔者把几年来在生产实践中摸索出的能有效降低幼兔死亡率、促进幼兔生长发育的几点措施作一总结。1 加强仔兔的饲养管理 ,增强仔兔体质1 1 抓好补料关 仔兔开眼后因生长发育很快 ,母乳满足不了仔兔需求 ,因此肉、皮用兔一般在 1 6日龄、毛用兔在 1 8日龄即开始补料。补饲能使仔兔的消化器官与机能得到锻炼 ,促进胃肠发育与机能的健全。饲料要求容易消化、营养丰富 ,… 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
