夏季谨防饲料霉变及霉菌毒素对猪的危害

在高温高湿、天气闷热的夏季里,猪场如果不加强饲养管理和注意饲料防霉等工作,极易导致猪群出现腹泻、饲料霉菌毒素中毒、母猪生产繁殖障碍或"高热病"等被动局面,将会严重影响养猪生产。因此,"防暑降温和防饲料霉变"是夏季养猪的关键措施。在饲料没有霉变或轻微霉变时,使用有效的防霉剂及采取其它防霉措施;在饲料霉变严重时,应及时更换饲料或科学、合理的选择使用绿色、安全、强力高效的复合脱霉剂,以减轻对猪的影响和危害。

春季畜禽饲料的防霉与去霉

现正直春季,春雨绵绵,气候变化无常,导致养殖户堆积的饲料出现霉变。据有关资料显示,全国每年因霉变饲料损失的粮食和饲料占总量的10%左右,平均每年死于霉饲料中毒的畜禽达上千万。饲料被霉菌污染后其营养价值也下降,因此可见,霉变饲料对畜禽养殖业带来的损失是巨大的,更加值得去思考防霉去霉的技术。1防霉技术

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.
