Comparison between BSE and FMD

OA show ('918 '); [comparison of BSE and FMD] BSE and FMD are catastrophic diseases of cattle, sheep, pigs and other domestic animals, which have the characteristics of rapid onset, wide spread, high mortality and serious disasters If not handled effectively, it will often bring devastating impact on animal husbandry in a country and even the world; at the same time, it will cause great harm to human health According to the pathogenesis, BSE is a fatal brain and nervous system disease It is a subacute spongiform disease of bovine brain tissue It is suspected that BSE is caused by pathogenic animal protein in animal bone meal feed, and it is a food chain infectious disease Experts believe that this kind of disease can not only infect cattle, but also cross infect people and other animals People and animals can be infected after eating the brain, spinal cord, meat, viscera and other tissues of sick cattle, which is a very frightening case that is difficult to deal with in medicine at present Foot-and-mouth disease (FMD) is an acute disease of cloven hoofed animals caused by foot-and-mouth disease virus (FMD) of small RNA virus material It is a hot and highly contact infectious disease, which can spread rapidly among cloven hoofed animals such as pigs, cattle, sheep, etc it is characterized by blisters and ulcers in the mouth, nose, hoof and breast skin Malignant FMD can cause sudden death due to heart paralysis of livestock, which can cause sudden death of livestock A large area of dead acute disease Although foot-and-mouth disease virus can be killed in high temperature conditions, the harm to human infection is not as serious as mad cow disease, but the disastrous consequences to animals are no different from mad cow disease When BSE cuts off the food chain of animals, it can effectively control its spread, and foot-and-mouth disease can spread in many ways, even through air Therefore, its harm to animal husbandry is better than mad cow disease In terms of disaster scope, BSE mainly occurs in EU countries, while foot-and-mouth disease almost affects all continents Since the first case of BSE was found in England in 1986, it has only spread in China After that, proper measures such as slaughtering the infected animals and destroying the suspicious animal bone meal feed have been taken to control the disease for a time Until January 2000, BSE in England again exploded mysteriously, and quickly spread to France, Germany, Italy, Switzerland and Norway The crisis almost spread throughout Europe There are few cases of BSE reported on continent, but other continents Foot-and-mouth disease has been spreading rapidly since the first case was found in the UK in February On March 16, according to Nick brown, British agriculture minister, 137 cases of foot-and-mouth disease have been confirmed in the UK However, according to China Science and technology network on March 21, by March 20, the number of foot-and-mouth disease in the UK had soared to 394 Hundreds of thousands of livestock and carcasses will be slaughtered and destroyed In addition to the UK, the European continent, South America Brazil and Argentina, Japan, South Korea and Mongolia in East Asia, India in Southeast Asia, as well as Australia, the Middle East, Russia and the former CIS countries have found more than 20 countries that have been reported The direct economic loss will be much more than that of BSE, and the indirect loss and the negative impact on animal husbandry can not be estimated From the perspective of disaster prevention measures, BSE is relatively simple, because it is mainly transmitted through the food chain As long as the infected animals are destroyed and the animal bone meal is eliminated as feed, in addition, strengthening the management of breeding and fecal treatment can achieve the goal of epidemic control The prevention measures of foot-and-mouth disease are relatively complex Because it is a contact infection, and even can be transmitted by wind and air, in addition to the application of measures to prevent mad cow disease, corresponding isolation measures should be taken, including not only the animals themselves, but also the means of transport, feeding equipment, personnel, water source and feed that have been exposed to the source of the disease The difficulty can be imagined From the perspective of the impact on the price of feed grain, although BSE and FMD can endanger animal husbandry, they are the same in terms of harmfulness; however, their impact on the price of feed industry and related grains and processed products is different So, what kind of influence does mad cow disease and foot-and-mouth disease have on the food for feed production? This requires a specific analysis of specific issues The cause of BSE is to add animal's bone meal to feed The best way to cure BSE is to eliminate animal's bone meal as feed additive However, the reduction of animal protein is not conducive to the growth and fattening of animals Therefore, it is necessary to replace BSE with plant protein Soybean meal is an ideal substitute, and it is also a by-product of soybean processing Therefore, the outbreak of BSE will stimulate a large amount of demand for soybean meal in the feed industry, resulting in the rise of soybean meal and soybean price Although the reduction of the total amount of livestock will also lead to the reduction of the total amount of feed demand, such as rice bran, wheat bran, etc., but the demand for specific feed materials is not balanced In contrast to BSE, the prevalence of FMD will cause a large number of slaughtering of infected livestock, while the total number of livestock will be greatly reduced, which will greatly reduce the direct demand for feed, and there will be periodic surplus of soybean meal, wheat bran and other feed materials, resulting in the decline of soybean meal, wheat bran and the related soybean and wheat prices For example, BSE is positive for soybean and soybean meal futures, while FMD is negative for soybean and soybean meal futures On January 1 this year, the European Union made a decision to impose a six-month embargo on the implementation of animal bone and meat meal, and to destroy the infected animals, the carcasses of animals ready to process feed and the animal feed in question in the area, resulting in a shortage of vegetable protein demand for a short time, and a sharp increase in the demand for soybean meal in the feed industry in the region At the same time of increasing direct demand for soybean meal, because European countries are concerned about the consumption of beef and other meat products, and the export of beef products, including frozen meat and canned meat, is also resisted by all countries in the world, which reduces the amount of livestock raised, so dialectically speaking, it also discounts the direct increase of soybean meal Foot-and-mouth disease (FMD) appeared shortly after the outbreak of BSE, which spread faster, involved more areas and suffered more disasters, so its impact on the feed market is deeper and further It can be predicted that foot-and-mouth disease will have a stronger impact on soybean and soybean meal prices than mad cow disease, and the effect will be longer If this event can not be effectively contained in a short period of time, then extreme depression may seriously affect the price of feed grain, and it is not impossible for CBOT soybean and soybean meal futures prices to break through historical lows China feed industry information network ca8 (author:)
