Description

A boil material device for preventing and control African swine fever

Technical Field

The utility model relates to a pig feed cooking equipment, concretely relates to a boil material device for preventing and controlling African swine fever.

Background

African swine fever was first discovered in kenia in africa in 1921, was named as african swine fever because clinical symptoms are highly similar to traditional swine fever, and was first discovered in africa. The African swine fever is an acute, hot and highly contact animal infectious disease, pigs of all varieties and ages can be infected, the morbidity and the mortality can reach 100 percent at most, the world animal health organization classifies the African swine fever as a legal report animal epidemic disease, and China classifies the African swine fever as a class of animal epidemic disease and is an important foreign disease for prevention and control. The main transmission route of African swine fever is that healthy pigs are directly contacted with sick pigs or pollutants (such as air, feed and drinking water), and the pigs are bitten by vector insects such as tick with virus, so that the infection possibility exists.

The feed and the drinking water are used as the only living necessities of the pigs, and the possibility of virus contact transmission exists inevitably, so that how to disinfect the feed and the drinking water is very important. Research shows that the African swine fever virus is high in low temperature resistance, the virus still has infectivity after being stored for 6 years in refrigeration, can survive for more than 1 year in an environment at 4 ℃ and can survive for several weeks in an environment at 25-37 ℃, the freeze-dried virus can be guaranteed not to be damaged for 15 days or 3.5 hours at 40 ℃ or 50 ℃, but can be inactivated 70min after being heated to 56 ℃, and can be inactivated at 60 ℃ for 20 min. In addition, the literature reports that the growth performance of the pigs can be obviously improved by feeding the pigs with the wet mixed feed, and the effect of feeding the pigs with the wet mixed feed with the water-feed ratio of 4:1 is the best.

At present, a part of pig farms use a boiling device to boil materials, a boiler is usually used for directly heating clean water from the bottom, and then the feed is added, but the material boiling mode easily causes the problem that the mixing uniformity of the feed and the water is not enough, meanwhile, the feed is not uniformly heated, part of the feed cannot be heated, the propagation of African swine fever viruses cannot be prevented and controlled from the aspect of drinking water, and meanwhile, the mode easily causes energy waste, a large amount of heat is dissipated during heating, and the processing cost is increased.
