Method for preventing and controlling brucellosis of cattle and sheep in large-scale field

Abstract

The invention discloses a large-scale cattle and sheep brucellosis prevention and control method, and relates to the technical field of animal disease prevention and control, and the method comprises the following steps: carrying out brucellosis quarantine on cattle / sheep in the field, eliminating positive individuals, and retaining quarantine healthy individuals; externally introduced cattle / sheep individuals are subjected to isolated feeding, brucellosis quarantine is carried out, and the cattle / sheep individuals are used as quarantine healthy individuals after being qualified in quarantine; cattle / sheep individuals subjected to quarantine health are taken, feeding density is set, and separated feeding is performed; regularly disinfecting the feeding environment; performing regular quarantine and disinfection on the raised quarantine healthy cattle / sheep individuals; and performing regular quarantine and disinfection on newborn cattle / sheep individuals. Different individuals (including local individuals, young animals, adult individuals, introduction individuals, young animals, adult individuals, newborn individuals and the like) in a large-scale breeding cattle / sheep population are subjected to different prevention and control, the prevention and control steps are simplified as much as possible on the basis of increasing the prevention and control effect, and through a large-scale breeding test, the prevention and control effect is good.

Description

technical field [0001] The invention relates to the technical field of animal disease prevention and control, in particular to a method for prevention and control of brucellosis in cattle and sheep in large-scale farms. Background technique [0002] For brucellosis in China, sheep are the main source of infection, and herdsmen or veterinarians take lambs as the main transmission route. Fur, meat processing, milking, etc. can be infected through the skin and mucous membranes, and eating sick meat, milk and milk products can be transmitted through the digestive tract. Long-lasting immunity is not produced, and reinfection after illness is not uncommon. The main source of brucellosis in China is sheep, followed by cattle and pigs. Brucellosis is mainly transmitted by herdsmen receiving lambs, and veterinarians are also very susceptible to infection when delivering sick animals. In addition, skinning cattle and sheep, shearing wool, milking, cutting meat with viruses, slaught...

Problems solved by technology

And in view of the rapid transmission of brucellosis in cattle / sheep flocks, once an individual in the flock becomes ill, it is very likely to cause large-scale individual infection and cause huge economic losses

At present, the prevention and control methods for cattle and sheep brucellosis do not carefully divide the individuals in the population, resulting in different prevention and control effects for different individuals, and ultimately resulting in poor overall prevention and control effects. Such methods are not suitable for small-scale breeding The premise is not enough to reflect the problem. Once it is applied to large-scale farming, there will be more individuals with poor immune control effects, which will inevitably lead to an increase in the disease rate, and economic losses cannot be effectively avoided.
