What is piglet? Misunderstandings in the prevention and control of swine fever and its control strategies

What is swine fever? Pork chop can also be called rotten intestinal tract, pig cholera, etc. It is caused by the swine fever virus of the genus Rhodopsin, which is an acute, contact, and febrile infectious disease. Under natural conditions, pigs of all ages and varieties can be harmed. It can be said that piglets are one of the major infectious diseases that threaten the pig industry. However, in the actual prevention and control measures, there are still many misunderstandings. Therefore, today Xiaobian talks about the misunderstandings and prevention measures of piglet prevention and control.

First, the misunderstanding in the prevention and control of swine fever

1. Cognitive misunderstandings of farmers, thinking that farming does not require too much management

(1) In many places, the decentralized breeding mode is still adopted, and the farmers are not aware of the pig breeding. In order to save the cost of breeding, some pigs are built as semi-open, and the pig house is poor in safety and hygiene. Insufficient degree, some farmers after the purchase of foreign piglets, do not isolate the breeding for a period of time, they will directly mix these piglets and their own piglets, increasing the incidence of piglets.

(2) During the busy season, farmers will focus on farming, thus neglecting the prevention and control of swine disease and increasing the spread of swine fever virus.

2. There is a misunderstanding in immunization work

(1) Rural free-range pigs lack scientific immunization procedures, and the dose of immunization is insufficient, which increases the hidden dangers of swine fever.

(2) In the process of breeding, there was no epidemiological investigation, and immunization was carried out step by step, which made the immunization program of the farm inconsistent with the actual situation in the local area, resulting in unscientific immunization procedures.

(3) There is no scientific management of vaccine transportation and preservation, which leads to the inactivation of the virus in the live vaccine, and the reduction of the immune dose, which makes the immune failure phenomenon.

(4) Insufficient professional skills of epidemic prevention workers, often caused by improper operation and insufficient dose of immunization vaccine, resulting in immune failure.

3, epidemic prevention, quarantine work is not in place

(1) The professional level of epidemic prevention personnel is not high, and the professional knowledge of animal husbandry and veterinary medicine is insufficient, which has adverse effects on epidemic prevention and quarantine work.

(2) Farmers have a low awareness of epidemic prevention, and pigs carrying pathogens enter the area, resulting in the prevalence of swine fever.

(3) In the work of pig epidemic prevention and quarantine, the relevant departments have weak suggestions.

Second, the prevention and control of swine fever

1. Strengthen daily routine prevention

(1) In the process of breeding, strengthen daily prevention, establish a sound sanitation and epidemic prevention system; strictly isolate, purify and disinfect the entering personnel and vehicles; avoid pigs carrying pathogens when purchasing pigs, and increase the chance of pigs infected with pigs .

(2) When the humidity is high, the concentration of ammonia is high, which is easy to cause diarrhea in pigs, which provides a hotbed for the occurrence of swine fever. Therefore, the humidity of the pig house should be controlled according to the actual situation.

(3) In the pig house, the feces and excrement contain a lot of bacteria, so it is necessary to clean up the feces in time, reduce the pathogen pollution, and effectively prevent the occurrence of swine fever.

2, strengthen vaccine immunity

(1) The individual farmers of pigs, spleen and spleen seedlings were injected into the pigs. At present, there are four kinds of swine fever vaccines commonly used in China: spleen seedlings (I), milk rabbit seedlings (I), cell seedlings (II), and Lianmiao.

(2) spleen seedlings, milk rabbit seedlings, cell seedlings are single piglets, and the combined seedlings refer to the piglet- erysipelas-pulmonary epidemic triple seedlings, or the swine fever- erysipelas double seedlings.

(3) In the emergency immunization of swine fever vaccine, the tissue seedling is more appropriate and more effective than the cell seedling, especially the lymphokines in the spleen seedling, which plays a more rapid role in immunity.

3, strengthen the prevention of piglets prevention knowledge

(1) Grassroots epidemic prevention stations should organize personnel to carry out propaganda of hog mites and improve the awareness of epidemic prevention among farmers.

(2) Do a good job in daily epidemic prevention, improve the prevention and control level of piglets, and improve the economic benefits of farmers.
