From;    Author:Stand originally

In the Anhui province that held a few days ago dimensions changed disease of pig farm high fever to prevent and cure integratedly Spring 2008 on new technology seminar, cai Xuehui introduced the main expert that vaccine of disease of La Er of pig of the researcher that comes from institute of vet of Harbin of courtyard of Chinese farming division, our country develops a task how to use vaccine to come in detail defence high fever is ill.
Cai Xuehui says, disease of pig high fever is with the pig breed and breath are asked for integratedly (PRRS) mutation poisonous individual plant is main cause of disease, in coordination one kind when the other factor that cause disease causes in order to last high fever, come on Gao Hechuan of urgent, mortality sows swift and violent the acute that is main and clinical feature, spirited contagion. Preventing virus to send the young hog of lactation by the sow is disease of pig high fever the crucial step in prevention and cure, raise pig door to want to had controlled kind of swinery, child care child pig, leave child care to abandon child pig and before entering kind of swinery mothball kind of pig.
So, how to use disease of high fever of vaccinal defence pig? Cai Xuehui thinks, before immunity, the electronegative pig farm that can be pig farm cent individual plant of poison of mutation of virus of La Er disease and electropositive pig farm, state of popularity of poisonous individual plant of mutation of ill virus of basis blue ear can divide the area that it is epidemic disease and area of blame epidemic disease. Do not suggest in all pig farm of the area that be not epidemic disease use PRRS work is vaccinal (CH - 1R individual plant) , kind swinery can use PRRS to destroy live vaccine. In the electronegative pig farm of epidemic disease area, kind swinery use PRRS destroys live vaccine every 4 milliliter, work of PRRS of immunity of child care pig is vaccinal (CH - 1R individual plant) every 1 portion. The electropositive pig farm of epidemic disease area can be divided for stability / not active pig farm, stable / active pig farm and not stable pig farm 3 kinds. Stable / not active pig farm: Kind swinery use PRRS destroys live vaccine every 4 milliliter, work of PRRS of immunity of child care pig is vaccinal (CH - 1R individual plant) every 2 portion. Stable / active pig farm: The proposal is entire group of immune PRRS work are vaccinal (CH - 1R individual plant) , kind work of swinery immunity PRRS is vaccinal (CH - 1R individual plant) every 3 portion, work of PRRS of immunity of child care pig is vaccinal (CH - 1R individual plant) every 2 portion. Mothball pig is mixed in before hybridization 7 weeks respectively 2 weeks of each immunity 1, every time every 2 portion. Do not stabilize pig farm: Mix to not stable pig farm breaking out this ill pig farm should take PRRS live vaccine (CH - 1R individual plant) urgent vaccinate, can shorten course of diseases, control the amplification of epidemic situation. Kind pig and work of PRRS of fatten pig immunity are vaccinal (CH - 1R individual plant) every 3 portion, work of PRRS of immunity of child care pig is vaccinal (CH - 1R individual plant) every 2 portion.
