猪繁殖与呼吸综合征综合防控技术的研究

Abstract

Abstract: In order to explore the synthesis prevention and control technology of PRRS, field investigation, serology monitoring and etiology diagnosis were used to analysis the PRRS sample which occurred in Guizhou province, March, 2007 to October, 2009. Different vaccine immunity effect and newborn pig's female source immune body increase and decrease rule also be researched. The study of serology monitoring and etiology diagnosis indicated that PRRS easy transmit in July to October; the newborn pig and sow's disease infected rate are high, achieves 96.15% and 74.73%; the modified live virus vaccine are superior to killed preparations; the immunity PRRSV sow produces newborn pig's head to exempt the date age to decide as on 17 to 20 d; once infected the PRRSV sow to produce newborn pig to exempt the date age to decide as on 30 to 34 d. Investigated the possibility of the mosquito and fly of carrying the PRRSV in the pig farm and proved that mosquito and fly portable carry PRRSV.

Key words: PRRS; synthesis prevention and control technology
