发酵床模式下保育猪弓形虫病防治效果研究

Studa on Control Effect of Toxoplasma Gondii in Pigs Under Fermentation Bed Mode

某发酵床模式自繁自养猪场,仔猪断奶后每批次均有消瘦、腹泻、呕吐、神经症状等临床症状发生,造成了一定的损失。根据临床症状、剖检变化、病原检测以及血清抗体检测,诊断为猪弓形虫感染。通过制定和实施以磺胺类药物为主,辅以加强生物类媒介(猫,狗,鼠)管理,垫料堆积发酵等防治手段,成功控制了疫情。经过为期1年的预防措施的实施,后面批次的保育猪未复发,且母猪和仔猪的猪弓形虫血清抗体阳性率普遍下降,说明制定和实施的发酵床模式下猪弓形虫防治方案合理有效。

One pig farm is a self-bred pig farm and is fermentation bed model.Every batch of weaned piglets has clinical symptoms such as emaciation,diarrhea,vomiting and neurological symptoms,which cause certain losses.Toxoplasma gondii infection was diagnosed by clinical symptoms,examination,pathogen detection and serum anti⁃body detection.The epidemic was successfully cured by formulating and implementing procedures for the treatment and prevention of sulfonamides,strengthening the management of biological vectors(cats,dogs,mice),and accumula⁃tion and fermentation of pads.After 1 years of preventive measures,there was no recurrence of pigs in the latter batch,and the positive rate of Toxoplasma antibodies in sows and piglets decreased generally.This indicates that the prevention and control plan of Toxoplasma gondii under the fermentation bed mode is reasonable and effective.
