摘要
旨在研究中药复方对猪繁殖与呼吸综合征(PRRS)的防治效果以及对母猪生产性能、仔猪健康状况的影响。选择罗牛山某猪场6栋母猪区约4 500头PRRS发病母猪(长白×大约克)作为对照组,每吨饲料添加磷酸替米考星1 kg和复方阿莫西林0.5 kg,自试验开始连续添加7 d;另在发病情况相似的7栋母猪区选择约4 500头同品种母猪作为试验组,拌料饲喂中药复方,每吨饲料添加1 kg九灵甘蓝素和1 kg九灵黄芪素,自试验开始连续添加15 d。检测发病母猪主要生产性能指标、PRRSV抗原、循环阈值(Ct值)及仔猪的出生重、断奶重等。结果:在使用抗生素和中药复方之后,发病母猪中流产数和窝均死胎数明显减少(P<0.05);PRRSV抗原阳性率与发病前相比明显降低(P<0.05);仔猪腹泻率降低但无显著差异(P>0.05),死淘率显著降低,母猪产仔数及窝均健仔数均显著增加(P<0.05),表明中药复方对PRRS的防控效果与抗生素类似;但试验组在8月的流产率、窝均死胎数显著低于对照组(P<0.05),脐带血、睾丸去势液和流产母猪样本抗原阳性率均显著低于对照组(P<0.05),表明中药复方降低了PRRS复发的风险。综上,添加中药复方可降低PRRSV抗原阳性率,减少PRRS的发病率,稳定病情,并能提高母猪的生产性能和仔猪抗病能力。
This study was to determine the effect of traditional Chinese medicine compound on the incidence of porcine reproductive and respiratory syndrome(PRRS)in and the productive performance of sows and the health status of their piglets.The study was conducted on a pig farm in Luoniushan.Sows suffering from Porcine Reproductive and Respiratory Syndrome were fed with antibiotics and traditional Chinese medicine compounds.About 4500 PRRS-infected LY sows in the sow area of 6 buildings on the pig farm were selected as the control group,for which 1 kg of tilmicosin phosphate and 0.5 kg of compound amoxicillin were added to each ton of feed for 7 days continuously from the beginning of the test.At the same time,about 4500 LY sows in 7 other sow areas with similar disease situation were selected as the experimental group,which was fed with Chinese medicine compound,and 1 kg of Jiuling cabbage and 1 kg of Jiuling astragalus were added to each ton of their feed continuously for 15 days from the beginning of the experiment.Then,the major production performance indicators,PRRSV antigen,cycle threshold(Ct value),birth weight and weaning weight of piglets in the control group and the experimental group were detected.The results showed that,after the use of antibiotics and traditional Chinese medicine,the number of abortions and stillbirths in the sows was significantly reduced(P<0.05),and the PRRSV antigen positive rate was significantly reduced compared with that before the onset of administration(P<0.05).The diarrhea rate in the piglets decreased but with no significant difference(P>0.05),and the death rate was significantly reduced.The number of piglets born of sows and the number of healthy piglets per litter were significantly increased(P<0.05),indicating that the prevention and control effect of the traditional Chinese medicine compound on PRRS was similar to that of antibiotics.However,in the experimental group,the abortion rate and number of stillbirths per litter in August were significantly lower than those of the contr
