猪蓝耳病背景下不同综合防治措施对母猪断奶7 d发情率的影响

Effects of Different Integrated Control Measures on Oestrus Rate of Sows Weaned for 7 days under the Background of Porcine Respiratory and Reproductive Syndrome

为了解母猪在受猪蓝耳病威胁下,采用不同的综合防治措施对其7 d断奶发情率的影响,该研究采取比对试验的方法,对受猪蓝耳病不同程度影响且均出现断奶发情率降低的2个规模相同的养殖场A场和B场,采取不同的综合防治措施:A场主要使用中药芪霍散(主要成分:刺五加、女贞子、越橘、鱼腥草、人参、杜仲等)+抗生素和B场则采用中药芪霍散+20%替米考星+营养补充+精细管理。结果发现,与A场相比,B场采取“中药+抗生素+营养补充+精细管理”的防治措施后,母猪断奶发情率逐步恢复且趋于稳定。

In order to understand the effect of different integrated control measures on oestrus rate of sows weaned for 7 days under the threat of Porcine Respiratory and Reproductive Syndrome,comparative test was adopted in this study,two farms of the same size,A and B,which were affected by Porcine respiratory and reproductive Syndrome in different degrees and had similar estrus rate reduction at weaning,different integrated control measures were adopted:Qihuo San(main ingredients:Acanthopanax senticosus,Ligustrum lucidum,Blueberry,Houttuynia cordata,Ginseng,Eucommia ulmoides,etc.)+antibiotics was used in Farm A,and Qihuo SAN+20%Tilmicosin+nutritional supplement+fine management”was used in Farm B.The results showed that,compared with Farm A,the estrus rate of piglets in Farm B recovered gradually and tended to be stable after taking the preventive and control measures of“Traditional Chinese medicine+antibiotics+nutritional supplement+fine management”.
