猪瘟控制(净化)对母猪分娩率的影响

目的：通过对某猪场母猪实施猪瘟控制（净化）方案，研究分析能否提高该猪场的母猪分娩率。方法：采用酶联免疫吸附试验（ELISA）对龙岩市某规模化猪场的母猪进行猪瘟抗体检测，对猪瘟抗体检测不合格（阻断率小于40%）且同时满足两条及以上淘汰标准的种猪实行淘汰以达到猪瘟控制（净化）目的，并对猪瘟控制（净化）前后配种分娩结果进行收集、统计。结果：猪瘟控制（净化）后，母猪返情、流产、空胎数量减少，分娩率明显提升。结论：猪瘟控制（净化）可以提高母猪分娩率，实行猪瘟控制（净化）对规模化猪场具有重大意义。

Influence of Controlling （Eradicating） Classic Swine Fever to Sow Parturition Rate in a Large Scale Pig Farm

Objective：Investigate and analyze whether the sow parturition rate could be improved by controlling （eradicating） classic swine fever in a large scale pig farm. Method：The antibodies of classic swine fever of sow were detected with Enzyme-linked immunosorbent assay （ELISA） on a large scale pig farm in Longyan city. The sows which the antibodies of classic swine fever were below standard were sifted out controlling （eradicating） classic swine fever. The data of the sow parturition rate were analyzed before controlling （eradicating） classic swine fever and after. Results：The numbers of the sows which showed returning to estrus, abortion and non-pregnancy have reduced and the sow parturition rate was improved obviously by controlling （eradicating） classic swine fever. Con-clusion：Controlling （eradicating） classic swine fever can improve the sow parturition efficiency. It is of a great sig-nificance for a large scale pig farm to control （eradicate） classic swine fever.
