Method and primer for identifying farrowing performance of French landrace

The invention discloses a method and primer for identifying farrowing performance of French landrace. The invention further discloses a primer for amplification of FSHR 91773610 C>T, MEP1A 41617218 G>T and PLA2G4A 128109061 T>C and a method for detecting, analyzing and identifying the farrowing performance of the French landrace by using the primer. According to the primer and the method, early breeding of sows with high farrowing performance can be realized, the number of the total farrowing, live farrowing and healthy farrowing of landrace is increased, the feeding cost is saved, and the breeding time is shortened. The method is simple to implement and convenient to operate, and has very high practical application value. 本发明公开了一种鉴定法系长白猪产仔性能高低的方法和引物。本发明同时也公开了FSHR 91773610 C>T,MEP1A 41617218 G>T,PLA2G4A 128109061 T>C扩增的引物及利用该引物进行检测、分析和鉴定法系长白猪产仔性能高低的方法。此引物和方法可以实现母猪高产仔性能的早期选育，提高猪的总产仔数、产活仔数和健仔数，节省饲养成本，缩短选育时间。该方法实施简单，便于操作，具有很高的实践应用价值。
