[en] This study was carried out at 3 pig farm in Hai Duong and Hung Yen provinces from March 2012 to February 2013 to evaluate the reproduction performance of F1(Landrace x Yorkshire) - LY sows mated to three different crossbred boars such as Duroc x ( Piétrain x Duroc) - Pi25, Piétrain x Durroc - Pi50 and Piétrain x (Piétrain x Duroc) - Pi75. Results showed that the reproduction performance of three crossbred boars was high: 10.76, 10.50 and 10.97 pigs born alive per litter; 9.90, 9.91 and 10.04 respectively for Pi25, Pi50 and Pi75. Piglet body weights at birth were 1.36, 1.58 and 1.54kg and body weight of pigs at weaning were 6.39, 6.59 and 6.41kg respectively for Pi25 x LY, Pi50 x LY and Pi75 x LY. Pi50 and Pi75 could be used as terminal sires mated to LY to obtain better reproduction performance.
