[en] The study was carried out at 3 pig farms in Hai Duong and Hung Yen from March 2011 to January 2013 to evaluate growth rate and carcass quality of F1(Landrace x Yorkshire) (F1(L x Y)) sows mated with F1(Piétrain x Duroc) (PiDu) boars with Pietrain ReHal genetic constitution (25, 50 and 50%: PiDu25, PiDu50, PiDu75). The results showed that these crossbreds obtained high growth rates and low feed conversion ratio (FCR) (829.42 g/day and 2.31 kg/kg; 797.78 g/day and 2.33 kg/kg; 765.79 g/day and 2.38 kg feed/kg weight gain, respectively). Lean meat percentage of
PiDu25 x F1(L x Y), PiDu50 x F1(L x Y) và PiDu75 x F1(L x Y) were 54.66, 56.32 and 59.97%, respectively. Lean meat percentage of PiDu75 x F1(L x Y) was higher than that of PiDu25 x F1(L x Y) and PiDu50 x F1(L x Y). The meat quality traits in terms of pH, colour drip loss, and firmness of 3 crossbreds were normal. Crude protein of musculus longissimus dorsi of crossbreds was 21.53, 22.18 and 22.63%. The research suggests that using crossbed boars PiDu25, PiDu50, PiDu75 to mate with F1(L x Y) sows helps to obtain high performance in pig farms
