A study was carried out at 2 pig farms in Bac Giang province from November 2012 to November 2014 to evaluate the growth rate, carcass and meat quality of (Landrace x Yorkshire - LY) sows mated with Duroc (Du) and Pie train x Duroc (PiDu) boars. The results showed that these crossbreds obtained high growth rates and low feed conversion ratio (736.33 g/day and 2.50 kg feed/kg weight gain, 754.97 g/day and 2.48 kg feed/kg weight gain). Carcass percentage, loin muscle area of the crossbred PiDu(LY) were higher than those figures of the crossbred Du(LY). Lean meat percentage of Du(LY) and PiDu(LY) were 56.32 and 61.74 percent, respectively. Quality of meat of pH, colour, and drip loss of the two crossbreds were within the normal range. The research suggested that using Du and crossbred PiDu boars to mate with (LY) sows helps to obtain high performance in pig farming.
