REPRODUCTIVE PERFORMANCE OF CROSSBRED SOWS (♀YORKSHIRE X ♂LANDRACE) AND GROWTH RATE OF CROSSBRED PIGLETS BETWEEN DUROC X (♀YORKSHIRE X ♂LANDRACE) AND PIDU75 X (♀YORKSHIRE X ♂LANDRACE)

Abstract

The study was conducted in Hoa Binh livestock breeding center, to evaluate the reproductive performance of crossed sows F1(YL) mated with Duroc and PiDu75 boar. In addition, the experiment also investigated the performance of piglets to 60 days old. Results showed that the litter size and body weight at farrowing and at weaning are 11.47 – 11.78 piglets/litter; 1.38 – 1.39 kg/piglet, and 9.44 - 10.21 piglets/litter; 7.45 – 7.75 kg/piglet weaned, respectively. The growth performance of weaned pigs of increasing weaning weight at 25.07 to 25.68 days of age reached 7.45 – 7.75 kg/pig. The two hybrid subgroups ♂Du x ♀F1 (YL) and ♂PiDu75 x ♀F1 (YL) have the ability to grow and develop well in both the mother and weaning stages. Pigs of the hybrid formula ♂PiDu75 x ♀F1 (YL) had better growth in both. Overall, results indicated that improved crossbred F1(YL) basic sows mated to the Duroc and PiDu75 may become effectively in both technique and economic concept for pig meat production in Hoa Binh province.
