Growth and reproductive performances of composite breeds PS1 and PS2 at Thai Nguyen plant breeding and aquatic centre
A study was undertaken from January, 2020 to June, 2021 to evaluate the growth and reproductive performances of crossbreds PS1 and PS2 at Plant Breeding and Aquatic Centre in Thai Nguyen province. The growth performances were estimated on 60 PS1 and 60 PS2 gilts. The results illustrated that PS1 and PS2 gilts were high on growth performance from 30 to 100 kg with average daily gain (ADG) at 904.60 and 897.60 g/day, respectively. Reproductive performances evaluated on 20 PS1 and 20 PS2 sows which were mated to PiDu terminal boars over 2 parities shows that both combinations also generated a high reproductive performance. The number born alive (NBA) of PS1 and PS2 sows were 12.65 and 12.78 piglets; The number piglets weaned (NW) were 11.53 and 11.68; and the weaning weight/litter (WW) were 76.81 and 78.81 kg, respectively. In general, the initial results showed that both of composite breeds PS1 and PS2 which were productions of MARD key project “Study on selection of Synthetic dam line and terminal sire line from high performance genetic importation for livestock in Northern provinces” had good growth and reproductive capacity that is suitable for other farms.
