The reproductive cycle is 158.33 day averagely. 2.31 litters were farrowed per sow each year. The litter size is 16.35. The piglets born alive are 15.10 per litter. The weanling pig is 14.44 at the age of 35 day. The weaning weight of litter is 83.48 kilogram. 37.69 piglets were reproduced per sow per annum.34.81 piglets were born alive per sow per annum.
