This study aimed at evaluating reproductive performance of 600 grandparent sows (1st-5th parity) of GF24 breed originating from the USA and raising at the pig farm system of GreenFeed Viet Nam Join Stock Company. The data collected from 2.028 litters were imported into the PICTraqsoftware (copyrighted by the Pig Improvement Company, PIC) and then exported to MS Excel as well as Minitab ver 16 software for further analysis. As a result, the total pigs born, total pigs born alive within 24 hours, birth weight, piglets weaned, and weaned weight were 12.43-14.07 heads/litter, 11.85-12.73 heads/litter, 1.40-1.93 kg/head, 11.50-12.60 heads/litter and 5.89-6.91 kg/head respectively. With these high reproductive performance, GF24 sows have gradually adapted with rearing conditions in Vietnam well. It may be considered as a good genetic potential for improving performance of pig breeds now and in the future.
