Abstract: The production data were recorded by computer software in large-scale pig farms, and the collected data were timely inspected. The management of pig farms with computer software increased the number of listed pigs given birth by each sow as well as the production performance of sow. As shown by the survey, the delivery rate reached 78.55 % in 2007, 11.61% higher than in 2006. The birth interval was 154.3 d, 23.75 d shorter than in 2006. The number of weaning healthy piglets was 23.20, 3.77 piglets more than in 2006.
