Plain-English summary
Researchers studied a large pig farm for two years to see how well the pigs were reproducing and how many young pigs (weaners) were being produced. They used a computer program to analyze the data and conducted monthly farm inspections and quarterly checks on any pigs that died. By making some controlled changes in how the farm was managed, they found that the number of piglets each mother pig raised in a year increased from about 15 to 17, and the average weight of the piglets at eight weeks old improved from around 10 kg to 15 kg. Overall, the changes made a positive difference in the farm's production.
Abstract
A computer program was used to analyse data from a large commercial pig unit over two years to assess reproductive efficiency and the efficiency of weaner production. Monthly inspections of the farm and quarterly post mortem examinations of all dead pigs provided further information. The effects of controlled changes in management on production were assessed. Overall the number of piglets reared per sow per year was increased from 15-1 to 17-2 and the eight-week weights improved from a mean of 10-3 kg to 15-0 kg during the two year-study period.
