Summary:Production profile concluded from 30 commercial swine herds, using PigLIVE or PigCHAMP database, was presented. Data validation, selection rules and definitions of production indices were throughly described. Statistics on each index were expressed as arithmetic mean, median, standard deviation, range and 95 percent confidence interval. The sign of sub optimum performance was obvious among the herd population in this study. On average, only 17.6 piglets were produced per sow per year while 23 piglets were expected with the maximum biological feasibility. Extensions on procedures to maximize lactation feed intake and proper culling practice may help producers to alleviate the sub optimum productivity. Research on finding the incidence, control and prevention of reproductive diseases deserve funding priority. A fact that the number of breeding females in this study was increasing by 16.5 percent during 1992 may indicate the changing structure of swine production unit toward intensification and specialization.
