Data were provided by a data management company, representing annual production of approximately 1.8 million sows in the United States. Sow-farm traits included pigs per mated female per year, litters per mated female per year, total number born, number born alive, number weaned, preweaning mortality, weaning age, weaning weight, replacement rate, culling rate, sow mortality, lactation-feed intake, and gestation-feed intake. Grow-finish traits included entry age, entry weight, exit age, exit weight, average daily gain, feed efficiency, caloric efficiency, and mortality.

From 2005 to 2010, pigs per mated female per year, litters per mated female per year, number born alive, number weaned, weaning age, weaning weight, and lactationfeed intake increased (P < .05). Sow mortality decreased (P < .05) and replacement rate did not change (P > .05). Entry age and entry weight increased (P < .05) for nursery and wean-to-finish pigs. Average daily gain improved for nursery and finishing production (P < .05), but not for wean-to-finish (P > .05). No improvements were made for finishing caloric efficiency (P > .05), and wean-to-finish caloric efficiency worsened (P < .05). Mortality for both finishing and wean-to-finish operations improved (P < .05).
