Abstract
Sow and feeder pig productivity were measured on a random sample of 32 Prince Edward Island swine farms (each producing over 1000 market hogs per year). Productivity parameters could be arranged in a hierarchy, with the highest level on farrow-finish operations represented by pigs weaned per sow per year. The 17 farrow-finish farms in this study averaged 19.6 (+/- 2.2 SD) pigs weaned per sow per year. Large variation between farms was observed with a range from 16.2 to 24.9 pigs weaned per sow per year. The major opportunities for improving productivity, as compared to reviewed targets, lie in reducing the average weaning age, reducing preweaning mortality, and reducing non-productive sow days per parity. The 14 feeder operations were characterized by 0.58 +/- 0.07 kg average daily gain. Average daily gain was negatively correlated with mortality (r = -0.662, p = 0.010), suggesting that herds that achieved a high rate of gain also had lower mortality.
