Effects of Preweaning factors on Sow Lifetime Productivity

     The objective of the study was to associate preweaning factors in gilt multiplication with the subsequent lifetime productivity of females in commercial sow herds. Sows were farrowed at two Smithfield Hog Production multiplication farms located in North Carolina between…

Evaluation of a Physiological Test for Sow Longevity

A gilt’s response to early boar exposure has been shown to be a viable option for estimating her lifetime productivity as a sow. Unfortunately, providing adequate boar exposure at young ages poses several practical and biosecurity issues for many multiplication…
