Diagnosis of sow lameness using the microcomputer-based force plate system and pattern recognition methods
April 8, 2015By Kenneth J. Stalder
Sow longevity is a key component to breeding herd profitability. Lameness is a major reason for culling and therefore can negatively impact sow longevity. Lameness assessment in group housing...

The impact of the timing of relocation of replacement gilts from pens to stalls on gilt fertility and sow longevity
February 23, 2015By Robert V. Knox
This research addressed uncertainties involving the effects of the timing of transition from pen housing to stalls on replacement gilt fertility and longevity. In most US farms, replacement gilts are...

Evaluation of a Physiological Test for Sow Longevity
June 4, 2014By W. L. Flowers
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...

Development of Strategies to Improve Sow Productive Lifetime
June 1, 2014By Jason W. Ross
Numerous factors, including herd-life (length in days), removal parity, total piglets born and the number of piglets weaned, impact sow productive lifetime. Like many complex traits that are...
