Summary and Implications
The objective of this study was to compare two divergent feeding patterns and evaluate their impact on gilt behavior. Eleven gilts were provided ad libitum access to feed (ad lib) and 12 gilts were allowed to eat twice daily (2x). Video of gilt behavior was analyzed 51 days after the start of feed treatments. Gilts fed 2x tended to stand more, spent longer interacting with environmental enrichment, and spend less time eating than ad lib gilts. These results suggest that feeding regimen slightly altered the behavior of individually housed gilts.
