Interpretive Summary:

Technical Abstract: Feeding behavior contains important information that can enable producers to better manage livestock. A study was conducted to quantify these impacts. Data were collected on barrows and gilts (n = 931) from 3 different genetic lines (Landrace x Yorkshire material line with three different sire breeds Landrace, Yorkshire and Duroc) over 4 grow-out periods (2 summer and 2 winter). Pigs were placed randomly in a one of 6 pens in grow-finish barn. Individual animal feeding behavior was recorded with a radio-frequency identification system (RFID). Season, sire line, pen and sex all significantly impacted time spent eating. Pigs spent significantly (P < 0.01) less time at the feeder during the winter compared to summer. Landrace sired pigs spent significantly less time at the feeder than either Duroc or Yorkshire sired pigs. These demonstrate the need to evaluate feeder space allowances for different breeds.
