Fact Sheet Number
One of the factors that influence feed efficiency is how pigs access feed via the feeder. Feeder design primarily impacts feed efficiency by affecting the pigs’ access to feed and feed wastage. Gonyou and Lou (1997) tested 12 feeders and found that all 12 feeders had wastage of less than 5%; smaller pigs wasted more feed (4.4%) than larger pigs (2.4%).
