Summary and Implications
Three, 40-crate farrowing rooms were selected for this comparison study. Half of each room used heat lamps for localized piglet heating while the other half of each room used heat mats. Sixteen turns over 12 months were monitored for power use, piglet mortality, and average weight gain. The only significant impact of either localized heating system was on the power use, where the mats were 36% lower than the lamps.
