Modification of Process Inputs Using Hog Cooling Pads

Purdue University researchers have developed a low-cost hog cooling pad which uses ground-based water as a coolant for sows in farrowing crates. Initial testing has proven the positive effects of the unit on sow and piglet productivity, but thus far little research has been done on seeing whether or not the use of the pads reduces water consumption by the animals or how much energy is required to operate the units. This study examined data collected during an indirect calorimetry testing program. The limited availability of water sensors hindered the meaningfulness of the water consumption data, but the energy consumption data looked fully plausible. This project will be used to improve data acquisition for these parameters during testing conducted in the future.
