If you're thinking of building a new facility for your operation you may want to look into evaporator coolers. For people thinking of putting up new barns, they want to consider putting up an evaporator cooler. What that is, is one wall looks like a radiator and as water runs down the top the fresh air coming in gets cooled by evaporation. Nutrition and a sow's diet are also important when temperatures are high. Adding soybean oil or tallow will add energy to the feed.
Water is critical too.
Thaler says since sows need over seven gallons of water per day you should make sure the flow rate is set correctly. What we recommend is that, that nipple cup water provides three to four cups per minute and I really encourage producers to get a cup into the furrowing room and hold the nipple open and measure it. In 15 seconds the cup should be full if not you don't have enough flow rate in there. The solution to heat stress for sows is to keep them cool by mechanical methods and take a closer look at the nutrition concentration of the feed. This will help your swine herd have a productive summer.
