Double Sided Grower/finishing Feeder: Two-stage finish feeder. All welded construction, made from 304 Stainless Steel for many years of trouble-free use. The two-stage feeder helps to avoid feed waste due to spoilage and animals dragging feed from the trough. The primary eating surface is on a raised deck above the trough bottom, which eliminates the build-up of feed in the bottom. Since there will be very little feed in the trough, hogs can not drag feed out onto the floor and if the animals deposit waste in the trough, there will be no spoiled feed. Less wasted feed equals lower feed to gain ratios, and that equals more profit for you.
