Quadra runs a new 7-week nursery program. Four different feeds are fed to the nursery pig over the course of the 7 weeks. Two are fed in the first week by hand. Over the next 6 weeks, two separate chain disk or cable drive systems provide automated feed delivery. The feeders are Crystal Springs stainless steel dry feeders. The flooring is totally slatted plastic flooring with PVC plank penning. Water is supplied to the pigs through stainless steel nipple drinkers and adjustable drops. Ventilation is designed as a negative pressure system. The inlets are installed on the bottom of ducts that lead from a pre-heat plenum. For summer time ventilation, flaps on the top of the duct are opened to allow air directly into the duct and increase the make-up air supply capacity. Heating is primarily provided through gas-fired unit heaters or radiant tube heaters. Two facilities use Hydronic heating systems. One is fired with a coal boiler. All walls are at least 2 feet above finished floor height on a concrete grade beam. All ceilings are 10’ high. Typically the ceiling is painted plywood with either PVC planking as walls or fiberglass covered plywood.
