The top floor has individual stalls for the bucks. The lower walk out level has large rooms for the does. Each stall has two floors, the top floor collects the feces pellets. The bottom floor collects the urine. The bottom floor is made of stainless steel beveled in two directions to allow the urine to drain into a container in a cooling pit.
Feces is full of bacteria.
Urine is sterile, but becomes contaminated when it is excreted. This 'clean' urine is cooled to decrease the opportunity for bacterial growth, thereby allowing it to maintain its freshness. The deer are put in these stalls in the evening and then let out in the morning to allow them to be on natural pasture and exercise. The entire facility is cleaned with high pressure water daily then dried with powerful fans. The patented freeze drying process preserves the pheromones and leaves the molecular structure unchanged until it is rehydrated.
