Deep bedded housing is becoming more popular as a confinement option. Besides taking less space than sheltered open lots, the rate of gain is comparable and runoff isn’t an issue. The costs of building tend to be less than slotted floor confinement, although there tended to be slightly less nutrients maintained in the bedded manure versus the pit waste. The chart below uses data from Purdue ID 101 to show the difference in nutrients lost in the manure in different housing systems.
