Estimated mud depth and benefits of bedding were simulated under winter environmental conditions. In general, providing greater pen area per animal decreased mud depth. At lower temperatures (16 °F), 250 or 350 ft2 of pen space produced similar depths of mud and approximately 1 inch less than with the 150 ft2 allocations. Under the coldest (16 °F) and wettest (6 inches total precipitation) conditions, cost of gain (COG) was 56.1% ($1.07/lb) greater than with no precipitation falling at 26 °F, while use of bedding reduced COG to $0.80 /lb or just 17.3% greater than COG under more ideal conditions at 26 °F.
