In a 12-month period beginning in the spring of 1998, a study was run to examine the impact of wet/dry feeders on manure production, manure nutrient levels, and water use in feeder pig barns. This type of feeder is a popular choice in feeder barns. Manure samples were collected every second month from 21 farms. Average water requirement for wet/dry feeder barns was significantly less than dry feeder barns but not average manure production. Manure nutrient levels varied among farms with the average nitrogen content around 0.65% and manure dry matter values for wet/dry feeder barns at 3-11%.
