Moisture Production of Grower-Finisher Pigs: Field Measurements Compared with Theoretical Values
To select the optimal minimum ventilation rate, moisture production equations have to be verified for intensive swine operations for Canadian climates. Under-ventilation leads to high humidity levels and bacterial growth, while over-ventilation increases the cost of heating in the winter. Moisture production levels were measured and compared to predicted values to see if the equations used are valid in Canadian climates. Additional work needs to be done to update the moisture production equations to represent actual conditions as the best average values had an 8% difference.
