Abstract: Economic benefits of management information systems (MIS) in sow farming were quantified by combining data from two survey studies. Panel analysis was conducted through estimation of a mixed-effects model by ordinary least-squares. Effects were analyzed both within farms and over farms at the same time, controlling for self-selection bias and changes over time. Adjusted for other effects in the model, production on farms adopting MIS increased by 0.56 piglets per sow per year, indicating a return on investment of between 220% and 348%. Additional tests and checks indicate that this outcome is robust.
