Major differences were observed between the two farms. This analysis indicates that realtime ultrasound can be used to develop lean and lipid accretion curves for formulating farm-specific diets that optimize lean growth performance in commercial operations.SwineUltrasoundGrowthModelingPerformanceConference paper
