The purpose of this study was to quantify and mathematically describe the differential growth and development of body components of live pigs. Linear and non-linear models were developed to evaluate the patterns of growth and development of each body component realtive to the computed tomography (CT) BW. The results of this study indicate that the nonlinear (e.g. augmented allometric and generalized nonlinear) functions provided better descriptions of the growth and development of most body components of the live pig than did the simpler (e.g., linear and allometric) models.
