Abstract Background Modern computer tomography CT equipment can be used to acquire whole-body data from large animals such as pigs in minutes or less. In some circumstances computer assisted analysis of the resulting image data can identify and measure anatomical features. The thickness of subcutaneous adipose tissue at a specific site measured by ultrasound is used in the pig industry to assess adiposity and inform management decisions that have an impact on reproduction food conversion performance and sow longevity. The measurement site called P2 is used throughout the industry. We propose that CT can be used to measure subcutaneous adipose tissue thickness and identify novel measurement sites that can be used as predictors of general adiposity. Methods Growing pigs N 12 were each CT scanned on three occasions. From these data the total volume
