Sows were examined 6, and with advancing pregnancy (r2 = 0.99). Sows of from five farms within a single production model that different but related genotypes differed (P 0.01) in included identical feed formulation, management body length, width, height, and depth. Sows of the practices, herd health, and similar, but not identical, same genotype, fed the same feed formulation, dif- genotypes. Sows were individually weighed, backfat fered in body dimensions when managed on different farms. Based on mean values and a 95% confidence thickness was determined by ultrasound, and body
