Measurements of volume in Göttingen minipigs using a computed tomography scanner

Abstract

We measured the volume in Göttingen minipigs from the CT images of 20 minipigs (11 males and 9 females), and calculated the density and sphericity. The minipigs had been restrictedly fed according to the feeding guideline. The mean ± SD for the density of the 20 pigs was 1.01 ± 0.03; 1.02 ± 0.03 in the males and 1.00 ± 0.03 in the females; no significant sex difference was seen. The mean ± SD for the sphericity of the 20 pigs was 0.606 ± 0.021; 0.593 ± 0.014 in the males and 0.620 ± 0.017 in the females. Sphericity of the females was significantly higher than that of the males（P = 0.002).
