Table 3.

Cross-section structural geometric properties of the femur and tibia were evaluated using micro-CT. Note: Summary of morphometric characteristics in the two groups which were different in body weight-bearing. ^*A statistically significant difference was detected between the two groups only in the trabecular number (Tb.N.) of the femur (p < 0.05) at the age of 20 weeks.
