Villus surface area (VSA) is measured to reflect the active absorption surface of the intestine under different experimental conditions. In context, it has been recommended to use a suitable model for calculating VSA of different shapes. However, no more attention has been paid to this point. Thus, a mathematical model, to calculate the VSA of ridge-like shape villi, was proposed for increasing the accuracy of VSA measuring. Then, to test the proposed model, a comparison between the common (tube-like) and proposed (ridge-like shape) models was done using real 416 villi morphometrics (height and width) of one-day-old specific pathogen-free broiler chicks. Also, Python program® was used to do a microcomputer simulation for comparing between models. Statistically, the apex surface area of the tube-like shape was greater than that of the ridge-like shape (P<0.0001). While the total VSA of tube-like shape villus was numerically greater than this of ridge-like shape ones. These results were confirmed by the simulation study. In conclusion, since the villus shape affects the VSA, the proposed model can be recommended for calculating the surface area of the ridge-like shape villi instead of the common ones. Besides villus morphometrics, the villus shape-surface area relationship can be used to explain the changes in absorption capacity and related economic parameters such as growth rate and body weight under different experimental conditions.
