The height of each of the laminae of the omasum was measured in 40 especimens of adult Nelore cattle (18 females and 22 males). The laminae were classified as of I, II, III, IV and V orders, according to their decreasing height and their average number was calculated as well as the average  number of cycles (a cycle was considered as the group of laminae centralized by a I order lamina). The average height of the I to V order laminae was 21.77 cm, 6.25 cm, 1.72 cm and 0.05 cm, respectively, in males, and 19.65cm, 11.75 cm, 5.93 cm, 1.94 cm and 0.27 cm, in females. Combining the data of females and males the average number of laminae resulted to be thefollowing: 23.23 cm (I order), 24.25 cm (II order), 44.50 cm (III order), 79.68 cm (IV order), and 23.50 cm (V order). The average number of cycles of laminae was 23.23 cm per organ.
