This study was performed to make helpful standard for discrimination of cows from heifers by uterine and ovarian section inspection. A total of 3,736 heifers and 249 cows were inspected from January to November 2006 in Karak Market Slaughter house. Firstly, it was obvious that noncorpus albicans were observed in almost heifers(3,597/3,736, 96.3%), but there were distinctive corpus albicans in all cows(249/249 100%). Secondly, another evident was that the length and diameter of the horn in uterus was below 30㎜ in 94.5%(3,267/3,736) heifers, but above 30㎜ in 90.4%(225/245) cows, and it was easy to distinguish between right and left horn by difference of size in 87.6%(218/249) cows. Thirdly the diameters of pelvic cavity was below 220㎜ in 96.8%(3,615/3,736) heifers, but was over 200㎜ in 85.1%(212/249) cows. Fourthly another difference was found in second sacrum union condition and 13th thoracic vertebral process's states. In case of heifers, it was distinctive five lines in each second sacrum, but it was nondistinctive or united in the same each lines of the sacrum in cows. Fifthly in the results of 13th thoracic vertebral colors, the ratio between*Corresponding author:Phone: +82-2-570-3236, Fax: +82-2-570-3206E-mail : city1004@seoul.go.krred color and white color was 7:3 in heifers(3,385/3,736, 90.6%), but that was 2:8 in cows(199/249, 79.9%). Consequently, it was possible to use the method which discriminated cows from heifers by uterine and ovarian section inspection in large scaled field slaughter house.
