Abstract :The purpose of study was to compare two different methods to measure the M. longissimus dorsi (MLD) surface area. For this aim, planimeter method and a new method with Autocad software programme were evaluated. MLD areas from 47 samples from Hemşin and Tuj breeds and 63 samples from Saanen, Honamlı and Hair breeds were used. In planimeter method, traced MLD area by hand to acetate paper transferred into squared centimetres. In the new procedure, the surface area of the MLD was traced onto acetate papers and then transferred to a computer by scanning. The AutoCAD software program was used to calculate the area of the MLD. Statistically significant (P< 0.001) correlation coefficients between two methods were detected as 0.999 and 0.998 for Hemsin and Tuj lambs and 0.996, 0.988 and 0.994 for Saanen, Hair and Honamlı kids, respectively. Correlation coefficiant of whole data was 0.995. In the study, there was also found that, time savings can be considered as a notable factor for Autocad method (134.45 second) than the planimeter metod (255.70 second) (P< 0.001). According to findings, the Autocad method can be used as a time saving practical usage instead of planimeter method. Also, this technique can be combined with the some image capturing methods, to reach the reliable results in a short time.
