Abstract: The linear and quadratic models were used to estimate growth of live weight and body measurements in Anatolian Merino male lambs from weaning (75 days) to 145 days of age. Lambs were fed for a 63 days feeding period after a week of adaptation period. The feed contained 2775 kcal/kg metabolic energy and 15 % crude protein. Both of the models showed good fit to the live weight and leg girth data (R2=0.990 and 0.984). The quadratic model gave a better fit to withers height, rump height; chest girth, chest depth and body length data and allowed a suitable description of growth curve by its higher R2 and lower MSE values (P<0.01).
