Özet
This study is aimed for estimation of variation of growth by time as the form of several growth curves of the data of Karacabey Merinos x Kivircik crossbred lambs raised in Tekirdag province of Turkey. The Gompertz, Logistic and linear models were used to evaluate the best fit model. The best model was selected according to the values of determination coefficient (R-2) and sum of squares of differences between observed and estimated values obtained as average live weights of lambs and values obtained by equation of interest for the same period of growth respectively. Data were divided three groups according to sexes and general groups. Sum of square differences were found 3,14 (Gompertz model), 4,47 (Logistic model), 4,73 (Linear model) for female lambs. Similarly sum of square differences were found 7,06 (Gompertz model), 15,83 ( Logistic model), 15,85 (Linear model) for male lambs.
