... parameters of nonlinear growth functions used for modelling the body weight of farm animals. Gompertz, Brody, Von Bertalanffy and Logistic growth models were employed on the basis of nonlinear least squares and Bayesian methods. Using the monthly body weight data of 2070 weight records of Thalli sheep from birth to 24 months of age for both sexes (male and female) and type of births(single and twin), the estimates of parameters and their credible intervals we...

...ight and growth rate) of growth functions. Analyses showed that the growth profiles of female and male chicks found not to be parallel using profile analysis, and the male chicks had a higher body weight than the females (P < 0.01) starting from 14-21st days until the end of experiment. For this reason, the prediction models were created separately and compared by MAPE (%) and accuracy rate (ρ) criteria in order to find out the most co...

...s of the von Bertalanffy growth functions include growth coeffient (K) = 0.48 year-1, theoretical asymptotic maximum size (TD∞) = 8.2 cm and hypothetical age at length zero (t0)= -0.55 year. The longevity was calculated to be 5.7 years. The natural mortality coefficient was found to be 1.584 year-1. Further detailed studies on biological/ecological parameters of E. mathaei are needed for better unders...
