Comparison of Growth Characteristics of Chukar Partridges (Alectoris chukar) Raised in Captivity

Balcioğlu, M.S., Rizilkaya, K., Karabağ, K., Alkan, S., Yolcu, H.İ. and Şahin, E.2009. Comparison of growth characteristics of chukar partridges (Alectoris chukar) raised in captivity. J. Appl. Anim. Res., 35: 21-24. This study was carried out to estimate growth curve of chukar partridges and to compare the parameter estimates based on Gompertz, Bertalanffy and Logistic models. The growth curve functions were fitted to the observed data individually by using non-linear regression procedure with Marquart algorithm of SAS, NLIN procedure. Gompertz model (with highest determination coefficient and the lowest residual variance) was found to be the best to determine the growth pattern. Sex had significant effect on the estimates of parameter A and weight and age at inflection point within each model.
