原始语种摘要: Abstract(#br)In the present study, 43,441 body weight-age records (21,361 records on male lambs and 22,060 records on female lambs) on 6899 lambs descended from 235 sires and 2842 dams that collected from 1991 to 2015 in Kordi sheep breeding station, located in Shirvan city, North Khorasan province, North-eastern area of Iran, were used. Five non-linear models including Brody, Negative exponential, von Bertalanffy, Logistic and Gompertz were fitted on body weight-age data and compared applying Akaike's information criterion (AIC), mean square error (MSE) and adjusted coefficient of determination (R 2 adg ) for determining the most appropriate model describing the growth curve for all, male and female Kordi lambs. The Brody model showed the lowest AIC and MSE and the highest R 2 adg among...
