Fifteen years of data from a flock of Bergamasca sheep weighed every two weeks was analyzed using non-linear methods to determine parameters of three growth curves (Brody , Richards and Logistic). The curve parameters were analyzed using Statistical Analysis System (SAS) procedures GLM and CORR to determine factors which influenced them and correlations between the parameters and weights at determined ages. Fixed effects in the model included lambing number, sex of lamb, type of birth and month and age of […]
