Growth pattern of crossbred cattle under homoscedastic and heteroscedastic error variance condition

Different growth models are fitted in growth data for Friesian×Sahiwal breed at Agra station. Gompertz model gave better fit than Logistic model. The GLS estimates are found to be more precise than OLS estimates for both Logistic as well as Gompertz model under heteroscedastic error condition.
