Data were initially subjected to analysis of variance using a factorial arrangement of time of feeding starter diet, time of commencing finisherdiet, and the interaction of time of feeding starter diet and finisher diet as variables. The General Linear Models procedure of the SAS Institute [11] was utilized in the analysis. After ascertaining that no significant (P≤.05) interactions existed between time of feeding starter diet and time of commencing finisher diet, the main effects of starter diet time and finisher diet time were subjected to regression analysis that tested linear and quadratic models for starter feeding time and linear, quadratic, and cubic models for finisher feeding time. Regression analysis was performed using PROC REG of the SAS Institute. Percentage data were transformed to arc sine and mortality data to square root for analysis. Data are presented in the table as natural numbers.
