3. Data were subjected to the analysis of variance using a factorial arrangement of amino acid concentration, time of change, and the interaction of amino acid concentration x time of change as variables. Mortality data were transformed to square root, and percentage data were transformed to are sine for analysis. The general linear model of SAS [4] was utilized.
