Replicate means for BW, BW gain, feed conversion, and percentage mortality and liver and gallbladder weights were analyzed by one-way analysis. The effects of treatment on mortality, BW, BW gain, feed conversion, and relative organ weights were analyzed separately at each specified age and age interval. A randomized complete block experimental design was used in Trial 2. Replicate means were analyzed by a two-way split-plot analysis with treatment as the whole-plot factor and day of broiler age as the subplot factor. This method allowed testing for the effects of treatment, day, and their interactions on BW, body temperature, and percentage mortality. The effect of treatment on BW gain between 0 and 6 d was tested by one-way analysis. Angular transformations (arc sine of the square root of the proportion affected) were performed on all percentage data prior to analysis. Means were compared by least square means [8]. All data were analyzed using the general linear models procedure of SAS Software [9]. Statements of significance were based on P ≤ 0.05, unless otherwise indicated.
