The data were subjected to statistical analysis with SPSS to determine if variables differed between groups. The Kolmogorov-Smirnov test was used to test the normal distribution of the data before statistical analysis was performed. Microbial colony count and intestinal histomorphology were compared between groups by general linear model two ways ANOVA and subsequent Duncan’s 6 multiple range tests. Probability values of less than 0.05 (P < 0.05) were considered significant. Results are expressed as means ± pooled SEM.
