TABLE 5.

Summary statistics for two linear mixed effects models testing the influences of diet and sex on bactericidal capacity againsted (1) Escherichia coli and (2) Salmonella paratyphi before and after the experimental diet was started. Bactericidal percentages were arcsin transformed for analysis. Diets included a “natural” diet that mimics what white ibis eat in the wild and an “anthropogenic” diet, which is higher in carbohydrates and lower in protein. There was a significant diet x time interaction effect on bactericidal capacity against S. paratyphi
