^a,b,cMeans within a column with different superscripts are significantly different based on SNK test.

LTT, Lymphocyte Transformation Test; BACT, Bactericidal Activity; LYS, Lysozyme Activity; TAC, Total Antioxidant Capacity; PI, Phagocytic Index; PA, Phagocytic Activity. Number of observations were six per interaction cell. SEM, standard error of the mean.
