NS: not significant, PS: protein source, A: adaptation. a Two way ANOVA; b GI: gastrointestinal, Incorporation in stomach, small intestine, cecum and colon; c Incorporation in liver and plasma protein; d Incorporation in hepatic pools, GI tract and kidneys; e Incorporation in muscle and skin. Means in a row with different letters are significantly different (P < 0.05, Tukey post-hoc test).
