Results are presented as lsmeans ± SEM. P values of the effects of diet, supplementation, week and the interaction between diet and supplementation, diet and week, and supplementation and week were considered as significant if P ≤ 0.05. Different individual (a,b, c) or group (ac) of letters with no letter in common in superscript indicate significant differences.
