Mean values within a row with the letter (*) are significantly difference (P < 0.05) for comparison between DT and CG. Mean values within a row with different letters (a and b) are significantly difference (P < 0.05) for comparison between DT, DT + ARG, DT + NCG and DT + GLN. Data are stated as mean ± SEM.
