Values are mean ± standard deviation (SD) (n = 10)
Mean followed by different upper case letters (A, B, C, D) in the same columns represent significant difference (P < 0.05) treatment wise
Mean followed by different lower case letters (a, b, c, d) in the same rows represent significant difference (P < 0.05) among study periods (8 weeks)
