Data is expressed as Mean ± SD (n = 30). Column wise altered superscript statistically implies significant difference (P < 0.05).

TC (daily feeding), T1/1 (1-day feeding/ 1-day starvation), T2/1 (2-days feeding/ 1-day starvation), T2/2 (2-days feeding/ 2-days starvation), and T1/2 (1-day feeding/ 2-days starvation).

LDH, lactate dehydrogenase.

MDH, malate dehydrogenase activity denoted as units/min/mg protein at 37 °C.

⁴

ALT, alanine aminotransferase.

⁵

AST, aspartate aminotransferase activity denoted as IU/L blood.
