^*Mean T, treatment; L, linear; Q, quadratic; orthogonal polynomials were used to evaluate linear and quadratic responses to the levels of GS Rg1 treatment. To test the linear and quadratic responses to increases in the Ginsenoside Rg1 level in the diet.

^a−cMean values with unlike letters between different groups were significantly different (P < 0.05).
