The levels of food intake, body weight gain, liver weight, and serum lipid profile of different feeding groups for a consecutive 30-day experiment including NC (normal diet), HFD (high-fat diet), HFD + P (Xuezhikang, 120 mg kg⁻¹ d⁻¹), HFD + L (PSO, 1.0 g kg⁻¹ d⁻¹), HFD + M (PSO, 2.5 g kg⁻¹ d⁻¹), and HFD + H (PSO, 6.0 g kg⁻¹ d⁻¹). Data were expressed as mean ± SD (n = 6), and means with different letters were different at the P < 0.05 level. Different lowercase letters indicated differ significantly (P < 0.05). ^aP < 0.01, compared with the NC group. ^bP < 0.05, compared with the NC group. ^cP < 0.01, compared with the HFD group. ^dP < 0.05, compared with the HFD group. ^eP < 0.05, compared with the HFD + P group.
