Values are means ± SDs. Significance was set at P < 0.05. Categories in the same row that do not share the same superscript letters are significantly different. LP-0.015P, 10% protein and 0.015% P; LP-0.056P, 10% protein and 0.056% P; LP-0.1P, 10% protein and 0.1% P; LP-0.3P, 10% protein and 0.3% P; NP-0.3P, 20% protein and 0.3% P (control group).
