Effect of Lp. plantarum FRT4 on glycerophospholipid metabolism-related factors in liver. The results were expressed as the mean ± SEM; n = 6 hens per group. * means the significant difference of HELP compared to CT group, and * means P < 0.05, ** means P < 0.01. # means the significant difference of FRT4L, FRT4M, and FRT4H compared to HELP group, and # means P < 0.05, ## means P < 0.01, ### means P < 0.001. CT: control group, hens fed with normal diet. HELP: model group, hens fed with high-energy low-protein diet. FRT4L, FRT4M, and FRT4H: experimental groups, hens fed with high-energy low-protein diet with 109 CFU/kg, 1010 CFU/kg, and 1011 CFU/kg Lp. plantarum FRT4, respectively
