a − cValues with different superscripts differ significantly (P < .05) in the same row; “a”, “b”, “c” indicate significant difference from each other while “ab” is not significant. Values are mean ± SD for 10 laying hens per group. Differences were tested by Duncan multiple range test. HDL = High density lipoprotein; LDL= Low density lipoprotein.
