¹Data are expressed as (). Values in the same column with different superscripts are significantly different (). ^uvSignificant () difference between protein levels within the same lipid level. ^xySignificant () difference between lipid levels within the same protein level. LZM = lysozyme; TSOD = total superoxide dismutase; AKP = alkaline phosphatase.
