PL: phospholipid; NEFA: non-esterified free fatty acid; TAG: triacylglyceride; CE: cholesterol ester; RPNfat: retroperitoneal fat, MSCfat: mesocolon fat; SCfat: subcutaneous fat; FA: fatty acid; SFA: saturated fatty acid; MUFA: monounsaturated fatty acid; PUFA: polyunsaturated fatty acid, iso-BCFA iso-branched-chain fatty acid.
Lower-case superscripts within a row with different letters indicate significantly different values (P ≤ 0.05). Significant differences in FA content between horses and ponies are identified by P values ≤ 0.05.
