Values presented as means () ± SD. Mean values within each row followed by different letters (a, b, c, etc.) are significantly () different. OA, oleic acid; LA, linoleic acid; ALA, alpha-linolenic acid; EPA, eicosapntemacnioc acid; ARA, arachidonic acid; DPA, docosapentaenoic acid; DHA, docosahexenoic acid; TSFAs, total saturated fatty acids, the sum of (C14:0 + C16:0 + C18:0 + C20:0 + C22:0 +C24:0 + ⋯); TMUFAs, total monounsaturated fatty acids, the sum of (C16:1 + C18:1 + C20:1 + ⋯); TPUFAs, total polyunsaturated fatty acids, the sum of (C18:2n-6 + C18:3n-6 + C18:3n-3 + C20:2n-6 + 20:4n-6 + C22:2n-6 + C20:5n-3 + C22:3n-3 + C22:4n-6 + C22:5n-6 + C22:5n-3 + C22:6n-3 + ⋯); S/M/P: TSFA/TMUFA/TPUFA. Different dietary treatments for groups: EG1 (0.8 mL blended oil, 9% palm oil, cholesterol of 0.04 g/kg total diet, and n-6/n-3 9 : 1); EG2 (0.8 mL blended oil, 9% palm oil, cholesterol of 0.057 g/kg total diet, and n-6/n-3 9 : 1); EG3 (0.8 mL blended oil, 8.6% palm oil, cholesterol of 0.04 g/kg total diet, and n-6/n-3 5 : 1); EG4 (0.8 mL blended oil, 8.6% palm oil, cholesterol of 0.057 g/kg total diet, and n-6/n-3 5 : 1); CG1 (0.6 mL blended oil, 6.1% palm oil, cholesterol of 0.04 g/kg total diet, and n-6/n-3 9 : 1); CG2 (0.6 mL blended oil, 6.1% palm oil, cholesterol of 0.057 g/kg total diet, and n-6/n-3 9 : 1). Different proportions of blended oil (g/100 g) for groups: EG1/EG2 (camellia oil 10 g, sunflower oil 74 g, and linseed oil 16 g); EG3/EG4 (camellia oil 18.6 g, sunflower oil 53.5 g, and linseed oil 27.9 g); CG1/CG2 (camellia oil 10.2 g, sunflower oil 73.5 g, and linseed oil 16.3 g).
