Effects of different dietary fat/oil on FER and body weight and body fat accumulation. Mice were fed different dietary fats/oils: lard, sunflower oil (SFO), soybean oil (SBO), lard blended with SFO (L-SFO), and lard blended with SBO (L-SBO). a Feed efficiency ratio (FER) = [weight gain (g)/food intake (g)] × 100; b initial body weight; c Final body weight; d epididymal white adipose tissue (WAT); e perirenal WAT; f body fat mass = epididymal WAT weight (g) + perirenal WAT weight (g); g body fat rate; =[epididymal WAT weight (g) + perirenal WAT weight (g)]/final body weight× 100; h cross-section area (CSA) of epididymal adipocyte; and (i) section of epididymal adipose tissue stained with h and e. Data were expressed as mean ± standard error of the mean, n = 9–10 per group except for (a), (h) and (i), n = 5 per group. Values with different superscript letters (a, b, c, and d) are significantly different at P < 0.05
