(1) Compared with the basal diet, a high-fat diet significantly increased the abdominal fat percentage in broilers (P < 0.05), while bile acid supplementation significantly reduced abdominal fat percentage (P < 0.05). Compared with diets without bile acids, dietary bile acids supplementation significantly increased breast muscle and thigh muscle percentages in broilers (P < 0.05).(2) Compared with broilers fed the basal diet, those fed a high-fat diet exhibited larger and more densely arranged adipocytes in abdominal fat sections. However, dietary bile acid supplementation significantly reduced adipocyte size in abdominal fat. The high-fat diet significantly increased the perimeter and area of adipocytes in broiler abdominal fat compared with the basal diet (P < 0.05), while bile acids supplementation significantly decreased these parameters (P < 0.05).(3) Compared with diets without bile acids, dietary bile acids supplementation significantly reduced the PH24h value of breast muscle (P < 0.05) and significantly increased the yellowness (b*) of breast muscle (P < 0.05). In addition, bile acid supplementation significantly decreased the 45-minute and 24-hour pH values of thigh muscle (P < 0.05).(4) Compared with broilers fed diets without bile acids, those supplemented with bile acids showed significantly higher intramuscular fat content in both breast and thigh muscles (P < 0.05).
