The effect of dietary supplementation flavonoids from mulberry leaves (FML) on the growth, carcass traits, meat quality, serum antioxidative parameters, and fatty acid profile lipid metabolism skeletal muscle in finishing pigs were investigated present study. A total 120 crossbred F1 barrows Berkshire Bama mini-pig with an average initial body weight (BW) 45.11 ± 4.23 kg randomly assigned to one five treatment groups. Each group consisted six replicates (pens) four per pen. fed either a control diet (FML0) based corn, soybean meal, wheat bran, or 200, 400, 800, 1600 mg/kg added FML (treatments FML200, FML400, FML800, FML1600, respectively). feeding experiment lasted for 58 days after 7-day adaptation period. Blood samples collected 30 (one pig pen) at end this experiment. results showed that increased (P < 0.05) daily gain, lean percentage, loin-eye area, contents C10:0, C18:3n3, n-3 polyunsaturated (PUFA) longissimus lumborum (LL) muscle, activities superoxide dismutase catalase significant linear quadratic pattern. reduced ratio feed intake fat muscular ∑n-6 PUFA/∑n-3 PUFA, malondialdehyde concentration. reduction fiber cross-sectional area shear force LL was observed inclusion Furthermore, mRNA expression levels PPARγ-LXRα-ABCA1 pathway genes related protein abundance modulated by administration. These indicate improved growth performance regulated pigs.
