This study investigated the effects of citrus extract on growth, carcass and meat quality Duroc × Landrace Large White pigs. One hundred eight pigs (54 barrows, 54 females) were assigned to one three dietary treatments for 138 days. The (1) basic diet; (2) diet supplemented with 75 mg/kg chlortetracycline; (3) (0.25 ml/kg during 56-112 days age 0.20 113-194 age). No significant differences among found growth performance, characteristics, free amino acids (p > 0.05). Feeding tended increase intramuscular fat = 0.052). Citrus chlortetracycline increased C15:0 concentration 0.016) superoxide dismutase activity 0.004). that received exhibited lowest 0.033) muscle malondialdehyde concentration. Overall, ameliorated some indicators without adverse pig or performance.
