ABSTRACT: This study investigated the effects of trans-anethole (TA) supplementation on the carcass characteristics, meat quality, fatty acid, and amino acid profiles of breast muscle in broilers. A total of 40 one-day-old male broiler chicks (Arbor Acres) were randomly allocated to 5 treatments, respectively, fed a corn-soybean basal diet supplemented with 0 (control), 200, 400, 600, and 800 mg TA/kg diet for 42 d. 600 mg/kg of TA supplementation decreased (P < 0.05) serum triglycerides (TG) on d 21 and d 42, and high density lipoprotein cholesterol (HDL-C) concentration on d 21, but increased (P < 0.01) serum HDL-C concentration on d 42. Dietary supplementation of TA increased (P < 0.01) the half chamber rate (HCR) and eviscerated rate (ER) of broilers. The drip loss (storing 24 and 48 h) and cooking loss of breast muscle in 600 mg/kg TA groups were lower (P < 0.05) than those in control group. The concentration of palmitoleic acid, daturic acid, oleic acid, linoleic acid, α-Linolenic acid, eicostrienoic acid, and pentosapentanoic acid (EPA), MUFA, and PUFA in the breast muscle were higher (P < 0.05) in the 600 mg/kg of TA group compared with other groups. Dietary inclusion of 600 mg/kg of TA also increased (P < 0.05) the concentration of Met, Thr, Asp, Ser, and Glu in breast muscle, tended to increase (P = 0.069) the Lys concentration. In conclusion, results indicated that TA inclusion improved the lipid metabolism, meat quality, fatty acid composition, and amino acid profile of breast muscle in broilers.
