The aim of this study was to evaluate effects of free ferulic acid ( FA: ) supplementation on productive performance, some blood metabolite concentrations, and carcass characteristics of ewe lambs finished in feedlot. Dorper × Pelibuey ewe lambs (n = 20, BW = 28.5 ± 0.5 kg, age = 5 mo) were individually housed in pens and assigned under a randomized complete block design to the following dietary treatments (n = 10): daily feeding without (control) or with 300 mg of FA/animal (FA). The feedlot feeding period lasted 34 d and then all ewe lambs were slaughtered. Free ferulic acid did not affect (P ≥ 0.16) BW gain, ADG, DMI and G:F during the first 17 d, but BW gain (P = 0.10) and ADG (P = 0.10) tended to decrease for FA from d 17 to 34, and from d 1 to 34 without affecting (P ≥ 0.16) DMI and G:F in ewe lambs. Serum concentrations of glucose, cholesterol, triglyceride, total protein and urea, were not affected (P > 0.05) by FA at d 1, 17, and 34 of the feeding period. Carcass characteristics were not affected (P > 0.05) by FA. Stomach percentage tended (P = 0.08) to decrease and leg yields increased (P = 0.02) for FA. Other noncarcass components and wholesale cut yields were not affected (P > 0.10) by FA. In conclusion, FA supplementation did not improve productive performance, metabolic status, and carcass characteristics of ewe lambs receiving a feedlot finishing diet.
