Effects of free ferulic acid on productive performance, blood metabolites, and carcass characteristics of feedlot finishing ewe lambs

Abstract: 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 a 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. The feedlot feeding period lasted 34 d and then… Show more

“…Similarly, recent studies also reported that FA acted as a growth promoter in beef cattle (González Rios, Gil Lozano, & Berrondo Mir, ) and pigs (Herrera, Alejo Castillo, & Asaff Torres, ). However, results found in finishing ewe lambs did not support our conclusions because FA‐fed ewe lambs tended to reduce their growth rate (Macías‐Cruz et al., ). The presence of a low oxidative stress in ewe lambs used could help to explain why FA had no effect as a growth promoter.…”

“…Some studies had suggested that FA is a phenolic compound with anabolic effects and antioxidant properties for animals (Gladine, Rock, Morand, Bauchart, & Durand, ; Macías‐Cruz et al., ). In fact, the effects of FA on growth, meat quality and antioxidant capacity had been investigated in heifers, pigs and ewe lambs (Gorewit, ; Li et al., ; Macías‐Cruz et al., ). GIFT fed FA‐supplemented diets in this study tended to show improved growth performance and feed utilization efficiency compared to fish fed the control diet.…”

“…This effect is the reason that phytochemicals like genistein, daidzein, soybean isoflavone and ferulic acid are used in the finishing phase of production animals. However, several phytochemicals have been tested in early stages and have been shown to have an anabolic activity [19–21, 32, 79]. In addition, some studies have proposed two possible mechanisms of action for these results.…”

“…Moreover, recent studies have suggested dietary supplementation with ferulic acid, a member of the hydroxycinnamic acid family that can be isolated from agro-industrial by-products [19, 20, 79], as an alternative to the β-adrenergic agonists that are used in the final phase of intensive fattening of beef cattle. Similar to the effect observed with a commercial β-adrenergic agonist treatment, a 12% improvement in feed efficiency and productive parameters has been observed with the use of ferulic acid in steers [20].…”
