Article Synopsis
- Ferulic acid (FA) is a natural compound being studied as a possible alternative to synthetic growth promoters in livestock, particularly in hair-lambs.
- In a 32-day experiment with 32 male lambs, two different doses of FA (300 mg and 600 mg daily) were compared to a synthetic compound, zilpaterol hydrochloride (ZH).
- Findings showed that FA improved overall weight gain and muscle fiber characteristics, while ZH notably increased muscle area and gene expression related to muscle growth, suggesting both have potential for enhancing growth in lambs.
Theoretically, a positive environment (PE) includes (a) tangible and intangible resources that satisfy human needs, (b) enablers of healthy, pro-social, and pro-environmental behaviors that guarantee socio-environmental quality and wellbeing, and (c) environmental challenges that must be faced and solved. One of the most salient challenges is the global COVID-19 pandemic. This study sought to investigate whether PEs can stimulate responsible actions (i.

The present study aimed to evaluate the impact of two doses of ferulic acid (FA) on the feedlot performance, carcass traits, and physicochemical and sensory characteristics of meat quality in commercial heifers. Ninety heifers (3/4 Bos taurus; n = 270; body weight = 480 ± 10 kg) were randomly assigned to one of the following treatments (30 days): Control, fed with a basal diet; FA250 or FA500 offered the same diet further supplemented with FA at 250 or 500 mg kg feed, respectively.
