GALINDO-RENTERIA, Jaime et al. Ferulic acid on productive performance and urinary metabolites of weaned calves. Epistemus (Sonora) [online]. 2021, vol.15, n.30, pp.21-29.  Epub 26-Jun-2023. ISSN 2007-8196.  https://doi.org/10.36790/epistemus.v15i30.173.

This pilot study aimed to evaluate the effect of ferulic acid (FA) supplementation on the productive performance and some of its metabolites in the urine of early weaning calves. Twenty nine calves were randomly distributed in 4 pens (2 pens per treatment). Treatments: control and FA (10 ppm kg-1 live weight) for 30 days. Animal weights were recorded, urine samples were collected at the beginning and end of supplementation, and recorded feed intake daily. The excretion of metabolites in urine was determined by HPLC-DAD. FA did not show an effect on productive performance (p > 0.05). It was not found the presence of AF, trans-isoferulic, or its conjugated in the urine; only excretion of hippuric acid (AH) increased in the group supplemented with AF (282.97µg mL-1) compared to the control group (133µg mL-1). The results suggest that FA could be excreted as HA.
