PS4-22. Metabolomic Profiling of Serum in Nellore Bulls Supplemented with Guanidinoacetic Acid During the Finishing Phase.
Guanidinoacetic acid (GAA) is the natural precursor of creatine and, as a feed additive, plays a key role in muscle energy metabolism, with positive effects on performance reported in other livestock species. The objective of this study was to evaluate blood metabolic changes induced by GAA supplementation during the...
