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...

PS4-21. Serum Metabolomic Changes Induced by Guanidinoacetic Acid Supplementation in Growing Nellore Cattle.

Guanidinoacetic acid (GAA) is a fundamental precursor of creatine, and its role in muscle energy metabolism is of potential importance in growing cattle. The objective was to evaluate blood metabolic changes induced by GAA supplementation in Nellore cattle during the growing phase. The experimental lasted 280 days an...

PS9-2. Association Between Temperament and Serum Metabolomics in Feedlot Nellore Cattle.

Pre-slaughter stress alters systemic metabolism in cattle and can influence physiological processes related to meat quality. Circulating metabolites, such as lactate and amino acids, may reflect metabolic responses to stress and energy metabolism. The objective of this study was to evaluate the association between ca...
