Stepwise approach applied to metabolites related to residual feed intake in Angus cattle.

The document titled "Stepwise approach applied to metabolites related to residual feed intake in Angus cattle" discusses the use of omics methods to identify important plasma metabolites related to feed efficiency in beef cattle. The study used a stepwise approach to select metabolites and found differences in concentrations of certain amino acids and other compounds between low- and high-feed intake animals. The authors suggest that these metabolites could potentially be used as biomarkers for feed efficiency selection. Further validation is needed to confirm their potential. The document is relevant for library patrons researching feed efficiency in beef cattle. [Extracted from the article]
