Prevotella copri, a potential indicator for high feed efficiency in western steers.

Anim Sci J 2019 Mar 7. Epub 2019 Mar 7.

Department of Animal Science, University of California, Davis, CA, USA.

There has been a great interest to identify a microbial marker that can be used to predict feed efficiency of beef cattle. Such a marker, specifically one that would allow an early identification of animals with high feed efficiency for future breeding efforts, would facilitate increasing the profitability of cattle operations and simultaneously render them more sustainable by reducing their methane footprint. The work presented here suggests that Prevotella copri might be an ideal microbial marker for identifying beef cattle with high feed efficiency early in their life span and in the production cycle.

Effect of different time intervals after feeding on plasma metabolites in growing pigs: an UPLC-MS-based metabolomics study.

Anim Sci J 2019 Apr 3;90(4):554-562. Epub 2019 Feb 3.

State Key Laboratory of Animal Nutrition, China Agricultural University, Beijing, China.

A diet consumed by pigs provides the nutrients for the production of a large number of metabolites that, after first-pass metabolism in the liver, circulate systemically where they may exert diverse physiologic influences on pigs. So far, little is known of how feeding elicits changes in metabolic profiles for growing pigs. This study investigated differences in plasma metabolites in growing pigs at several intervals after feeding using the technique of metabolomics. Read More
