Graphical Abstract
Metagenomics and metabolomics offer the potential to solve many problems encountered in animal production. Examination of the microbial communities present in the gastrointestinal tract can provide insight into nutrient digestibility, feed efficiency and fermentation kinetics in production livestock (Abbas et al., 2020; Li et al., 2020; Jiang et al., 2021), horses (Sorensen et al., 2020) and companion animals (Do et al., 2021). With an increasing eye toward sustainability and reduced environmental impacts, the technology can be applied to the study of methane emissions and antimicrobial resistance (Ross et al., 2020; Rothrock et al., 2021). Asselstine et al. (2021) provide a comprehensive review of the emerging technologies as they relate to rumen fermentation and methane emissions.
