plant-based-feeds
Plant-based feeds refer to nutritional inputs derived from plant biomass, including leaves, seeds, legumes, and agricultural byproducts, used to sustain animals, aquaculture, or microbial systems. Understanding the biochemical composition of these plant-derived materials—such as protein profiles, fatty acid content, anti-nutritional factors, and digestibility—is central to plant science research aimed at optimizing crops for functional nutritional value. Advances in plant breeding, metabolomics, and genetic engineering are enabling researchers to develop crop varieties specifically tailored for higher-quality, more sustainable feed applications.

A new review examines how oils extracted from medicinal and aromatic herbs — think oregano, thyme, and their relatives — can be added to farmed fish feed to promote growth, strengthen immunity, and reduce disease. Results are promising but inconsistent across fish species and oil types, pointing to a need for standardized research before these plant oils become routine commercial additives.
Plant oils rich in phenolic monoterpenes and phenylpropenes (compounds found in herbs like thyme and oregano) can stimulate appetite and positively reshape the gut microbiome of farmed fish.
MAPOs enhance fish antioxidant defenses through the Nrf2-Keap1 molecular pathway, a mechanism also central to stress resilience in plants and mammals, leading to measurable improvements in disease resistance.
Outcomes are highly inconsistent across studies due to chemotypic variability in essential oils, unstandardized extraction methods, and dose-dependent effects that can sometimes be neutral or suppressive rather than beneficial.
