We also demonstrate that particle size and/or molecular weight of oat β-Glucans and exposure of specific binding sites for the receptors might be important tools for designing efficacious functional feed and food additives.
Some functional feed additives, such as prebiotics (Rastall and Gibson 2015), probiotics (Gao et al. 2017), phytase (Borda-Molina et al. 2016), and fermented Ginkgo leaves (Zhang et al. 2015), are reported to maintain microbial populations and support the health of the host.
By using transgenic microalgae -- a natural ingredient of fish diets -- Porphy and Lamb believe they have created a platform for cost effective vaccine manufacturing, and a vehicle for oral administration of vaccines and functional feed additives.
MSX's oral vaccines and functional feed additives, on the other hand, have the potential to replace hand-held injections with vaccine doses integrated into the fish's regular diet and making the process more cost effective and sustainable.
Thus, the effects of dietary functional feed additives and their interactions need to be assessed to develop economically viable feeds and feeding practices to optimize growth, improve stress resistance, immune response, and disease resistance and improve product quality of aquaculture species.
