LGALS13 and avian influenza: Wang et al. (2023d) added Gal-13 to chicken feed, and the results showed that Gal-13 can improve intestinal digestion, antioxidant capacity and immune function, and ultimately promote the growth of broilers. AMPs can also be used against avian influenza in livestock and poultry. For example, in a recent study, Zhang et al. (2024a) found that cecropin AD was effective against H9N2 avian influenza virus (AIV) in chickens.
