feed additive provided by the invention is
solid, thereby having the advantages of being convenient to store, transport and add; 3, the product provided by the invention can improve the
organism health condition, improve the
immunity of the
organism, reduce the
feed conversion ratio, and has importance to development of
animal husbandry, promotes the coming of 'antibiotic reduction, zero antibiotic'; besides, the application range of Humulus lupulus is widened, and the feed additive has important significance to healthy development of Humulus lupulus planting industry.
