Covalently bonded zinc sources have better relative bioavailability than ionic mineral sources. Minerals appear simple, but mineral nutrition is more complex than ever. | Digieye, Dreamstime adopted feeding practices demonstrates that in order to maximize health and performance under commercial conditions, mineral requirements are likely higher than those previously established in high-health animals. MYTH 2 Oxide and sulphate trace mineral sources are well-suited for today's animal nutrition Traditionally, inorganic sources like oxides or soluble mineral salts like sulphates, have dominated the inal !
