Five zinc sources compared in broiler diets
Two inorganic (zinc sulfate, zinc oxide) and three organic (zinc acetate, zinc-methionine, zinc-lysine) sources were tested at 40, 80 and 120 mg/kg from day 1 to 42. Organic sources increased feed intake and weight gain compared with inorganic ones and improved feed conversion after the first week.
Practical takeawayOrganic zinc compounds benefit broiler performance and can allow lower zinc levels in the ration.
