Zinc (Zn) is involved in many catalytic, co-catalytic, structural, and regulatory metabolic processes in animals. Its deficiency in dairy cattle leads to many disorders Dairy animals Exogenous supplementation of Zinc, at least 60 mg per kg of dry matter is necessary for dairy cows (National Research Council, 2021). Among the different sources tested, organic sources are better bioavailable than inorganic sources. Besides bioavailability, the effectiveness of organic Zn sources is significantly visualized than inorganic sources in various metabolic processes.tested, with respect to all the aspects tested viz. bioavailability, retention, production, and performance efficiency in dairy cattle. The results of the present study confirm that ZnP supplementation showed a superior effect than any other Zn sources
