At termination of this study (35 d), the total amount and concentration of the minerals that were determined in this study did not differ in pigs fed the Zn supplemented diets, except for cubic response of total Cu and Cu concentration to organic Zn (P ≤ 0.05) and total Zn and Zn concentration in the liver, with a linear response (P ≤ 0.01) to organic Zn and inorganic Zn (P ≤ 0.01).
