Abstract: Provided is a method of using a copper-calcium sulphate as an animal feed additive. When used in animal breeding, a low dose of the copper-calcium sulphate can achieve the effect of that high dosage of copper sulphate achieve in the promotion of animal growth, and thus the copper-calcium sulphate can be used as an animal basic nutritional supplement to substitute low-copper preparations in the breeding of poultry, livestock or aquatic animals.
