The invention mainly relates to the technical field of breeding, and discloses a method capable of improving egg yield of egg chickens. The method comprises the steps of reducing the density, controlling the
nutrition, sterilizing for resistance to diseases and adjusting the environment; the method is simple, so that the egg yield is increased by 13.4%, the feed-egg ratio is reduced, the shell
cracking rate of eggs is reduced to 0.8%, and the
economic income of a farmer is increased by 10.7%; the breeding density of egg chickens is reduced, the
motion range of the egg chickens is increased, the egg fragrance is aromatic, the content of
cholesterol is reduced by 10.3%, heart and
cerebral vessel health can be protected, and a hypertension patient can also eat the egg; before egg-laying maturity, fermented egg-shell
meal is added into feed, so that egg shells are changed into wealth from waste, the feed after
fermentation is beneficial to
digestion and adsorption, a
calcium element in the body is increased, forming of egg shells is promoted, the egg yield is increased, and the egg
cracking rate is reduced;
potable water is replaced every day, the
digestion and the adsorption are promoted, other ingredients can provided rich
vitamin and mineral elements, can also
resist bacteria and inhibit
bacteria, strengthen the
disease-resistant ability, reduced the occurrence of diseases, and improve the egg yield.
