It is necessary to ensure the content of protein in egg production in summer.

When raising layers in summer, when considering the demand for calcium, the content of protein in rations should also be taken into account. Because the amino acid produced during protein hydrolysis reacts with calcium to form soluble calcium salt, which increases the absorption of calcium by laying hens. In general, the content of protein in the diet of laying hens is 17%, which increases the amount of plant protein and reduces the amount of animal protein in the high temperature season.
