For the layer feed during the egg-laying period, on the basis of many-help 324, essential amino acids, trace elements, and other uniquely developed nutrients necessary for laying hens are added. The consistent use of many-help 324BR can effectively reduce the incidence rate and mortality rate, significantly reducing the need for medication; it maintains a stable peak egg-laying period for a longer time, with minimal fluctuations in the egg-laying rate; experimental data shows that it can improve the pass rate of hatching eggs, fertility rate, hatchability, and healthy chick rate.
