There are many reasons for the production of white shell eggs, mainly due to the following reasons:
1. Pathological white eggshell. E. coli disease, egg drop syndrome, pasteurellosis, infectious bronchitis, etc. will make the eggshell color fade pale.
2. Aging white eggshell. Ageing can also cause chickens to reduce egg production and eggshell whitening. Increasing nutritional drugs can improve this phenomenon to a certain extent, but it will not last long and should be eliminated in time according to market conditions.
3. Nutritional white egg shells. In the chicken feed, vitamins and minerals, especially calcium and phosphorus deficiency, can occur in white egg shells, the most common of which is in the early stages of hen production. Addition of vitamins A, D, E, C and amino acids in the feed significantly improves eggshell color.
4. Stress white shell. Transmigration, epidemic prevention, and external disturbances all cause stress reactions in chickens, resulting in decreased egg production and lighter eggshell color. This kind of change lasts for a short period of time. When measures are taken to improve the environment, supplement drinking water, and other measures, the white egg shell phenomenon will soon disappear.
5. Light white shell. The light during the laying period should be constant. Insufficient light or instability and irregularity can cause chickens to produce white shell eggs. Artificial fill light should be stable, coupled with scientific feed nutrition, can guarantee excellent eggshell color and longer egg production peak period. Http://
