Commercial poultry production is associated with various types of stress leading to decrease
of productive and reproductive performance and compromised health of growing chickens …

The decline in eggshell quality resulting from aging hens poses a threat to the financial
benefits of the egg industry. The deterioration of eggshell quality with age can be attributed …

Thermal stress has been shown to result in decreased egg production, decreased eggshell
quality, and ultimately millions of dollars in losses to the industry. Therefore, there are many …
