Nutrient Digestibility, Performance and Egg Quality in Laying Hens
An environmental temperature varies from –5 to +5°C in many regions of the world during winter
months. Such cold conditions cause some adverse effects including increased feed intake, decreased egg
production, egg quality, nutrient digestibility, and feed efficiency in laying hens. In the present study, the effects
of vitamin C and chromium supplementation on egg production, egg quality in terms of egg weight, specific
gravity, egg shell thickness, egg shell weight and Haugh unit and digestibility of nutrients in laying hens reared
under a low ambient temperature (6.2°C) were investigated.
