Heat production of chicks with and without access to feed and water during the hatchwindow
In current practice, chicks are provided with feed and water directly post-hatch more often. When feed and water is provided directly post-hatch, heat production of day-old chicks is expected to be increased in comparison to withheld chicks. To ensure a comfortable environment (combination of air temperature, relative humidity, and air velocity) for fed chicks post-hatch, it is crucial to know how the intake of feed and water affects heat production in the perinatal period.
The aim of this trial was to investigate effect of feed and water access directly post-hatch on heat production between hatching and pulling.
