Impact of light intensity or choice of intensity on broiler performance and behavior

open access: yesJournal of Applied Poultry Research, 2022
SUMMARY: The optimal light intensities for broiler production and well-being have been investigated for some time. The use of a minimum 20 lux (lx) is mandated within the European Union (European Commission, 2000; European Union 2007).
