Embryonic mortality and hatchability were not affected (p &gt; 0.05). By day 42, broilers incubated under green LED light exhibited lower body weight and cumulative weight gain (p &lt; 0.05), though feed conversion ratios remained similar across groups (p &gt; 0.05). Carcass analysis revealed no significant differences in yield, but relative liver weight was higher in the green LED group (p &lt; 0.01).
