The effect of lighting color on hatching broiler eggs during different storage periods

This study evaluated the effects of storage periods (5 and 14 days) and lighting color (white, green, red, and a mix of red and green color) on incubation and some hatching characters. 240 fertile eggs from the Rose 308 broiler breed were purchased and divided into two storage groups of five and fourteen days, each of them divided into five treatments according to the lighting color during incubation. The results showed that the eggs stored for 5 days had the maximum hatching characteristics, but they decreased significantly at 14 days. The percentage of loss in egg weight, shell weight, and relative embryo weight were affected at 5, 7 and 18 days of incubation. There was a significant effect (P 0.05) of storage on the remaining yolk sac after hatching, the weight of the hatched chick, the hatching ratio and the hatching time. The results also indicated that there was an improvement in the use of colored lighting during the incubator on the hatching qualities of eggs stored for broilers for a period of more than 5 days.
