Shanawany, 1982 – The Effect of Ahemeral Light and Dark cycles on the Performance of Laying Hens – (A Review)

During the past decade research work has indicated that ahemeral cycles could markedly influence egg production, shell quality and egg weight. The major advantages of such cycles are that they can be easily applied and are reversible. This paper examines and reviews the published information in an attempt to summarize the effect of such cycles on the birds’ laying performance.
