Interpretive Summary:

Technical Abstract: Pullets must have sufficient body size and carcass stores at the time of photostimulation in order to reach sexual maturity within a proper interval and to maintain reproduction later in life. This chapter discusses the separate effects of feeding level and age of photostimulation on ovary development, and shows how plasma reproductive hormone profiles are modified by feeding level.
