The hormone that plays a significant role during the egg-laying process in poultry is oxytocin. This hormone is crucial in various reproductive functions, particularly in stimulating the contraction of the smooth muscles in the oviduct. This contraction helps move the egg through the reproductive tract to ensure the proper laying process occurs.

While other hormones, such as estrogen, are involved in the breeding cycle and overall reproductive health, oxytocin directly contributes to the act of laying eggs. Its role in facilitating the physical process makes it essential during this particular phase of reproduction. Understanding the hormonal interactions involved in poultry reproduction can help in managing breeding programs and improving the efficiency of egg production.
