What hormone stimulates the laying of eggs in poultry?

Thyroid Hormone
Follicle Stimulating Hormone
Luteinizing Hormone
Estrogen

The correct answer is: Estrogen

Estrogen plays a crucial role in the reproductive cycle of poultry, particularly in the stimulation of egg laying. This hormone is primarily produced in the ovaries and is essential for the development and maturation of the follicles in the hen's ovary. As the follicles mature, estrogen levels rise, leading to the development of the egg and triggering the laying process. In addition to stimulating the physical aspects of egg formation, estrogen influences behavioral changes in hens, which can encourage mating activity and promote reproductive success. Therefore, its essential role in the physiological process of egg production distinguishes it as the primary hormone associated with stimulating egg laying in poultry. Understanding these hormonal influences is vital for poultry management and breeding practices.
