Question: 1 / 515

What role does Luteinizing Hormone serve in poultry reproduction?

Causes egg production

Triggers ovulation

Luteinizing Hormone (LH) plays a crucial role in the reproductive process of poultry, particularly in the regulation of ovulation. In female birds, the release of LH signals the ovarian follicles to mature and subsequently triggers the release of the mature ovum (egg) from the ovary. This process is essential for egg production, as ovulation is necessary for the formation of eggs.

While it’s true that LH is involved in the overall reproductive process, its primary function is to initiate ovulation rather than directly causing the production of eggs or stimulating follicle growth. Other hormones, such as Follicle-Stimulating Hormone (FSH), are more directly involved in the growth of the follicles that contain the eggs. Therefore, the assertion that LH triggers ovulation accurately reflects its primary role in the reproductive cycle of poultry.
