What is the role of Thyrotropin in poultry?

Stimulates ovulation
Regulates activity of the thyroid gland
Promotes egg laying
Parathyroid function

The correct answer is: Regulates activity of the thyroid gland

Thyrotropin, also known as thyroid-stimulating hormone (TSH), primarily functions to regulate the activity of the thyroid gland. In poultry, this hormone plays a crucial role in stimulating the thyroid to produce and release thyroid hormones, which are essential for regulating metabolism, growth, development, and overall energy levels in the birds. These thyroid hormones heavily influence various physiological processes, including how the bird responds to dietary influences and environmental changes. The regulation of the thyroid gland by thyrotropin is vital because imbalances can lead to metabolic disorders or developmental issues in poultry. While this hormone is not directly responsible for stimulating ovulation or promoting egg laying, it indirectly affects reproductive health through the influence of thyroid hormones on overall health and vitality. Thus, options related to ovarian function or parathyroid activity do not accurately describe the primary function of thyrotropin.
