翻译中文 Like other physiological processes reproduction is highly integrated and tightly regulated by a neuroendocrine axis the hypothalamo-pituitary-gonadal axis This axis involves sensory detection of

pituitary gland. This results in decreased production of gonadal steroids and decreased reproductive activity. During the photophase (daytime), light stimulates the release of GnRH-I which then stimulates the pituitary gland to release gonadotropins (FSH and LH) which in turn stimulate the gonads to produce gonadal steroids and initiate reproductive activity. This axis is also influenced by other environmental and physiological factors such as temperature, nutrition, stress, age, and disease. Understanding the regulation of this axis is important for optimizing reproduction in poultry production
