Long-day photoperiods affect expression of OPN5 and the TSH-DIO2/DIO3 pathway in Magang goose ganders.

ABSTRACT: This study sought to understand the regulation mechanism of OPN5 through the TSH-DIO2/DIO3 pathway mediated photoperiod on the breeding activity of short-day breeding birds. In this study, the reproductive activity of Magang goose was regulated by artificial light, and the reproductive activity of the ganders were determined according to the daily laying rate of female geese. The testicular development and the serum reproductive hormone concentrations of ganders were measured during the reproductive period (d 0), the reproductive degeneration period (d 13 and 27) and the resting period (d 45). The mRNA and protein expression patterns of OPN5, the HPG axis reproductive genes, and TSH-DIO2/DIO3 pathway related genes were examined. Results showed that the laying rate of geese and the gonadal
