Integrative Transcriptomic and Genomic Analysis Reveals the Regulatory Mechanisms Underlying Semen Quality Stability in Ganders.

ABSTRACT: Semen quality significantly affects the reproductive performance of ganders. As seasonal breeders, ganders typically experience a decline in semen quality over the breeding season; however, the mechanisms regulating semen quality stability during this period remain poorly understood. Maintaining high semen quality throughout the entire breeding season is crucial for improving production efficiency. In this study, we systematically investigated the semen quality parameters of Tianfu Meat Goose II ganders at three distinct stages of the female geese's annual laying cycle: early (36-week-old), peak (47-week-old), and late (66-week-old) laying stages. The results showed that the ganders in stable (S) semen quality group exhibited superior semen quality parameters compared to those in unstable
