Molecular mechanisms underlying the testicular developmental variations among different lines of Tianfu Nonghua duck.

ABSTRACT: The reproductive and economic performance of male poultry depends on the testicular development and semen quality. However, most previous studies on male duck reproduction have focused on environmental impacts or developmental dynamics within a single breed, so the mechanisms of duck testicular development remain poorly understood. In this study, by taking a total of 240 males from 3 different lines (GF₁, BGF₂, and MC) of Tianfu Nonghua duck during the first 24 post-hatch weeks as the experimental objects, we comprehensively analyzed the age-dependent variations in the testicular histomorphological characteristics, serum testosterone (T) contents, and hypothalamic-pituitary-testicular (HPT) axis-related genes expression profiles, aiming to unravel the molecular mechan
