Natural mating ability is associated with gut microbiota composition and function in captive male giant pandas

Zheng Yan,
Yinghu Lei,
Pengpeng Zhao
et al.

Abstract: The issue of poor sexual performance of some male giant pandas seriously impairs the growth and the genetic diversity of the captive population, yet there is still no clear understanding of the cause of the loss of this ability and its underlying mechanism. In this study, we analyzed the gut microbiota and its function in 72 fecal samples obtained from 20 captive male giant pandas, with an equal allocation between individuals capable and incapable of natural mating. Additionally, we investigated fecal hormone … Show more

“…Therefore, the fibre content in bamboo food may influence the metabolism of androgens in giant pandas. Particularly in captive conditions, where giant pandas exhibit poor natural breeding abilities ( Yan et al. , 2024a ), affecting their genetic diversity, further exploration of the influence of bamboo food fibre composition on sex hormone secretion in giant pandas is crucial for addressing the challenges of their reproduction in captivity.…”
