Article Synopsis
- Roan antelope populations in southern Africa are declining, prompting intensive breeding programs, but there's limited knowledge about their welfare and stress indicators.
- A study aimed to establish a non-invasive way to measure stress through fecal glucocorticoid metabolite (fGCM) concentrations, especially during reproductive activities in males and females.
- Results showed a significant increase in fGCM levels during reproductive periods for males and throughout pregnancy for females, as well as a relationship between fGCM levels and ecological factors like rainfall and temperature.
Understanding the reproductive biology of the roan antelope (Hippotragus equinus) (É. Geoffroy Saint-Hilaire, 1803) is crucial to optimise breeding success in captive breeding programmes of this threatened species. In this study, the pattern of faecal androgen metabolite (fAM) production related to reproductive events (calving or birthing, mating, gestation, and lactation), sexual behaviours as well as environmental cues were studied in captive adult male roan antelope.

The causes of the problem are poorly understood. Variation in cycle length and long periods of acyclicity are characteristics of the majority of these non-reproducing females in captivity but it is unknown whether these characteristics are a feature of reproductively successful free-ranging females.
