Ulf Tubessing, 22 Jyly 2022: Hi everybody, any suggestions re this "nyala bull" coat? I have no further history re origin etc. Bossie Boshoff, [22 Jul 2022 at 15:39:15]: Red bull? Normally the testis are super small on all the ones I have darted (4). Douw Grobler, [22 Jul 2022 at 15:39:47]: We see this regularly....no testis or super small testis Henry Labuschagne, [22 Jul 2022 at 15:42:06]: As mentioned above the have small testes and are not fertile. He is tagged so he must have been handled before. Any history on testes exam ? Henry Labuschagne, [22 Jul 2022 at 16:18:59]: The dewlap on that animal is also smooth. Check if it is not a female. Johan posted photos of a waterbuck cow with impressive horns some time ago. Even in young bulls the dewlap has long hair. Douw Grobler, [22 Jul 2022 at 16:22:32]: The nyala females with horns are normally not as symmetrical as that one in Ulf's video. They tend to be skewer and not as well developed Henry Labuschagne, [22 Jul 2022 at 16:25:10]: Agree Douw. The red bulls that I have darted (3) all had long hair on dewlaps. Your experience ? Henry Labuschagne, [22 Jul 2022 at 16:29:22]: Bossie. Your observation in red nyala bulls ? On the web there are photo's of red bulls with smooth necks .
