Alright, so I just spent the past little while here tallying some things up for everyone here. Listed below are all the founding bulls, their total living descendants, and their male descendants currently contributing to the NA and European populations. As you can see, there is a rather distinct divide, between bulls who are pumping out copious amounts of offspring, and bulls who are merely providing a small trickle of new genetics, or none at all (especially in North America). Animals with a "*" behind their name are currently in breeding situations where they have a realistic hope of siring offspring via natural breeding.
There would be no point in sending a Mabu offspring to Europe, as they currently have six bulls with absolutely no representation whatsoever, and they should be prioritized over an imported bull. Happily, however, the majority of their genetically valuable bulls are indeed in breeding situations, and those that aren't (sans Carl) stand a good chance of entering a breeding situation, via either AI or natural methods, within the next 2-5 years.
However, in North America, our founder representation is absolutely ABYSMAL. Two males together have sired over twice as many offspring as all the other males combined. Absolutely pathetic. There are TEN bulls who are completely unrepresented, who are wasting away at facilities where they have no realistic chance of breeding naturally.
In regards to the issue of mabu's genes, there's absolutely ZERO need to cull any of his offspring, all that's needed is to pull Mabu from major production. For the time being, I would simply put his male offspring into bachelor situations as they come of age, and that would solve the issue of all his male offspring. Birmingham could easily house 2-3 of his calves alone.
In terms of Mabu himself, as I insinuated, I actually would NOT like to see mMabu stopped from breeding. Instead I would like to see him jumping from facility to facility every few years, breeding with cows that desperately need to be bred. Asali at Memphis, Christi and Zuri at Hogle, Tonga and Batir at North Carolina, Makena and Tanya at Montgomery, Felix at Atlanta, Victoria, Angelina, Zuri, and Savannah at Pittsburgh, Moja at Wildlife Safari, these are all older cows that are in desperate need of producing a calf to ensure their continued reproductive health, or young cows at ideal ages for a first calf. While it would obviously be preferable to breed these cows with more valuable bulls, some of them have never been with a bull in their lives, and others may not accept the advances of a less experienced bull. Mabu is in an ideal place (30 years old, has successfully bred many times with 6 different cows, gentle yet assertive, good with calves, well trained, used to transfers, etc...) to keep these cows breeding and setting them up well for future interactions with other bulls, or even just "resetting their timers" to give the zoos more time to try and get them pregnant via AI.
