Funny you should mention this....because I was surprised at what was written, too. I read it to learn about dispersal. They are saying that if all of a buck's needs are met where he is reared.....he won't disperse. This goes against everyhting I've ever heard. That's a reason I thought it was interesting. There was another question regarding "inbreeding", also. They say that it will NOT adversely affect the herd as much as one would think.....because of the fact that does are generally bred by multiple mates. In the event of twins.....2 sires is common. Triplets and three sires is also the norm. Take into account "some" dispersal.....some die-off....and a bloodline quickly becomes diluted.
