For a start, the majority of stags born never sire any offspring, whereas most hinds will produce a calf every year throughout their productive life. And the productive herd life of a stag is relatively short. His female contemporaries will still be breeding long after he's been culled or ousted by another male.I’ll go out on a
How so? I'd have thought 1 stag will pass his genes onto maybe 20 hinds so a bit of genetic diversity on the female side but little on the male side. I know deer parks often introduce new stags / bucks to bring in some new blood but I've not heard of it happening much with hinds / does unless they were looking to increase herd size.
That's a genuine question btw - I know you have a lot of experience of this with your own deer etc.
And it only takes one bullet to remove a stag. Trying to change your female stock is a different proposition altogether.
Introducing a new stag to a herd obviously brings in new genetics, but the effect may be short-lived. And, if you're running more than one stag then you'll never actually know which one is the sire of the calves.
And if you do introduce a new male, and he's a success, then it'll most likely be through his daughters that the lineage continues, not through his sons. So management of the hinds is the most important thing if you want to disperse his genetics through the herd.
Adding new females to a herd is a far more reliable and long lasting way to introgress new genetics, but most people are so obsessed with the males that they don't appreciate this. It's the same with all livestock breeding.
