Using your argument you are then trying to convince people that because we have fewer adult does those does that are left will have a lower breeding and reproductive rate, per individual doe, then the does had when we had more does.
That is not what I said. What I said was that because the average age of the adult doe herd has been reduced significantly by removing more 2.5+ doe, there is a higher percentage of 1.5 doe in the herd and 1.5 doe on average will have lower breeding rates and fewer embryos/doe.
