Inbreeding coefficient example
WebAs an example, consider a herd with a feedlot average . daily gain (ADG) of 2.25 pounds per day. Assume . further that a sire from this herd had a 3.50 pounds per day feedlot ADG, while a younger half brother has not, as yet, been evaluated for feedlot ADG. Assuming no inbreeding, the coefficient of relationship between half brothers is 0.25.
