We are considering buying a few older red Gelbvieh cows from a breeder that we deal with. These are cows with a few more calves left (we hope ) in them. He is going to A.I. them with any semen we want to use(of coarse we purchase)after they calve in the spring. My question is what are some of the Red Angus sires that we Should research that would be considered to have maternal traits with moderate size offspring.
