We have been using Topp Hereford bulls for more than 10 years. We started buying them when they just were starting out. Our replacement heifers and cows that are sired by them are pretty low maintenance. Their udders are awesome and the calves that they raise are awesome. They also have great moderate frame size. I even think we have some cows sire by Topp bulls that are about 13 years old and are still going strong. We have had great experiences with them and I would recommend them to any one looking for good quality genetics.
