Challis is used primarily as a heifer bull for Excelsus and responded in the most unbelievable way, seizing the opportunity with both hands, or hooves. He was a surprising top three breeder for Excelsus, standing well with Mcix and Langman, when an analysis of the calves from our breeding bulls was done. Another pleasant surprise is his calves weaning indexes topping the pile with a Challis son, Canut weighing in at 309kg with a corrected mass of 295 kg out of a first calving heifer, Wexi. A son of our Junior Champ, Chris, who is also a birth mass trait leader and out of a Metsibra UDM9453B daughter, Tac. Producing heavy weaners of a good type, use Challis on Brahman type females.
