RTOP Mr Heinrich 513U (and RTOP Mr Feagin 522U) are full sibs out of our tremendous Donor cow, Great Guns Gusti 8M. Although Gusti died early, she had a profound impact on our herd. Each of these bulls brings his own strength to the table. Heinrich is a more refined bull with lots of flash while Feagin (AKA Doc) is a power bull with lots of muscle expression. Either of these bulls will add growth and pizzazz to their progeny.
