Hi we have a small operation of 12 purebred Simmentals and 20 commercial cows in Alberta. we have been doing it for about three years now on our own after a life time of cattle with my wife's dad. Anyways looking at getting into AI to Mix up the genetics. We have mostly reds but bought a black this fall. Just looking for suggestions on what everyone is using for performance bulls and to fix some ugly udders. I know you can't do it all at once thanks in advance
