All: I have been breeding our cross cows to a Santa Gertrudis bull. We kept 6 of the best heifers for replacements. My neighbor thinks we are crazy, he tried Santa's years ago and had bad luck. We breed the heifers to a Executive Order Simmental bull (my brother needed a place to put him, so we used him). We like our Santa bull, the most gentle thing anyone could have. has anybody else had bad luck with Santa's?.
