I have a cow that is 50% hereford and 50% holstein with that exact color pattern... Sadly, after spending the summer with my dad's holstein dry cows eating their fancy feed, she is probably bigger than that bull... She is MASSIVE! Roughly 2200 (+/-100) pounds, looks like a plate of gelatin when she runs to the barn for her corn silage... Only has 1 working teat, but still managed to wean off a 450 pound shorthorn X (breeder used a showy shorthorn, not a good commercial shorthorn) bull calf (born October 20th and weaned/weighed February 15th) without creep feed, with good 4th cutting hay, through a typical MN winter last year... Decided to hold her over for breeding so she could have an April calf and see what she does with grass to eat. Only took 1 breeding too... If I could take off 600 pounds from her then i would love to have a herd of cows just like her. The bull calf didn't even take a beating from his shorthorn influence at the sales barn, and managed to pay for all the hay I fed at that location (the baldy cow/calf pair and another hereford X holstein X something that can transfer brindle mamma raising a red angus calf and an adopted holstein X charolais heifer calf were all I had there) for the entire year.
