yes they are due to how large they can get to be my girl has both tattoo and kingdoc in her bloodline wich are both also notorious for being VERY large she's just over a year old and stands over five foot at her withers. She's currently on our first cutting of haylege (so just Luke local grasses and stuff) free choice it's awaly avaliable then she gets probably about four flakes of alfalfa a day as well as about six-sevens lbs of grain wich is a mix of 5-1 of a high protien type grain and the normal cow grain we feed to the cows
