Bull Description

Rockstone storms into the European Genomic rankings for his official release as one of the first sons available by Rockstar (Bayonet x Moonboy). Rockstone is from a maternal line of high Index Dams founded by the Bomaz prefix in Wisconsin USA, this family farm produces milk for a local cheese Dairy and have a well-established prefix recognised by all AI Companies across the Globe.

Rockstone is another great bull to emerge from Bomaz, his different sire stack give breeders and fresh alternative to common bloodlines like Silver, Supershot, Balisto and Shottle. Breeders can expect Rockstone’s daughters to be of average stature, with plenty of strength and width through the chest and rump, they should also have exceptional production, in particular, Fat % making him the perfect choice for farms supplying cheese contracts.
