In global Holstein breeding the aAa code sequence 156 is showing a tendency to become unique rather than standard. Many new bulls in recent years have aAa code 234 or another combination of these three numbers. K.I. SAMEN offers a wide range of aAa code combinations, which represent more width and balance.

K.I. SAMEN has offered an extensive range of bulls with round traits for years. Which bulls have performed exceedingly well over the past decades and offer round traits or a more unusual and unique aAa code? And which younger generations of bulls offer something out of the ordinary? Bulls such as Abel, Cosmo, Rembrandt, Maik and his sons, Murphy, Floyd and Boomerang are just a few names who, in our 40-year history, had or have something unique to offer breeders.
