O'KALIBUR RF is a top-class conformation sire. His granddam is the sensational double HI World Champion (2013 & 2015) and multiple show winner Decrausaz Iron O'Kalibra EX-97. The now constantly calving daughters of O'KALIBUR RF show the expected excellent conformation; they impress with deep, open ribs, very wide, well-sloped rumps, a little more angle in the hind legs with a parallel position and grandiose, high and wide attached udders, which effortlessly produce up to a good 40 kg of milk. He tests beta-casein A2/A2.
