Chicago P is still one of the highest polled sires in the country according to RZEuro. He combines very good profitability with excellent fitness and health values, a functional exterior and a very long useful life. A particular strength, however, is that he is an absolute outcross sire for polled breeding. Not only can he be used on all offspring of the P sires that have recently been used a lot in Germany, such as Simon P, Solitair P, Hotspot P or their sons, but also on offspring of the previous generation of influential P sires such as Mission P, Powerball P or Apoll P. Chicago is also testing A2A2, is very good for heifer insemination (KV mat. is also good with 108) and with a RZRobot of 104 also suitable for AMS farms.
