Shoof Chinball Harness

The robust harness - halter has a cone shaped device underneath which contains a freely rotating ball, working on the same principle as a ball-pen. The stainless steel ball container can be filled with ink of the desired colour. Each 0.5-litre fill is enough to mark 25-30 cows. When a cow is properly in season she will receive very clearly identifiable back markings from the bull wearing the device. Marks fade in 4 to 14 days.
