The horns do not begin to grow until the bull is between the age of 6–12 months, twisting once at around 2 years of age, and not reaching the full two and a half twists until they are 6 years old; occasionally they may even have 3 full turns.
Os cornos non empezan a medrar ata que o macho ten de 6 a 12 meses, retórcense unha vez contra os 2 anos de idade, e non completan os seus 2 xiros e medio ata os 6 anos; ocasionalmente poden ter 3 xiros.
