Afrikaners have good fertility, and can continue to calve over the age of 16 years,[1] with records showing cows calving at 21.[2] The cows are very maternal, and one female will often care for a number of calves while their mothers graze elsewhere.[2] They have few calving problems, due to the structure of their hindquarters and small calf sizes (30–35 kg).[3] They have a low calf mortality rate.[2]
