Cows in the wild have longer life expectancies. Most can live up to 15 to 20 years. Story greatly surpasses expectation, but there was once a chance that she too almost faced the worst.
Bison mate in August and September; gestation is 285 days. A single reddish-brown calf nurses until the next calf is born. If the cow is not pregnant, a calf will nurse for 18 months. Cows nurse their calves for at least 7 or 8 months, but most calves seem to be weaned before the end of their first year. [70]

Cows produce calves annually as long as their nutrition is sufficient, but not after years when weight gain is low. Reproduction is dependent on a cow's mass and age. [52] Heavier cows produce heavier calves (weighed in the fall at weaning), and weights of calves are lower for older cows (after age 8). [52]
Most wild bovids live for 10 to 15 years. Larger species tend to live longer; [3] for instance, American bison can live up to 25 years and gaur up to 30 years. The mean lifespan of domesticated individuals is nearly ten years. For example, domesticated goats have an average lifespan of 12 years.
Cattle have played a key role in human history, having been domesticated since at least the early neolithic age. Archaeozoological and genetic data indicate that cattle were first domesticated from wild aurochs (Bos primigenius) approximately 10,500 years ago.
Cows have an average gestation period of about 283 days, but that number can change based on the breed of the cow and the sex of the calf. Even age can change how long a cow mama is pregnant.
Males disperse more often than females, as adult cows are more tolerant of female offspring from previous years. [41] Elk live 20 years or more in captivity but average 10 to 13 years in the wild. In some subspecies that suffer less predation, they may live an average of 15 years in the wild. [42]
