Observations: Estimating the maximum longevity of domestic cattle is troublesome since there are many conflicting reports. Females appear to remain fertile for about 12 years, and animals have been known to live over 20 years [0434]. Most likely, animals can live over 20 years and there are even anecdotal reports of a cow called "Big Bertha" that lived nearly 49 years. Lastly, there are unverified reports that miniature cattle live longer than normal animals.
