1 In the UK, the average working lifespan of a dairy cow is around four lactations (milk-producing periods), and hence many dairy cows are culled when they are relatively young.
Most cows are productive until they are 12-15 years old. With proper nutrition and care, cows can have calves as old as 20 years of age! I know an 11 year old cow who is due to deliver this year. I would be surprised if cows are much different than horses.
