When they're too old to continue to give birth and suckle a calf. Some cows will keep on breeding when they're in their twenties; others will have to be culled by the time they are only 5 years old.
Cows can be bred at any age (since they are mature female bovines that have had at least 2 calves) so long as they are not already pregnant. Bulls, on the other hand, can begin to be used for breed by the time they are around 12 months of age.
Friesians can continue breeding up to their late teens, but fertility may decline with age. It's best to consult with a veterinarian or equine reproductive specialist to determine the most suitable breeding age for individual Friesian horses based on their health and reproductive condition.
Often a bull should stop breeding either if he's too old and not fertile enough any more to be used, or if he's become too aggressive and dominant with his handlers to be considered a keeper anymore. There really is no defined age when a bull should stop breeding.

Size doesn't matter in this scenario. A bull will reach is terminal (or mature) weight by the time he reaches 3 to 4 years of age, and can continue to be used for breeding, as long as he's got good fertility and libido, and doesn't challenge the owner in any way, for up to 15 years of age.

Cows used for breeding only, or cows that are already pregnant.
You should stop breeding a dachshund when they are at the oldest four years of age. If you breed them when they are older than 4 your dog may die from diseases. Hope this help!
It depends on the breed and weight of the heifer, but I have seen Holsteins as young as 6 months in heat. However, this is not a recommended age to begin breeding.
If raised for beef, they only live up to 18 to 24 months of age. If they are used for breeding, they can live for as long as 4 to over 20 years of age.
