You mean the time between when a cow gives birth and when she's is to be rebred, right? If that's the case, then the optimum time is between 45 to 60 days, though to make sure a cow breeds the same time as she did previously, it's best to have her bred between 80 and 90 days after she has given birth.
If you are asking about the time between when a calf is born and when that calf is ready to breed, that depends on its gender. A heifer calf will typically be ready to be bred when she's around 15 to 18 months old, though some producers can get away with breeding them at a younger age with no issues. A bull calf will be ready to breed by the time he's around 12 to 14 months old, though he too can be ready to lose his virginity at a younger age.
If you are asking about something completely different from what I went over above, then it would probably be around 2 years to see if a bovine is fertile or not. With a heifer, that would be when she calves or if she is able to settle after being bred. It also would be when she is able to come back into heat fairly quickly after giving birth. If she cannot come back into heat under a minimum of 80 to 90 days after parturition, then she is deemed to have low fertility. With bulls, that would be when they are yearlings upon which they are ready to be used as breeders. Their fertility rates will come up when they get semen tested before they are set to breed heifers or cows, or show up when the cows and heifers that they have been set to breed are preg-tested.
Fertility, though hereditary, has more to do with the body condition score and the nutritional level of an animal. If a cow or heifer has poor body condition and/or improper nutrition, they will have low fertility. If they have normal to good body condition (or even a little over-conditioned, especially for beef cows, not more to dairy cows) and are on a good nutritional program (good quality feed, loose minerals, good pasture, etc.) then they will be highly fertile.

What is fertility awareness?
Fertility awareness-based methods are a form of natural family planning. These methods require you to keep track of your menstrual cycle to determine the days that you can get pregnant. Fertility awareness-based methods are inexpensive. They are also hormone-free. These methods can be used for birth control. They are also a good way to know your body better. You will notice changes and better understand your menstrual cycle. Types of fertility awareness are: Standard Days (SDM): you can use this method if your menstrual cycle is between 26 and 32 days long. You will need to record your periods and determine when you cannot get pregnant. TwoDay (TDM): for this method you need to observe cervical discharge to see when you are fertile. Cervical Mucus: your body makes a specific goo when you are most fertile. This method is about tracking your cervical mucus.
