How old does a cow or heifer have to be until they have their periods?

Bovine females do not have their "periods" like human females do. The "period" is a loose or code term for when the endometrium layer is shedding and the girl or woman is experience heavy bleeding from the uterus through the vaginal opening. Cows nor heifers experience none of this. They have a sexual receptive period called Estrus where they experience high estrogen levels that drive them to search for and find a bull to breed with. Human females do not have a defined sexual receptivity period, so all their reproductive cycling is denoted by the timing of their periods.
Depending on the breed, the average age for a heifer to experience her first estrus period is between 13 and 18 months of age. See the related questions below for more information.

Can a cow get pregnant at 9 months old?
Cows aren't cows if they're only 9 months old. You would be talking about a heifer, not a cow. And yes, a heifer can quite possibly get bred at 9 months of age, especially if she had been showing heat signs before she was weaned.
How much does a 6 month old bull cow weigh?
There is no such thing as a "bull cow." Either you are talking about a bull, or a "cow" which would be a weanling heifer. As such this all depends on the breed of that animal.
How long will it be before a calf is considered a cow?
Generally, calves go through three stages, the first being the "calf" stage. Then, when they are yearlings, they are either considered a "heifer" if they are female, "bull" if they are male, or a "steer" if they are a castrated male. Once a heifer has her own calf, then she is considered a cow.
What is the cow's son called?
A "daddy cow" is known as the sire. In actuality, cows are mature female bovines, or the "mommy cow," or more properly known as the dam. Bulls are intact/mature male bovines, hence being the "daddy cow" or sire of a calf or next-generation bull, steer, cow or heifer.
What is another name for cow?
According to the Encyclopedia Britannica, all modern domestic cattle are believed to belong to the species Bos Taurus (European breeds such as Shorthorn and Jersey) or Bos indicus (zebu breeds such as Brahman) or to be crosses of these two (such as Santa Gertrudis).
Can an 18-month-old heifer feeding off a cow who has not calved in years cause problems such as digestive upset for the heifer or mastitis for the cow?
It depends on whether that cow is her mother or whether this heifer is a milk-thief. Mastitis can occur when the udder is subject to such injury as excessive bumping when the cow is running, when it's stepped on, or even by bacteria simply entering the teat canal into the udder. But if this cow hasn't calved in years (however long that is), and is still producing milk, possibly primarily for this heifer, then there's a chance that no, she won't get mastitis from the heifer nursing her. However, there is a chance that the heifer may get some form of digestive irritation if she is nursing on an infected quarter/udder. But in reality, it's a really complex question with a lot of variables, and is more than just a yes or not to both type of question to answer.A method of stopping the heifer from doing this is to put an Easy wean (can be bought at your local feed store) ring in her nose (this will not cause harm to the heifer).This will slightly poke the cow she is trying to steal from so they wont allow her to nurse.Please view the related link to learn more about what causes mastitis and how to treat.
What are the names given to a calf at different stages of life?
A calf is a calf from birth to weaning. That calf is no longer a calf after weaning, but a bull (if male and intact), a steer (if castrated) or a heifer (if a female). If the calf is being used for beef, at weaning age it's called a feeder calf. A feeder become stocker steer/heifer/bull when put out on pasture, usually when it reaches around 12 months of age. The calf is called a finisher when it goes into the feedlot to be put on a "hot" ration prior to slaughter, then a slaughter bull/heifer/steer when it is sold to be slaughtered for beef. This part of the equation is primarily reserved for steers. A heifer calf is a female calf from birth. She becomes a weaned heifer when weaned, a heifer after she's gone through the weaning process, then a bred heifer when she gets pregnant for the first time. After she has had her first calf, she is called a first-calf heifer. She can also be considered a cow at this time. She will remain a cow until she dies of natural causes or illness, or is slaughtered for beef. A bull calf is a male (intact) calf from birth. He is referred to as a weanling bull when weaned, then a young bull after being weaned and is not quite a year old. He is referred to a as a yearling bull when he reaches a year old and until he turns 2 years of age. He will then be referred to as a 2-year-old bull when he reaches two. He becomes a Mature bull when he reaches full maturity by the time he's 4 to 5 years old, and remains so until he dies of natural causes or is slaughtered for beef.
What is another word for a female heifer?
She can also be known as a heifer calf, heifer yearling (if she is a year old), or first time heifer (if she has given birth to her first calf).
What age can a heifer calf come in heat?
A cow can be bred 45 to 80 days (or a little longer) after she has calved and during her heat cycle which is once every ~17 to 24 days. Heifers can be bred by the time they reach between 9 and 18 months of age, (preferably 15 months of age or older) and/or weigh 60% of the average mature cow-herd weight, since some heifers may not be able to be bred until they're ~20 months old, like with most Brahman heifers for instance.
What is a female breeding cow called?
A cow IS female. A cow is a female mature bovine that has had a calf. However the general population tend to refer to a " cow" as a more general term for any bovine of the Bos taurus or Bos indicus species, particularly if they can't tell the sex of the animal from near or far.
What is the age limit of a bovine Heifer?
Most heifers should be around 15 to 18 months of age to be receptive and be able to get bred. Of course this depends on the breed and the type of cattle. For dairy cattle, a farmer aims to have a heifer calve by 24 months, or two years of age. The gestation period for a cow is approximately the same as for humans - nine months. Hence, a farmer usually aims to inseminate a heifer at 15 months of age, but this also depends on the health and condition of the animal and whether is is physically fit to become pregnant. For beef cattle, a heifer generally should be inseminated at around the same age. However, some breeds are quite late maturing, and will only be able to get bred at 18 to 22 months of age. Brahmans (or Zebu-type cattle) are late maturing, enough that only sees heifers getting bred or inseminated at this age.
