Negative three to four months, assuming the cow gets bred two months after calving and the calf is weaned at six months of age. Seriously, a cow is already bred and into her second trimester when her calf is weaned. Cows are not like human females where they can only get pregnant again at least a year or 8 to 12 months post-partum.
After 12 months
The average weaning time would be 8-10 months. The mother will naturally wean the calf around 12 months.
Cows have already been weaned, so you would be referring to a calf, not a cow. The weaning age of a calf is 3 to 4 months when on the bottle, or 6 to 10 when on the cow.
Around 3 to 4 months of age.
A calf needs milk until he's 3 months of age, but most producers like to have them on the cow for another three to five months before weaning them.
A young bovine needs to be YOUNG, i.e., 0 days (birth) to 6 or 10 months of age (weaning) to "qualify" as a calf.
A cow is pregnant, or 'in calf', for approximatly 40 weeks (9 months).
Beef calves are the most dependent on their mothers from birth to when they reach 3 months of age. They can be kept on with their mothers for another 3 to 7 months to help in getting higher weaning weights at weaning time. Early weaning (minimum is 3 months) is only used when the cow is losing condition from nursing her calf, or if there is drought. If cows are in good condition and forage is plentiful, they will stay on for 6 to 10 months. In dairy cows though, the calves are pulled off a day or two after they're born, then raised on the bottle. A cow will let her calf nurse for up to two years if she doesn't get pregnant within that time.
65 lbs
Probably, if the calf doesn't pull the cow down before then.
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.
Yes. In a cow-calf operation, cows always have to get bred 2 months after they've calved, which means that they are still suckling a calf when they get bred and subsequently get pregnant.
First stage is when she's a calf. She subsists on her mother's milk for 6 to 10 months before weaning. For bottle calves, they are on the bottle or bucket for around 3 months. Second stage is when she is deemed a heifer, after she has been weaned from her milk source and is able to eat forages on her own. This is her growth period that allows her to reach puberty and the adequate body weight for her to be bred. During this stage she is bred at 15 months, then has her calf at 24 months. While still caring for her calf, she is still growing. Stage three is when she officially becomes a cow after weaning her first calf and her growth comes to a stop when she is deemed mature. Cows often live on average for about 10 years, some twice as long; dairy cows twice as short before being culled out of the herd to be slaughtered for meat.
