A heavily pregnant cow, or a long-bred cow. Or, a cow that is expecting soon.
NO
Cows never get pregnett the get pregnant. They are pregnant for 9 months
A cow is pregnant, or 'in calf', for approximatly 40 weeks (9 months).
Probably, if the calf doesn't pull the cow down before then.
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.
No, preg cows shouldn't be jumping each other, but they can if there's an open cow in the herd that's in heat. Mucus discharge is another sign that a cow is either in heat, or is ready to give birth within 24 hours.
No. A pregnant cow can still lactate or give milk. A bred cow will have a "wet" (lactating) period and a "dry" (non-lactating) period. A cow's "wet" period lasts from parturition until her calf is weaned or, if she's a dairy cow, the farmer decides to let her dry off and rest before she calves again. A cow's dry period lasts from the time she is dried off (dairy farmer's decision) or when she has a calf weaned off her (beef cattle) until next parturition. After a cow gives birth, she has 45 to 60 days (or around two-months, sometimes up to 3 months) of rest to allow her uterus to involute or go back to normal size, and allow her to go back into normal estrus cycling. After this period she is bred again, either by bull or artificial insemination. She will still be producing milk even after she has settled and become pregnant again. A beef cow will be lactating until her calf is around 6 months old. Once her calf is at this age he is weaned from her, and she is "forced" to no longer produce milk. When the calf is 6 months old, she will be 3 to 4 months pregnant. A dairy cow, on the other hand, will be lactating until she is 2 months away from her next due date to deliver her next calf, which means she will be giving milk for 10 months after the birth of her calf, then be dried up when she is 7 months into her pregnancy. Some beef cows will be allowed to have their calves suckle them until they are 10 months of age. A lot of where people think that pregnant cows are dry cows is from what they have learned about human pregnancy and the fact that women are not lactating when they are pregnant. This is like comparing apples to oranges and should not be used as a way to compare the reproductive physiology and workings of a cow versus a woman. Thus one should not think that just because a cow is pregnant she is not still giving milk.
A cow will get pregnant once a year starting when she's around 15 to 24 months of age. So, if a cow lives up to 20 years of age, she may get pregnant 18 times during her life.
Yes. After a cow has calved, she will usually lactate for 10 months before being dried up to ready her for the birth of her next calf. During that 10 months, around three months are alloted for that cow to come back to normal cycling and let her uterus shrink back to normal. By the time those three months are up, she is ready to be bred and settle to gestate for nine and a half months before giving birth to her next calf.
Copulation or conception. This occurs when the bull ejaculates sperm into the cow, which encourages a series of events that allows a cow to become pregnant and give birth to a calf over 9 months later.
It is possible for there to be mucus and blood in cow's milk. In fact, most milk that Americans drink contains at least some white blood cells.
