The first milk that comes from a cow right after calving is not suitable for human consumption. It's gathered from the cow and saved for the calves that have been taken from their moms and fed to them via the bottle. The first milk is called colostrum, which is important for a newborn calf's health and survival.
The udder will only swell, the cow is dropping her milk into the milk cisterns in the udder for the calf to suckle.
A cow that is very close to calving or which calving is imminent.
In terms of what, quantity of milk? Butterfat? Milking ability? Temperament? Calving ease? Please be more specific.
A cow SHOULD be producing milk after calving, since this is the kind of liquid that calves have to live off of for the next few months of their lives, or until they are weaned. All cows HAVE to produce milk after they've calved, no exceptions, no matter if they're a beef cow or a dairy cow. However, a cow that is not producing milk after calving is a cow that could be malnourished (being too thin) and doesn't have the reserves to produce enough milk for her calf, or she's too fat, with too much fat deposits in the udder that are hindering milk production. Or, that cow is not being fed proper nutrition, and this is also causing her to not be lactating properly after birth. You will have to bottle-feed the calf until either the cow has been fed adequate nutrition enough to help her with proper milk production, or until he's old enough to be weaned while you put the cow on the cull list and give her a one-way ticket to the salebarn.
Calving.
A breaching cow could mean a cow that is calving out a backwards calf.
None. Calving is too stressful an event to let a cow give milk during such an event. Afterwards, and only afterwards, will she be able to relax enough to allow milk-let-down to commence.
No, a cow does not give milk every day. A cow's ability to produce milk is dependent on a variety of factors such as its lactation cycle, diet, and overall health. Typically, a cow will produce milk for about 10 months after giving birth before entering a dry period to rest and recover before calving again.
Yes, always.
There's really no name for such a thing. All it is is that she's just ready to give milk to her newborn calf.
A cow that is close to calving, and is far along in her gestation period.
Colostrum is the first milk produced by a cow after giving birth and is typically present for the first 2 to 3 days postpartum. After this period, the composition of the milk changes, and the cow begins to produce regular milk. The exact duration can vary slightly depending on the individual cow and her lactation cycle. However, colostrum is generally not present in significant amounts after the initial days post-calving.
