This all depends on your herd size, how long your calving season is, and the fertility of your cows and bulls. Some people will calve their cows 365 days a year, whereas others will have all of their cows calve within a time frame of 45 to 60 days, no matter if you have a herd of 50 cows or 1000. The better fertility you have in your cowherd, the shorter your calving season will be.
The same as any other cow that lives elsewhere in the world: one year in between calvings.
Birthing, or calving.
They weren't. Branding was only done once a year, not twice. (However, twice-a-year branding is only necessary if a producer would have two calving seasons; in the Old West, there was only one calving season per year, hence only one branding-time a year.) Cattle are rounded up so that branding, castrating and thus recording of herd/calf/cow numbers could be done, then again to move cattle that were considered excess or "culls" to the herd could be sold.
At any time of the year, if you have a year-round calving operation. For those on set calving schedules, calving ranges from mid-winter to early spring (grass-fed operations calve around mid- to late spring) and/or around autumn, primarily.
The act of giving birth to cattle is called calving.
Calving is year-round in the dairy industry, unlike in the beef industry. So the only significance is that you can time several group of cows to calve at different times of the year so that you have a constant supply of milk going to the factories.
A cow that is very close to calving or which calving is imminent.
Preg-checking is a method done to verify a cow's pregnancy status, or if a cow is bred or not. This is done primarily by rectal palpation, though other "non-invasive" methods of preg-checking are being practiced, such as blood testing, ultra-sound, timing of heats, or bumping. Farmers also check pregnant cows when they are close to calving. This is so that the producer estimates what cows are closest to calving and when they might drop a calf. It will also determine if they are close to calving or not.
calving occurs when a male goat latches on to a mans ballsack and then the goat eats it
This depends on each individual herd and breed. Some herds have a 60% calving assistance rate, whereas other herds may only have a 1% calving assistance rate. Hostlein cows and heifers have a higher rate calving problems than Angus cows, and Belgian Blues have the highest calving problem rates of any breed.
The age at first calving for this breed should be 24 months of age.
Calving can occur quickly or slowly, depending on various factors such as the size of the glacier, temperature, and other environmental conditions. Large glaciers can have calving events that happen suddenly and dramatically, while smaller glaciers may experience slower, more gradual calving processes.
