Once every 11 to 12 months, accounting for the period of rest a cow gets after being bred (which will last from 2 to 3 months), and the gestation period for that cow after she has conceived.
The same as any other cow that lives elsewhere in the world: one year in between calvings.
A cow that is very close to calving or which calving is imminent.
Calving.
A breaching cow could mean a cow that is calving out a backwards calf.
Yes, always.
A cow that is close to calving, and is far along in her gestation period.
The Calving to Conception Interval (CCI) is the period between a cow giving birth (calving) and her successfully becoming pregnant again (conception). It is a crucial measure in livestock management, particularly in dairy and beef production, as it directly impacts the reproductive efficiency and profitability of the herd. A shorter CCI can lead to increased milk production and faster turnover of calves, while a longer interval may indicate reproductive issues or suboptimal management practices. Monitoring and optimizing CCI can help improve overall herd health and productivity.
Parturition or calving, just like with any other cow.
the cow will get restless and will isolate itself from other cows.
A calving pen, or out on the pasture.
For one cow, it's usually 11 to 12 months in between each calving. For a cow-calf operation with defined breeding and calving seasons, it's always 12 months in between the start of one season to the start of the next.
Absolutely nothing. A pig doesn't care nor cannot help a calving cow.
