This is the period where the cow is producing milk, and is always after giving birth to a calf.
Lactation is a term for the time period that a cow, or any other female mammal, is able to produce milk. What defines such a period is by seeing how tight and swollen the udder is on that cow. If the udder looks tight and swollen and all four teats look full, then she is obviously in her lactation period. This goes for all types of cows, beef and dairy alike.
For beef and dairy cows, lactation period begins immediately after a calf is born. For beef cows, the lactation period ends when their calves are weaned off of them. For a dairy cow, the lactation period ends when she is not longer being milked and allowed to dry up so that she can focus on putting energy into growing the calf inside her. The dry period for a dairy cow is shorter than a beef cow's: two months for a dairy cow, and four to five months for a beef cow.
"Per lactation" refers to each period that a cow is producing milk. The majority of cows lactate for 6 to 10 months of the year, depending on the type of cow (beef versus dairy) and how long a producer wants her to be lactating for.
The length of lactation in an Angus cow is for as long as she has her calf on her, which is around 6 to 10 months.
The average cow in Wisconsin produces roughly +20,000 lbs a year in lactation.

The term for a fear of cows would be Bovinaphobia, from "Bovine" meaning cow, and "phobia" meaning fear.
Cows finish lactation when they are being dried off; i.e., when they're weaned form their calves, or when the dairy farmer has to dry them off to give them rest before calving in two-months' time.
Domestic, non-dairy ewes typically lactate for 90 to 150 days. Dairy breeds will lactate for 120 to 240 days, thereby increasing milk yield per ewe per year.
Polled is a term meaning the cow has a gene that they will have no horns. Unpolled is the opposite; they have the gene to grow horns.
