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.
In America, yes.
What Angus cow? There are many different cows from different ranches, all with different reg. #'s. Please be more specific! Check out the American Angus Association website for the Angus cow you are looking for.
Angus beef does not come from any part of any cow, but comes from a BREED of cattle (or cows) called Angus.
An Angus cow is exactly the same as a chicken or a flying pig that meows.
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.
The inclusion of the Angus bull is irrelevant to this question since the bull has no control nor part in the length of a cow's gestation period. Expect a Hereford-cross cow to have an average gestation period of around 285 days long, plus or minus a few days.
A healthy, fully mature Angus cow can weigh anywhere from 1200-1600 lbs.
An Angus cow only produces around 20 to 30 lb of milk per day.
This is the period where the cow is producing milk, and is always after giving birth to a calf.
"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.
