I have no experience, my mom lived on a farm and they drank the milk fresh, didn't do anything to it. But I don't know if I could lol, she said it did taste different. But I found this for you
If you milk your cow regularly and maintain a good feeding program, your cow can give you milk for up to 10 months
I also found this
Cows produce milk after giving birth to offspring. There wouldn't be any point in milk production *during* pregnancy, since the purpose of milk is to nourish the calf post-partum, and physiologically the body would see no reason to produce milk without a baby.
So I wonder if you would need 2 cows to get milk year round? Like milk one for 10mo while the other is preg...don't know how long they are preg for...then milk that one and breed the other? Otherwise it looks like there would be a lapse in milk production while they are preg...unless they work like humans and can produce while pregnant if you continue milking? lol I don't know though. So I google
This is what I found haha...I'm bored can you tell? Hope it helps though
Part of the problem seems to be milk from modern dairy farms, where cows are milked about 300 days a year. For much of that time, the cows are pregnant. The later in pregnancy a cow is, the more hormones appear in her milk.
Milk from a cow in the late stage of pregnancy contains up to 33 times as much of a signature estrogen compound (estrone sulfate) than milk from a non-pregnant cow.
And they were saying the hormones in the milk are dangerous....granted that's dairy farms but I would imagine the same would apply if you have the one cow and milked it year round.
