Milk does not produce phlegm at all unless you are allergic to it. It's an old wive's tale. Fat can thicken phlegm, so if you drink whole milk you may see an increase in thickness, but it does not produce it. But that would be the case for any high-fat food you consume, not just milk.
There is a good article in the New York Times about this myth: http://www.nytimes.com/2004/08/10/health/really.html
I feel that when I drink beer while I am a bit sick I do produce more phlegm
No. Female humans do not have the capacity to produce that much milk. Humans are not cows.
Jerseys produce around an average of 20,000 to 30,000 litres of milk per year.
It requires 88 pounds of feed to produce 100 pounds of milk
Because their milk is in much higher demand than human milk.
A Belted Galloway cow can produce as much as 20,000 lbs. of milk per year or 9,000 liters of milk per lactation. The milk has very small fat globules which renders it partially homogenized.
No. Only mammals produce milk for their young. The only birds that produce milk are pigeons.
300,00000
one Ayrshire can produce six gallons at lease.
Modern Marvels told me they can produce up to 1000 lbs/day with 56% milk fat.
A goat doesn't produce cheese. It produces milk, in which cheese is made. The process of milking a goat is similar to that of cows, but on a much smaller scale. The cheeses made with goats milk are much easier to achieve than that made from cows milk. A sheep doesn't produce cheese but there are certain breeds of sheep that you can milk and from this milk cheese can be produced.
If it is phlegm from being sick (if it is yellow or green) then take a decongestant or gargle with warm salt water, which breaks up the phlegm and kills the bacteria that produce it.
