A cow would already have an udder since she is a mature female bovine, so it's impossible for a cow to grow an udder.
That said, however, a bovine must be female in order to be able to grow or develop an udder. No males, be they bulls or steers, can grow udders. For that female bovine to develop an udder, she must become pregnant at a suitable age (~15 to 18 months old) so that she can begin milk production when she is in her last trimester of pregnancy. Heifers (so are young female bovines called) will begin to develop an udder usually in their second trimester of pregnancy, and this development is primarily of mammary tissue, not yet lactation fluid (milk). Milk production doesn't actually begin until she's close to calving.
The size of udder a cow will develop actually depends on the breed and the genetics for milk production. Misconceptions about milk production would make you believe that hormones given to cows force them to grow larger udders and more milk. This is truly not the case, although rBST injected to American dairy cattle does encourage greater milk production. A dairy cow has a larger udder than a beef cow simply because she has been bred and selected for greater milk production than that beef cow.
Yes, cows udders can get sunburned. Cows that have pink udders, or no pigmentation on their udders are more susceptible to getting sunburned.
No.
NO.
Usually this is an indication that either the cows' udders are so full of milk that she needs to be milked immediately.
In their udders.
Only cows and older and/or pregnant heifers are capable of developing udders; steers, bulls and calves are not.
NO. Cows only have ONE udder, and on that udder they have four teats.
Cows like all mammals have breasts, they have udders, and there used to milk the cows.
That is because the cows are the mammals, thus they have mammary glands- udders.
Cows don't have four udders. They only have one. They do use all four quarters in that udder of theirs though.
Udder is probably derived from 'under'. You could consider that pigs, goats, and cows all have udders.
They don't have udders like cows.
