There are four teats to a cow's udder. They are used for suckling a calf. In milk production, hand milking may be used, but large scale operations use milking machines (and reserve hand milking for sick cows, so that the contaminated milk does not go into the holding tank).
A fish teat is a nipple that flattens and splits near the end. This type of teat is used in the milking process.
milk dud
on a cow or perhaps a goat you use that to clean of the teat before you would put the milking device on it and after you take the milking device of you clean the teat again
Heifers grow teats when they start producing milk, which is either right before they calve, right after, or during pregnancy. The teat canals make the teat grow bigger because of the milk filling up in the cavity, which is released when the new calf begins to suckle.
Since cows are mammals, baby calves get milk from their mother's mammary glands. These are located below the female cow's rib cage, on their abdomen, slightly forward of their hind legs. They are commonly known as udders, and the average cow's udders have four nipples, called teats. These teats are about as long as a person's middle finger.
mastitis
The Glass Teat was created in 1970.
Yes, Milk SHOULD be sterile when it is still in the udder, just like urine should be sterile when it's still in the bladder. A healthy udder does not have bacteria in it, so is sterile. In this case the bacteria is picked up in the distal teat canal, and the outside of the teat. When the udder becomes infected with bacteria (a disease process called mastitis), the milk is no longer sterile. This is when the cow has mastitis, where bacteria have entered the udder and infected the mammary tissue. Most bacteria in a healthy, non-mastitis-infected cow that does affect the milk are found in the teat canal and enter the milk when the milk is excreted through the teats.
That's an easy one. Of course it has been handed down by verbal tradition through the centuries that a Jewish male by the name of Jesus of Nazareth, King of the Jews and the sworn enemy of the Galactic Germanic Alliance from the Hitlertron Galaxy, was the very first to suckle the sweat teat of a cow.
Only four teats on a cow shouldn't be considered as "many." The advantage of having four quarters--and thus four teats--on a cow is so that the calf doesn't suckle one milk gland completely dry. It also allows the calf to come back for seconds to the other quarter[s] that are still full of milk.
The word "Tit" is a slang variant of the word teat. Teat means nipple.
You need to consult a veterinary surgeon who will prescribe antibiotics as the cow probably has mastitis. Mastitis needs to be treated as soon as you realise that there is a problem. If you act quickly the cow should make a full recovery, but if you delay in seeking treatment from your vet, the cow can lose complete production of milk in that quarter of her udder.
Teat, nipple.
A cow should have four functional teats as maximum. She can, however, have two or more extra non-functional teats, none of which affect production nor milking ability. In dairy operations, though, these extra teats need to be removed so that the person with the milking machine doesn't hook up the vacuum pump to the wrong teat.
