It is entirely based on the cow's genetics and breed. They have spots because their parents had spots or maybe the cow's parents were different breeds and the resulting mixture was spotted colouration. The breed you are thinking of that has spotted cows would most likely be Holstein. Other breeds include Milking Shorthorn, Shorthorn, Texas Longhorn, English Longhorn, Normande, Florida Cracker, Speckle Park, Beefmaster, Simmental-Fleckvieh, Ayrshire, Guernsey, and many more.
If you are talking about a different type of spot like warts or ringworm or mange then your cow is in need of a veterinarian.
Black blotches are a result of the breed characteristics, the DNA of the animal, and the pigmentation of the hair. An example of a breed with black spots is the Holstein. The breed characteristic is black spots, the DNA and the pigments of the hair determine where and how the spots are placed on the body.
Animals have spots that blend into their environment, just as hunters use camoflauge jackets. The spots on the animals have the same affect. It is hard to see them when they are either hunting or being hunted. Household animals have spots from their ancestors. Although camouflage is certainly a factor, certain coat patterns appear to play a role in repelling biting insects.
Not all cows have spots - Holsteins (the large dairy cows common in the United States) have large black spots across their body. Several other breeds, such as British Whites (a beef-type breed that is not as common in the United States) has small black spots across their forequarters.
The spots are likely to be genetic freeloaders. As the cows were bred for some other characteristic, the spots came along because they were physically close to the genetic trait being selected for.
Another hypothesis, which is relatively recent, is the spots may be a marker for some disease resistence. As the cows were bred to produce more milk and stay healthy, the genes that keep the cow healthy may also produce the spots.
Not all cows do, only certain breeds. And it's all due to genetics.
Genetics. Not all cows have spots on their bodies; it all depends on what breed or breed mix they are that determines whether they should have spots or speckles on their body or not.
That all depends on the breed.
No.
Big splots of black.
poisonous puss
they are light colored with brown blotches bordered with black.
no the turtle won't but the gold fish sure will .
Some cows have black spot. some have brown spots. Some times it could be a black cow with white spots.
No. Black Angus cows are all black. You can only get black cows with white faces if they have a sire as a Hereford or traditional Simmental. These cows are called "black baldies" and should never considered as purebred Angus because they are not purebred at all: they are crossbreds.
No. Some have white rumps, others have patchy black-and-white rumps. A few have black ones.
One in every five cows would have black and white coats in this herd. Using this ratio you can determine how many black and white coated cows would occur in similar herds of differing sizes.
yes
It is a normal eye color for them some may be brown but look black, it is very very normal in a cow.
Yes. Ever heard of Black Angus? That is a breed with black cows. Same with Galloway, Dexter, Kerry, and others.
holsteins.they are black and white cows
