Literature sources state as numerous as 50% that domestic cattle have an ext than four teats, well-known as supernumerary teats. Extra teats might be component of a very small milk gland, or have no milk gland underneath. This is not distinctive to cattle, and is one of the mysteries that the advance of mammals; in fact, countless humans have more than two nipples, but do not realize it, thinking they have a tiny brown mole on your chest or abdomen.

Normal teats and extra teats monitor the very same “milk line.” The milk line is two imaginary rows along which teats can type on the occurring fetus. This is why the extra teats on cattle typically form in a line behind the primary four teats, in the very same row formation.

Dairy cattle are selected for basic machine-milking, and “show cattle” room selected because that a clean appearance. Both objectives usually result in the remove of extra teats, best in a very young calf. Since most advertising dairy livestock are dehorned as calves, dairymen simply check for extra teats at the time of dehorning, and, if present, snip them off.

HOW room EXTRA TEATS INHERITED? This has actually never to be determined. The is clear extra teats are not a single-gene characteristics that can be conveniently “bred out” like, say, PHA. Some posts refer come an growth of genes that occurred when cattle started to it is in selected for milk lengthy ago. Rather have documented an raised frequency of extra teats in calves born come older cows, and also proposed the exposure of the arising fetus to varying hormone levels may rise or diminish the likelihood of extra teats. Due to the fact that it is unknown just how the properties is inherited, how countless genes contribute, or what other factors are involved; the is very difficult to select against.

This dry cow still reflects a bad rear udder attachment, leading to the udder to guideline forward. Funnel teats room wedge shame on a dried cow, and also balloon out throughout the first couple weeks of every lactation.


DO EXTRA TEATS median THE animal HAS A bad UDDER? A negative rear udder attachment causes the cow’s udder to reminder forward. Weak average suspension causes the teats to point out to the sides. A poor front udder attachment reduces capacity. Funnel teats do it difficult for a newborn calf come nurse and also receive enough colostrum. All these defects end up being increasingly worse with each lactation, do an udder susceptible to injury and daunting to milk or nurse. This defects are virtually unknown in commercial dairy product cattle, however plague our Dexters. Extra teats, top top the other hand, are mostly a cosmetic issue and can it is in snipped off, if desired. They reason no actual damage to the animal.

DO EXTRA TEATS median THE pet IS more LIKELY TO develop TWINS? No.

SOME COWS HAVE lacking TEATS:

The opposite case is as soon as an animal has less than 4 teats. This is a lot rarer occurrence, and has number of causes.

In some instances of a congenitally “three-teated-cow,” the gland is present yet has no equivalent teat, as result of a trouble that occurred within the developing fetus. It is typically a former teat the is missing. The absence of a teat will result in a 4 minutes 1 that will engorge with milk once the cow freshens, but because there is no exit allude for the milk, the milk will certainly be resorbed and also the quarter will cease to it is in active. This bicycle will typically repeat for each lactation.

Occasionally, a teat is bitten-off by one more calf sucking top top a young heifer in groups of bottle-fed calves. This is different than a congenitally missing teat.

Another cause of a lacking teat is in reality a severe situation of poor teat spacing. If girlfriend look in ~ an affected animal closely, 2 teats native the same side of the udder are so nearby together, they have actually fused. Periodically there is proof of the fusion: There might be two orifices in the “super-teat,” or there may even be a vertical cleft. Return this is still an problem with fetal development, that is not practically as random together an missing teat. Typically, the unify teat occurs in bloodlines that have evident issues through teat spacing, and also the cow frequently has closely spaced teats on the contrary side.

It is important to keep in mind that teats may additionally be amputated in one adult animal due to negative udder configuration (pendulous udders can be stepped on once the pet is obtaining up) and additionally may be lost as a an outcome of excessive frost bite.

NOTES: Udder configuration is of good importance in both beef and also dairy cattle, as proper udder conformation enables the animal to offer a long productive life.

Extra teats are usual in cattle, deserve to be quickly removed, and have very small impact top top the animal if they are not removed. Udder selection in Dexters has actually been doing not have through the years and there space very few Dexters who have extra teats as their only udder imperfection.

Missing teats are much rarer, but probably an ext serious. Sometimes missing teats stand for a fused teat early out to poor teat spacing in the bloodline. Negative teat spacing makes it complicated to milk the animal by hand or machine; and also in major cases, the calves must suck two teats in ~ once.

Udder attachments have to be solid in bespeak to save an animal productive for the long abundant lifespan we intend from Dexters. Without proper udder support a cow’s udder will certainly fall below her hocks; risking injury, limiting movement, and also making it challenging for her to be milked or nurse a calf.
