Do male cows have udders?
The answer to both questions of whether male cows have udders and “do male cows produce milk?” is no. Only female cows have udders in order to feed baby calves milk. On the other hand, their male counterparts or bulls only have nipples, no developed breasts, so they don’t have any udders.
Similar to other mammals, both cow sexes have nipples except for the male individuals of some species consisting of horses, rodents & monotremes such as platypus and echidna.
What makes the difference between male and female mammals is the formation of mammary tissues which attributes to estrogen, a hormone typically identified with females.
Without these specific tissues, the mammal individuals only have nipples and not breasts, udders, or mammary glands which are made of 50% fat.

Udder development in bulls
Udders are made of mammary glands, which are similar to human breasts. They contain four glands that are grouped together in a single organ. Each of the glands includes a long teat, similar to a nipple, that drains the gland while a calf suckles it or when a farmer milks it.
Bulls don’t have udders since this structure grows as a female cattle reaches sexual maturity and is exposed to substantial levels of estrogen.
In short, what sexually differentiates female cows’ bodies from bulls’, their male cohorts, is the former’s estrogen-based endocrine systems that are developed at puberty.

How to identify a bull, steer, heifer, and cow?
Many people have mistaken that all the male cows have horns, while female cows do not. This assumption is not true. In fact, not all male cattle have horns.
Therefore, others resort to udders to distinguish between male and female cows. The general belief is that males don’t have udders, while females do, however, not all female cattle have udders.
This confusion can be solved with our tips below.
A bull
A bull is defined as a grown male bovine with intact testicles. They are utilized for breeding purposes.
Bulls are colossal creatures, and it’s fairly straightforward to identify a bull among his herd. Bulls do not all have horns. You can only tell whether a bovine is a bull or not by looking for a big sac located between hind legs.
Moreover, bulls typically have more muscular shoulders, neck, and backside than cows. Additionally, the bulls’ penis in the navel area is also what sets the male cattle from their female counterparts.
A steer
A steer is largely similar to a bull except for the intactness of testicles since he has gone through castration before puberty and is mainly used for beef production.
Steers are largely the same as bulls, except for the testicle sack between their hind legs and significantly less defined sheath.
Furthermore, steers have a more feminine appearance than bulls, since they don’t have the typically muscular neck and shoulds like bulls.
A heifer
A heifer refers to a young female cow from under 1 to 2 years old that has just passed the weaning stage, never given birth to any calves, and doesn’t have udders.
Heifers don’t have reproductive organs such as a penis and testicles like male cattle.
When compared to cows, their more mature version, heifers have almost nonexistent udder with small teats between their hind legs which are hard to notice under you are close to them.
Similar to cows, heifers have a vulva under their tail and below their anus, however, its size is small and less developed than that of adult female cows.
A cow
On the contrary to a heifer, a cow is a mature female cattle that has delivered no less than one or two offsprings.
A distinguishing feature of cows is their udder. An udder is a pink organ with four teats between a cow’s hind legs.
You can also tell if a cattle is a cow by looking for her vulva which is located under her tail and below her anus. Heifers also have this, but the vulva size of a mature female bovine is bigger than that of a young female counterpart.

Final words
“Do male cows have udders?” No, they don’t, and only cows, that have mammary glands, do.
Going above and beyond, we also suggest ways to distinguish between bulls, steers, heifer, and cows. The general rule of thumb is to pay attention to their sex organs like penis, testicles, udders, and vulva in terms of existence and size.
