The back three-fourths or so of a Charolais bull showing his hairy sheath as well as his scrotum. Fortunately, understanding and recognizing the differences between sexes in cattle isn't difficult. When a male has a large, visible, navel it more-or-less blends in with the sheath, which means he's a boy that still looks like a boy. Underneath The Belly Cows look different underneath the belly when compared to bulls and steers. Since steers are more common than oxen the plural of ox , and for the simplicity of the remainder of this article, we will refer to all castrated bulls as steers. Sometimes, however, navels in both males and females are larger and therefore easily seen.
Since a bull has testicles and assuming he is otherwise healthy he can sire offspring. We know by the presence of the sheath that it's a male, but since we cannot see between the hind legs to know whether or not he has testicles, we can't tell if it's a bull or a steer. Urine exits a bull or steer through the sheath, which is underneath the belly. Depending on the individual the sheath might be large and very noticeable, or particularly in steers barely visible. Females also have an anus underneath the tail, but they also have the added presence of a vulva. Urine exits the body of male and female bovines in different places. A visible navel in a cow might be small and barely noticeable, or quite large. An udder might look less full than this, or it might even be empty, but it is still an udder. What You Call Them In cattle, males boys are either bulls, steers, or oxen. A look at the udder on a cow. The mature males and in particular the bulls tend to be larger than females of the same breed, and exhibit a more muscular appearance.

Since they both have a penis, bulls and steers both have a sheath, which is the external pouch that contains the penis. A cow with horns. When a male has a large, visible, navel it more-or-less blends in with the sheath, which means he's a boy that still looks like a boy. In mature animals these differences are sometimes obvious even to casual observers. So, if you see a bovine urinating, you can tell if it's a boy or girl according to where the urine is exiting the body. In some cases depending on how and when a steer was castrated there might be a small amount of the scrotum still visible. This particular udder is plump and full-looking because it is full of milk. An ox cannot sire offspring. The anus is the outlet of the rectum. Because the testicles have been removed the pouch that contained them, the scrotum, is shrunken and usually can't be seen when the animal is in a normal standing position. Ox - An ox is a male that was born a bull but has had his testicles removed after reaching sexual maturity. However, in these instances it is quite small and "dried up" looking, probably difficult to see, and does not resemble the large, healthy, bull scrotum shown here.
