A herd.
Oestrus synchronisation (UK) or estrus synchronization (US), is when female mammals go into "heat" at about same time. This is induced in cattle to be able to perform artificial insemination or embryo transfer at about the same time for the whole herd.

X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
In a horse herd, the head mare will lead the herd, and the stallion will follow up the rear to watch for danger.
Assuming you are taking about the lead horse in a herd, if it's a female it is called a lead mare or boss mare, if it is a male it is called the stallion since there is only one mature stallion (fertile male horse) in a herd of horses.
The fawn will run with the herd until it is a year old if it is a male.Then the lead buck will drive the little guy away. If the fawn is a female it can stay all its life with the herd.
Mammoths probably had a similar herd structure to modern elephants. Adult males lived alone, but females lived in herds with related females and all their young. The herds would have had a matriarch, or dominant female, to lead them. She would usually be the eldest in the herd.

Elephants live in the forest and raise their young there. Young ones stay with the herd for a few years until they are old enough to fend for themselves. Adolescent males leave the group while females stay with the group forever. The herd is lead by a Matriarch which is the oldest female in the herd. The whole herd takes care of rearing and protecting the youngsters.

It is not sure whether you are asking about national or world cattle population, or a cow herd in general. For the former, that is most impossible to answer. For the latter, a typical cow herd should have at least a 90 to 100% female herd. A 100% female cow-herd is typically bred via artificial insemination. A 90% (or 95%) female cow-herd is bred naturally by service of one bull per 20 to 50 cows.

Often it's not the bull that's responsible for leading the herd, just like in wild horses. The strongest, largest and/or oldest cow is the one responsible to lead the herd from one place to another. It's not really known how an animal knows when and where to lead the herd from one spot to another; possibly some sixth sense, body language from others, or even telepathy could be some possible reasons as to how a lead cow knows when and where to lead her herd. Observations also count as well, as she has to see and smell where the best watering hole or the best grazing areas are for her herd.
