Only if the cow that they're mounting is in heat.
Same way all bovines do: Bull mounts cow and inserts his penis into the cow, ejaculates then dismounts.
Yes. That's the only way you will get a calf. Breeding a cow to another male animal (except a bull bison or carabao) will not get her pregnant.
Cows mate through natural breeding where a bull mounts a cow to copulate. This process usually occurs when the cow is in estrus (heat) and ready to breed. It is a natural behavior in cows for reproduction.
You can't, unless you make the bull a steer.
you must buy the fertilizer and then use the cow with the bull you want but you must put the cow and the bull only in the barn or only them outside. It is more effective in the barn.
Sometimes, if her pheromones are producing more estrogen than usual. But most pregnant cows won't have anything to do with a bull.
Copulation or conception. This occurs when the bull ejaculates sperm into the cow, which encourages a series of events that allows a cow to become pregnant and give birth to a calf over 9 months later.
No, not usually. On rare occasions, a cow may experience false heats during pregnancy where she can be ridden by a bull, but otherwise, a cow that is pregnant stays pregnant and doesn't go into heat until a couple weeks after she's given birth.
The opposite of bulls are cows or heifers. Bulls are male, cows are female. The difference between a heifer and a cow is that a cow has been pregnant.
Cows can get pregnant through the process of mating with a bull, where the bull inseminates the cow. This can happen naturally through natural mating or artificially through artificial insemination by a qualified professional.
Yes. A barren cow (one that is open, or not pregnant) is able to come into heat or estrus.
By getting bred by a bull or having an AI tech insert bull semen into her uterus. See the related question below for more information.
