Yes, if there's more than one bull around, or if the bull trailing her is very promiscuous.
Yes. A bull will mate with a cow more than once during her heat cycle if he is so inclined and if he has few other cows to mate with.
Only once is necessary to get her settled. However, during a heat period, one cow can be bred to multiple bulls (if there are that many) more than once during her heat period.
Hopefully only once. A healthy cow should be able to be settled on only one breeding session to conceive a calf. If there are more than one bull present and she is in heat, she will most likely get bred by more than one bull.
Because it's likely she's already settled and doesn't need to be bred again. Cattle are not like humans where they have sex for pleasure. If a cow is not in heat and not demanding a bull's attention, then he will leave her alone and go find other cows that are in need of his services. Less experienced bulls, like those yearlings, may try to breed the same cow over and over again, but eventually grow out of this once he discovers that he can breed more than just one!

Staffordshire bull terriers are commonly given the nickname "Nanny dog" because of their fondness for and gentleness with children.
No a falcon will only breed once in the spring.
English Bulldogs were breed for baiting bulls in preparation for bull fighingt. Once bull fighting became outlawed a few individuals decided to continue breeding the dogs and breed the aggressiveness out of the breed. Now the breed is known for it's companionship and loving nature expecially towards children and other dogs.
Firstly, a general rule of thumb is to not mate your dog with her first head, but only with her second heat at the earliest. Before going into heat the female will show signs by having a swollen vulva and this will be followed by blood. If the blood is red she has just started with her heat period. Only once the blood becomes more a straw colour is she ready to mate. On which day this will occur varies with individuals, on average most females takes 11 days before they are ready to breed.
That's real easy. Breed the Charolais cow to a Brahman bull and you'll get your F1 Charbray calf. Mind you, it's a 50-50 chance you'll get a heifer (which will "turn into" a cow once she has a calf) over a bull, so you may want to breed the dam until you get a heifer from her, if all she throws is bull calves. Either that or get more than one Charolais cow (preferably over 50) and breed them to the Brahman bull to get your Charbray cattle. Also, Charbrays are actually 5/8 Charolais and 3/8 Brahman, so you might have to breed the F1 offspring back to a Charolais bull to get a true Charbray cow...or bull.
A bitch will go into heat twice a year however its really only safe to breed her once a year. A male you can breed as often as you want.
A dog must be in heat to get pregnant. Heat is basically her ovulation cycle.
I would say no because once their pregnant they don't go into heat
NO
