Only once.
Pigs can breed multiple times a year. Sows can have multiple litters in a year, with an average gestation period of around 3 months, 3 weeks, and 3 days. They can typically produce 2-3 litters per year.
Friesiens, and all cows for that matter, can breed and subsequently calve in any month of the year. Cow fertility typically suffers in hot weather for most breeds, so births tend to slack off 9.5 months after the hottest part of the year. Most North American beef ranchers breed their cows in early Spring, so the calves are born in late Winter.
Cows typically give birth once a year. The gestation period for a cow is around nine months, so they will usually have one calf per year.
It is important that you do not over work the bull, usually in a period of 8 hours about 3-5 is a good number for older bulls. For a better understanding, the ideal bull to cow ratio would be for yearling bulls 15-20 cows. 2 year old bulls 20-30 cows; and for 3 year old or older 30-40. This ratio is usually for pasture breeding, when the cows and bull are turned out for the summer months when the bull will then breed them as they cycle.
Cows can typically get pregnant once a year, if they are breed. Their reproductive cycle, called estrous cycle, lasts around 21 days. If they successfully conceive during each cycle, they could potentially get pregnant multiple times in their lifetime.
they breed 1 million times a year
A Piranha can breed up to 200 times a year
Rabbits can breed multiple times throughout the year, with some breeds able to breed every 30 days.
once
I would say once a year!
a buck can breed about once a day and a doe shoud only be breed about once a year
Any cow can have a calf per year, usually cows will be able to breed and produce calves until they are 7-10 years of age.
Like most animals - they breed once a year - usually in the spring.
we only breed once a year but goats can have 2 pregnancies a year
It depends on what kind of fish they are; tropical fish will reproduce many times in a year, whereas many temperate species will only do so once a year.

There is no way to tell exactly how many cows are killed worldwide each year. It is estimated that 35 million cows are slaughtered each year in the US alone. In Canada, it is estimated that 12 million cattle are slaughtered each year.
