when a cow has a calf she gives milk for as long as the calf needs it which is about a year, though it will vary between breeds and between individual animals and until you breed her back and she has another calf will she then produce milk again.
When they're toddlers.
we only breed once a year but goats can have 2 pregnancies a year
Cows are typically bred once a year, with a gestation period of about 9 months. This means a cow can be pregnant once a year and give birth to one calf annually.
Valbazin cannot be used on pregnant cows that are in their first 45 days of pregnancy, nor can it be used on breeding dairy females. If you have pregnant cows that are at least 45 days pregnant, yes, you can use it on your pregnant cows.
Cows should get pregnant an average of once a year. Some can get their cows bred twice a year, or once every 11 months, though it's a more common practice to have them bred once a year or every 12 months. This is due in part to their nine to 10 month long gestation period, as well as the time allotted to allow them to rest and get back into normal cycling before being bred again.
Cows used for breeding only, or cows that are already pregnant.
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.
it should be. or the calf could "get stuck". the vulva will swell prior to giving birth unless the calf comes really early.
No, because cows don't have "breasts." They have UDDERS.
Only if the cow that they're mounting is in heat.
No. Once a cow is pregnant she won't have any signs of heat again, until after she gives birth to her calf.
False heats are rare in cows or heifers that are already bred. If a heifer does go into heat when pregnant, it only occurs once or twice and that's it. But normally, no, a heifer won't still mate when she's pregnant.
