it takes 1 year for it to be born
From birth, a calf will constantly need milk from the cow for 2 to 3 months. By the time they are old enough to eat on their own, they are fully weaned from their mothers by the time they are 6 to 10 months old.
As soon as the sac is torn away they nurse
The umbilical cord is ruptured when the calf is born. The remainder of the umbilical cord will fall off the calf after a few days.
It should take no more than a couple of weeks for her to dry up.
There is no fixed time that a baby giraffe stays with its mother. The calf may nurse for a month or for as long as a year, because they usually find food on their own. Giraffes often engage in calf groupings, or nursery herds, where a mother will leave her calf with other giraffe mothers while foraging.
A cow and calf should not be separated unless you are weaning them. Thus, if you are asking about weaning a cow from her calf and vice versa, you should keep them separate for at least 6 to 8 weeks, longer if the calf tries to go back to suckling his momma again when you put them back together.
Only if a long time has passed since the calf was weaned or the calf will nurse again. Usually, once at least 6 weeks have passed, can you put a cow and calf back together again.
The umbilical cord is ruptured when the calf is born. The remainder of the umbilical cord will fall off the calf after a few days.
A calf should get colostrum within an hour or so after birth. Colostrum in the cow will be produced for the next 24 to 48 hours after the calf is born, but at eat time frame, the quality of the colostrum decreases, which means that if the calf receives its colostrum after 24 hours or more, its ability to survive, and grow into a healthy animal will be diminished. It's CRUCIAL that the calf gets his colostrum within a couple hours after birth, if he is not up and suckling (or has not been up and suckling) by the time you next check on mom and calf.
That depends on the breed and birthweight of the calf. Every calf is different, and have different lengths. On average, though, a calf may be about three to four feet long from the tip of the nose to the tip of the tail.
Almost immediately if that's the purpose of the calf--for meat and not breeding.
