Making the world better, one answer at a time. The average gestation period for a pig is 114 days. The actual labor can take as little as 15 minutes and as long as 5 to 6 hours.t takes about 5-30 minutes for a mother to give birth to her baby(s). If it takes longer than that you have to get some help or go to the vet because if you don't the female â¦ guinea pig could die. Or the baby would have problems with it brain.
How long it takes for a cow to give birth really depends on her body condition, her experience, how big the calf is inside her, environmental conditions, and whether the calf is presenting normally or not. As a result there really is no set-in-stone time it takes for a cow to give birth. For experienced cows, it's only a matter of 5 to 6 hours until the calf arrives. For a heifer, it can be a few to a number of hours longer. See the related question below for a similar answer. If, by any chance, you are asking how long a cow is pregnant in days, the average is around 285 days long. Please see the related question on the length of gestation below for a more detailed answer.
