The correct term used to describe the process of giving birth in farm animals is "parturition". This process refers to the act of delivering young offspring, such as calves, lambs, piglets, or chicks, from the mother's uterus to the outside world. During parturition, the muscles of the uterus contract and push the fetus through the birth canal until it is born. It is an essential stage in the reproductive cycle of farm animals and is carefully monitored by farmers and veterinarians to ensure the health of both the mother and offspring.
