The hormone that influences the movement of the pelvic ligaments during parturition in farm animals is known as relaxin. Relaxin is a hormone produced in the ovaries and placenta of pregnant animals, including cows, pigs, and dogs. It causes the ligaments that support the pelvic bones to soften and stretch, allowing the pelvic opening to widen during birth. This allows the offspring to pass through the birth canal more easily. Relaxin is also involved in other aspects of pregnancy, such as regulating the growth and development of the fetus and preparing the mammary glands for lactation.
