Answer: The first piglet in the litter is being birthed backward.
Step-by-step explanation:
Farrowing is a term that simply has to do with the action by which pigs give birth. Another term for farrowing is parturition.
As farrowing approaches, it should be noted that the the vulva and the vagina will enlarge which leads to the opening into the womb. When a fecal pellet is expelled from a sow's vagina during farrowing, the first piglet in the litter is being birthed backward.
