Causes of dystocia

1、Labor dystocia

When a sow farrows, the first 2-5 piglets are born normally, but the interval between piglet births is significantly prolonged, and the sow may even not have any farrowing behavior and fall asleep on the farrowing bed, with the interval between farrowings exceeding 1 hour. This is a clear manifestation of insufficient sow labor, which is more common in sows of older gestational age and is prone to occur when the farrowing process is too long.
