The Signs of Oestrus
Pro-oestrus (When Training, tick off)
  In gilts, the vulva swells, but this is not consistent in the sow.  
  The vulva becomes congested or red.  
  The udder develops in gilts.  
  The female becomes nervous and easily disturbed.  
  She is ridden by other sows, but does not stand.  
  Vaginal walls become reddened (congested).  
  Clitoris becomes more prominent.  
  Vaginal fluids thicken, produce strands between fingers.
