Today my saddleback sow had her 2nd litter,but 1 piglet was born deformed its front legs would not straighten out,it looked like a dolphin.Has anyone else experienced this before,if so what is the cause.Secondly the umbilical cords on all the piglets were really long over 12 inches maybe 18.Any suggestions,inbreeding can be ruled out as the sow is a saddle back and the boar was a large white pietran.
