Pig with piglets

I got the impression that pig breeding is the basis of the economy in all Balkan countries. That part of Serbia where we stayed is even called: Swinski Srem (Unlike Srem Vinsky). I was deeply impressed with pigs.
One Serb, our friend, told me that when a sow has thirteen piglets born (I concluded that mamma has twelve nipples), the thirteenth piglet has to fight with her brothers to get her portion of milk.
The picture remained in Serbia.
