I was just reading about them, they are a swedish breed of cow, acutely endangered and are an awesome breed, giving milk on a low fodder diet. 
I will write more later but I got a late lamb this morning and I have to open the café now.
There are about 1300 of them. Most go up to the mountain pastures for the summer. These are called fäbod.
Traditionally the women moved up to tend them and make cheese, butter etc. for the long winter months.
The products have a fantastic rich flavour and it was thought that this was because of the varieties of herbs and floweres the cows ate. That must also be the case but there have been some recent studies done on milk in Denmark and they have discovered that the milk is actually unique.
I don't know what it means but it seems that the milk has "B" kasein? which produces a much better qualiy cheese. Those from Lillehärjedal which were isolated for a100 year (There are no roads to that farm) even have double "B" One of my heifers come with that pedigree.

Mine arenot as pretty most of them but I will be choosing bulls to give the skimmel that is characteristic.
