Obsalim cattle cards

[Green Grass]

Has anyone got a set of obsalim cards them. Had a independent nutritionist end of last winter as wasn't to pleased with advise from feed companies in previous years. He was wondering around the cow with these cards and seemed to come up with symptom's of poor diet that made a lot of sense to me, mainly lack of fibre and to much quickly fermentable energy. But it was a lot more sensitive than bubbles in slurry and cud balls everywhere. I think they could be useful, just wondering if other people use them and any other thoughts.

I bought a set. It really is a great way to generate random theories, but seemingly backed up with no evidence. I didn't find them especially useful.

They take ages to come.

Anyone using these cards still? How much and are they worth it? Thanks
