They are alfalfa based (lucerne). Protein is 15,5% which is too high for an adult (13% would be right), I can't see how much fibre 19% is suggested minimum, this feed also has many additional components I wouldn't honestly want to use it, I think it is more for rabbits raised for commercial breeding, they live short life and need to gain more weight as for what they are raised for. If I had no other option because of the situation and it is not clear how long it will be with us, I would probably feed just hay and vegetables/greens you can grow yourself, if you decided still feed this I would give very small amount daily as protein is high and your rabbit can get fat quickly, also too high calcium 1.2% which can cause bladder sludge, lots of grain and unnecessary components listed. I didn't check vitamins yet but I have a feeling there can be too generous amount as well.
Also daily portion stated 200 gram for 5kg rabbit. That is he'll get lots of protein and calcium and vitamins and as you say fibre only 15%.
I wouldn't suggest for your pet rabbit tbh. Feed him unlimited hay and limited greens/vegs and he'll be fine.
