having spent weekend researching simple systems feeds which were recommended by trimmer - I found a lot of stuff madam could benefit from...
1) Total Eclipse - balancer, with linseed meal for skin, brewers yeast for skin and seaweed
2) Lunar Eclipse - linseed and brewers yeast with magnesium in for mooday mares etc
3) metaslim - does what it says on tin.
I emailed them and asked their advice and theyve suggested lucie stalks (as the mixer - its alfa alfa, but unmollassed (lower sugar) and less likely to be an allergen than most other feed mixers - also as its pure lucerne there are no other "bits and bobs" in it), with linseed meal - I thought I was going to be given a hundred and one things - when I queried why, it was because she would be better on a simpler diet to work out what causes an allergic reaction - so quite impressed with that as they could have easily rinsed me!!!!!! (moody mare, with lami/weight issues and bad allergies)
Sorry that was off topic... but they also do a sugar free bucket of treats, which I might invest in - my two love carrots, and they only have thin slices when training, but it can still be rather a lot by the end of bribery time!
