Ok - following my mares attack last year she has been kept on the diet recommended by the laminitis clinic - which is Happy Hoof and Speedibeet (weighed amounts) and Formula 4 Feet. This spring I have also been using Laminitis prone from Global Herbs.
The Formula 4 Feet comes in a huge sack for £75 pounds and it lasts just over 3 months (will depend on the size of horse/pony) and the Lami Prone is about £20 a bottle and lasts a month - but you only use that for when the grass is growing - so about 3/4 months in the spring and then again in the autumn.
This diet and combination have kept her sound and lami free *touches wood* and able to be out 24/7 this summer (on a starvation paddock) and she is back in work and is still unshod. Very pleased with regime and the results (as is my farrier).
I have taken a pony on that has had laminitis on and off for the last 3 yrs. I've had him since just before Christmas and so far, after a months box rest) he is lami free. He gets a scoop of Happy Hoof a day plus soaked hay and is on an almost bare paddock for majority of the day and gets a hour or so on the grass in the evening and thats it. No supplements at all. I just keep his weight down below a certain weight and so I can see his ribs.
So far so good...
Little Lad is laminitic. He's out on good grazing about fifty percent of the time, small bare-ish paddock the rest. He's ridden most days for between an hour and an hour and a half.
His weight is well down from what it was when he last had an attack (last January).
