I've been feeding a mixture of sweetfeed/pellet in a 10% protein level for well over 20 years. I've never had a horse colic from it nor have I had any behavioral problems associated with it's use. My horses are turned out 24/7 and when pasture is in poor shape I supplement with hay. If a horse is in need of weight I will feed about 2 1/2lb x 2 per day (I actually weigh their feed). As they come up to the proper weight I'll cut back, when I'm comfortable that they are maintaining, to about 1/2lb X 2. I'll adjust according to the work load and their weight.
When I got Bobo (pedigree listed in my signature), as an example, he was about 100 lb under weight and it took about 2 months to build him up. I ride him about 5 days per week and I now have to keep him in the paddock at night rather then the pasture because he is gaining too much weight. Foraging is still the best way to put weight on a horse but sweetfeed should not be a problem. And I think it gets a bad rap.
There are always examples of sweetfeed problems as Luvs2ride had but there can be problems associated with any feed.
