It seems to me most of the above people feed so many different things to balance their horses rations so they get the proper ratios of nutrients. I have a hard keeper and he was 300 lbs underweight when I got him and he was growing so I had him on 6 lbs of rice bran 12 lbs of beet pulp (dry) and 8 lbs of LMF showtime as it is high in fat and balanced. Now that he is at an even weight he is getting 10 lbs LMF Gold which is a complete feed and balanced correctly to match the hay in California. For supplements being young all he gets is electrolytes, platinum performance to keep him on top of his game and a vitamin B complex to improve nerve function as he has a tendency to get his mind so full he doesn't know what to do with himself. For roughage he gets12 lbs of grass hay for breakfast, 5 lbs of grass hay pellets for lunch and 6 lbs of grass hay and 8 lbs of alfalfa for dinner. If anyone lives in California or Oregon LMF Gold is a miracle feed I recomend it to any highly conditioned event or endurance horse or a hard keeper. I introduced it into my barn full of eventers who were feeding way to much concentrates to keep weight on their horses and now they all feed LMF Gold and our ulcer rate has gone down, we feed ALOT less grain and our horses seem healthier and happier with more balanced temperments.
