For what the horse needs, she is not spoiled, she is confined. She needs to be turned out 22 hours a day in a good sized paddock or pasture with other horses. This living arangement will "fix" 90% of the cribbers out there (given some time). Riding daily obviously doesn't cut it with your girl, she needs to be at a facility where she can be turned out.
As for weight gain, take her OFF the sweet feed. Any kind of sweet feed and most pelleted feeds contain ingrediants that can cause negative metabolic changes in horses, and will even cause some to LOSE weight. I went through this with my Anglo Arabian gelding (TBxArab). We were stuffing him full of every kind of feed and supplement imaginable to get him to gain weight. What finally worked was a SIMPLE diet!, as follows:
- Free choice GOOD quality grass hay.
- 5-6 lbs of Alfalfa pellets.
- 1.5-2 lbs of Stabailized Rice Bran.
- Source Focus WT.
- Purina's Free Balance
You can change the pellets to alfalfa cubes, chopped hay, or flakes of alfalfa. The Source supplement is a probiotic that helps the horse digest her feed properly. The Free Balance is a supplement for horses getting no fortified grain. You can also use Select II or Smart Pak's Smart Vite. All three are good.
Once she's up to a good weight, you can discontinue the Source, reduce the rice bran to 0.5 lbs, and reduce the Alfalfa pellets to 3 lbs a day. If she still gains weight, you can cute out the rice bran. My gelding no longer gets rice bran and he's doing very well now! He gets less food than I ever thought possible! lol
