My mare was recently diagnosed with significant gastric ulcers. I have had horses in the past with ulcers, but not as significant as hers are. We are starting with 28 days of Gastro Gard, Neigh-Lox, Alfalfa, and as much grazing as possible. I understand that the best thing for ulcer-prone horses is to live out and not have grain. Unfortunately my mare would not be able to live like that. She would walk off all her weight living out. Right now, she is turned out weather-permitting, and is on about 5.5 pounds of 10%/10% textured feed twice a day and I would like to still see her put on some weight. I plan on increasing the amount of times per day she is fed, and changing her grain to something with low starch, high fat? I am wondering what grain is best for ulcer-prone horses aka what is easiest on their stomach with weight-gaining properties? If anyone has any expertise in this area - please let me know! My mare is a 12 y.o. OTTB that does the jumpers. Thanks!
