This is my first post so please be kind and I hope I am in the right place.
Here is the dilema, I have 3 pastures each with a group of 5 mares. First 2 groups are uber fat, all thoroughbreds or crosses and vet even thinks they are alittle too overweight and are just out on pasture and watertubs and run-in sheds.
3rd group is my problem child group. Mix of Thoroughbreds, Morgan and a TN Walker. 17 acres, tree line on 3 sides for protection so no run in shed, creek and natural spring so no water tub. These mares are losing weight. They are not skinny mind you but could use 50-100 lbs each not like the other 2 groups of fatso's. They also are not eating the pasture down to barespots. (I know that is not good to have done, but in each of the other groups, you can easily find the good spots where they graze the most) 2 of the mares have rashes on their noses as well. Vet told me to mow the pasture down to about 2-3 inches and give them another month. Pasture is now about 6" tall and is starting to grow flowers or the grass is getting seed heads. He didn't seem overly concerned but I want to stop this now and not when they lose another 50 lbs.
Ideas, thoughts, suggestions? If it was only one horse I could find a reason but all 5? I am missing something here and vet is less than helpful
