Why do they lose wt in the winter?
Because they need more food to keep warm and handle the weekend riding. If they're losing weight, then they're not getting enough food to sustain them. Try increasing the hay to 1/2 a bale each. You can also add some alfalfa pellets to alfalfa hay for increased calories. Feed a coffee can of the alfalfa pellets along with the allegra and see if that helps, or feed 1-2 heavy flakes of alfalfa per horse per day.
Our two have been doing fine on a 1/2 bale of GOOD quality grass hay a day (fertilized hay, high protein). We feed them 2-4 times a day, depending on how much we're home. They also get one 2qt scoop of chopped pre-bloom alfalfa hay, 1/2 of a 2qt scoop of whole oats, and a vitamin supplement. No grain, no feed, no extras. This simple diet seems to keep the weight on better than when we used to feed extra grain/feed to them.
