What 'grain' is best?

My mom has our horses on a mix of the grain they came with (from the adoption agency, looks pretty sugary/sweet) and safe choice. Her old gelding (almost 30) is on Safe Choice only (and hay).
Our horses are both arabians, one is 23 and one is 16. Both are overweight IMO!
Is Neutrena's Safe Choice a good food?
I admit I am a little clueless about what to feed horses.

I know dogs though ;)

The hay is great, not worried about that.

We feed ours a low protien sweet feed and beet pulp in the winter. They only get that about 4 times a week, not everyday. In the summer they get the sweet feed after a ride or while being groomed, more as a treat than as feed. They get grass during the summer and hay in the winter.

Most horses don't need grain, IMO... especially grain with high sugar, though, it does depend on how they're worked, and how often.

I feed a no-grain pellet feed (low carb) to my drafts and shetlands. High protein and sugar makes them gain weight easily which puts them at risk for founder. The only reason I really feed this(small amount), for the most part, is so that their systems regularly digest pellet form so that when I give them sand clear, it's no surprise to their digestive system. I'm letting the pellets run out and switching to ground flax seed, though because I'm paranoid.
So, for me no grain, especially sweet.... especially if they aren't horses in sporting.

Thank you. :)
I forgot to mention Safe Choice is a pellet.

I will ask my mom to cut the grain out completely and cut the safe choice down a bit as well.

Both of them are way too heavy in my opinion...they came to us chubby. :)

If your horses are overweight then they do not need grain. Just feed hay and if you feel like they are getting too skinny then start a small grain ration of something like Prime 10, it is a Nurtrena grain as well. I avoid feeding any type of sweet feed like you mentioned. They tend to have lots of sugar and corn. What happens to people when they have too much sugar? They get insulin problems, well horses have the same problem.

Do not take them off the grain full stop, I would gradually take them off it over a couple of weeks. Just reduce the amount feed every couple of days.

Those who get grain get low starch 12% Legends pellets. The stallion only get Alf. Cubes (with beet pulp) twice per day plus about a bale of O&A

If they are overweight they would be fine on hay and a vitamin/mineral supplement...

If you are feeding less then the recommeneded amount of "grain" you are wasting your time and money.

Most horses don't need anything besides good free choice hay and a vitamin/mineral supplement designed to balance the hay type

Than you for all the advice. :)

My mom wants to keep them on Safe Choice but I will have her gradually cut them back if she will.

The Min on Safe Choice is 3lbs if I remember right so if you aren't feeding at least that then you need to change feed to ensure they are getting proper nutrition

Oh ok...thanks.
I better just work him more then. :)
