I'm just saying what's worked for my guy. He's managed by a vet, so I wouldn't worry too much about it. Also, I never said he needed to eat straight Alfalfa.
In horsey circles & on these forums, you get all sorts of opinions, some good, some bad, some ordinary. So I try to qualify *why* I think what I do, so people can better analyse the information they read. Not saying you're wrong in your particular situation at all farlo, just telling what I think are important considerations when working out what's good or bad for certain horses.
You DID indeed say yours needed straight alfalfa and it didn't sound like you were just saying what worked for yours, but telling what *should* be fed, which was my issue, that I thought important to address. The bit in bold is important, as *balancing* what you're feeding is important, is what I was trying to get across. If your vet is knowledgeable about nutrition, that could well be perfect for your horse, no argument there.
i feed alfalfa to my tb's to help with weight as well. Some people just do not believe in alfalfa at all. If feed correctly its a great addition to a horses diet (who needs it) some horses do not need alfalfa and have horrible results when feed to them. Thats how alfalfa got such a horrible rep.
I think the high protein is possibly the biggest general issue with it, as most horses don't tend to need/do well on high protein diets all the time. Of course it's high energy content can also be a big prob for 'easy keepers' too
. The important bits I wanted to get across are in bold below...
Rice bran is generally thought to be a good additive, but wheat, with the ultra high phosphorus should NOT be fed IMO, unless you're balancing a deficiency/calcuim overdose.
Alfalfa/lucerne is generally a pretty good feed for horses **as PART of a balanced diet**. It is very high in protein, which can be problematic for a lot of horses though. Also calcium & some other nutrients are quite high, so it's important to carefully balance nutrition & supplements based on what's in it. Horses should NOT be fed solely on alfalfa IMO & generally it shouldn't be more than around 1/3 of the forage ration, unless under vet's & nutritionist's supervision.
