Those that feed Brewers Yeast or Magnesium

Not sure about the brewers yeast but I feed magnesium and will do long term, my understanding is you can overdose them on magnesium as they wee out what they don't need.
 
I have been feeding my Westphalian Brewers' Yeast for about 8 months now. She doesn't seem to need a break, although she gets one if I run out before I've managed to buy the next supply. Her digestive system seems to be much better blanaced since starting this regime.

I've read somewhere that if you feed too much it makes their poo runny and you should cut down the amont until the poo is solid again. I've been feeding it (and brewer's yeast) for 2 years now and my two have never had runny poos.
 
Magnesium should be balanced with other vits and mins by feeding excess you will unblanace the likes of calcium and cause other issues.

I have also heard of heart arrythemias in some horses which are over fed magnsium.

If you are supplementing it you should be doing so to adress an imbalance it will have no affect if an imbalance is not present.
 
As Maccachic says, I understood that you should not over feed magnesium as the body needs it balanced alongside other minerals.

Brewer's Yeast is, I think, okay to feed long term. But again would probably look at what deficincies horse has first to ensure you are addressing unbalances.

My understanding is that magnesium does not compete with any other minerals and is safe to feet in high doses long term. I have been feeding it for 6 years now with no issues, as have a great number of barefooters. We see an effect in reducing footie horses, especially in spring and autumn.

If you have a pointer to a report on the heart arrythmia, I'd love to read it.

I cannot imagine why anyone would consider it unsafe to fee Brewers Yeast long term.
 
We feed magnesium to my sister's tb long term as it makes a huge difference to his behaviour. Without it he can be very riggy and biostrous, on it he's so much calmer and happier.
 
Examples below the only site I found saying that magesium is safe to feed in excess seemed to be selling magnesium supplements.

Magnesium

Foals fed a purified diet containing magnesium at 8 mg/kg (3.6 mg/lb) exhibited hypomagnesemia, nervousness, muscular tremors, and ataxia followed by collapse, with increased respiratory rates, sweating, convulsive paddling, and death after a few weeks. However, most commonly used feeds contain magnesium well in excess of the 70–100 mg/kg dry ration currently recommended. Oversupplementation of this mineral is more likely. Though the effects of excessive magnesium intake in horses have not been determined, based on data from other species it may cause clinical signs of calcium deficiency.

Small trial group but raises some questions :
Conclusions so far

Magnesium needs to be used with great care as a calmer. Too much and you run the risk of sedation, too little and the bad behaviour will continue if not worsen because the brain is unbalanced. What is making this trickier is an increasing trend for feed companies to increase their magnesium levels – presumably in the hope that behavioural problems (not solved by their low starch diets) will miraculously go away. In fact they may be making behaviour worse for many horses.

It is clear that there needs to be a balance of the right nutrients for optimum brain function. Any deficiency (or oversupply) i.e. magnesium, B group vitamins, L-Tryptophan and most importantly calcium, will cause a chemical imbalance and behavioural problems WILL appear. If your horse is deficient in one nutrient, it will almost certainly be deficient in another. Therefore the approach needs to be "let’s get the complete balance right, give the brain exactly what it needs to function as nature intended but in the right amount and solve most behavioural problems".

Generally, a horse's common diet provides more than adequate amounts of magnesium, but nervous individuals could respond positively to additional supplementation. However, excess magnesium can interfere with calcium metabolism and reduce absorption, so it is important that the ratio of calcium to magnesium remains at 2.5:1.

Magnesium in the form of magic, long term. I will not go without makes my welsh mare so much more happy and concentrates on me Sewell when schooling with minimal freak outs :p
