Too many supplements?

[teabiscuit]

does anyone know the recommended daily amount of selenium and vit E for horses?

Would feeding equivite, pink powder and selenium,vit.E and lysene supplements together overdose my horse on selenium and vit.E?

thanks in advance

All I can find (in a Sarah Pilliner book - Horse Nutirion and feeding) is Selenium 0.2mg per kg of diet (2.5mg per day for 16hh 500kg horse) and for Vitamin E the supplement should provide 100mg per kg.

thanks Haniki,
thats great.

I found one recommendation for 1mg in supplement form on the internet, there doesn't seem to be a lot of information about it

so thanks again

Selenium is one mineral that y ou can overdose a horse on. It is poisonous in high quantities.

It is also a tricky one because selenium is found in grass. Some areas have higher quantities of selenium in the soil, and hence the grazing than others. Most areas of the UK are not deficientin selenium.

it also depends upon whatthe horse is being fed. High cerial diets (feeding straights) can mean the diet is lacking in selenium and vitamin e.

if you are feeding more than 1/4 a pint of oil a day then you need to suplement selenium because the oil interferes with the horses absorbtion of vitamin E.

Selenium fed to horses to aid muscle problems. The dose on the pack is the recomended guide to the daily amount. However, you are quite correct to be aware of all sources of selenium in your horses diet. As with most things, the RDA and the dangerous dose are probably very different. There is usualy a large margin of error with these things.

The best course of action, to put your mind at is to get your vet to run a blood test for selenium levels.

So, in answer to your question... the safe dose would depend upon the size and weight of the horse, the other sorces of selenium in the diet, the dietitself, and any underlying medical conditions!

Do you know that you need to supplement? I only ask because you can over do selenium and it is often ingested naturally through plants found in grazing. There are some areas in the UK (particularly in Scotland) where selenium is deficient but ordinarily you shouldnt need to top up.

Ed. Sorry Yorkshire Lass, I seem to have been formulating a similar post without updating my screen first!
