All horse owners need to know about the intake of this mineral.
All horses will need a certain amount of it. If the horse is on pasture with soil that contains normal levels then supplementation is not necessary and over supplementing will be very negative to the health and well being of the horse.
If the soil level is too low, or the horse is stabled without any supplementation – then the health of the horse again suffers and supplementation is necessary.
HOWEVER it is vital to have a blood test done before considering supplementing this mineral – for full details on whether you should give it to your horse, read our article on Selenium.
