Hi, I was wondering if anyone else has experimented with making their own selenium/vit e drench. The oral gel tubes are 40 servings and cost around $8. This is 23.2 mcg selenium and 200 IU of Vit E at a dose once a month with this being the only selenium available to goat. I have been buying a bottle of ionic selenium for around the same price and mixing it myself with vit E. There is apx 620 servings of selenium in each bottle of the ionic selenium. I buy my vit E from puritans pride for about $5.70 for 100 capsules of 400IU. That is 200 doses. Therefore 40 doses are costing me around $1.60. My question is the ionic selenium also has tiny amount of magnesium, chloride and sulfate. Do any of you see any drawbacks to making this concoction and giving it to my girls instead of the gel made for goats?
