Where are the mineral smart people? I have a question.
We usually give free choice salt blocks to our herd. They are Trace Mineral with Selenium. Our area soil is selenium deficient.
Last calving we had a few problem heifers and our Vet suggested putting out free choice molasses/mineral tubs like 2:1 or 3:1.
Here comes my question. The label on these tubs warns not to feed these tubs together with other feeds/minerals/salts which contain selenium.
First of all, how would one even measure selenium intake when it's free choice and lickable.
And second what is a number guideline of how much an adult cow can take on selenium and what is too much?
What are the negative side effects of giving too much selenium?
It's no big deal to switch to different salt without selenium, but I just wondered after seeing the warning on the label.
