Its probably not that you don't have enough copper in the diet, it's that the copper is being tied up by antagonists and the animal can't absorb it resulting in a deficiency. There are tons of threads out there on this. You probably don't need a custom. The two most popular quality minerals on this site are probably purina availa 4 & vitaferm conceptaid. Side note selenium is regulated by the government, so a lot of times more isn't possible. If you need more selenium as well you will want an organic source of selenium rather than an inorganic one.ClinchValley said:Do I need to get a custom mineral mixed to achieve the needed levels of copper and selenium?
Do y'all think extra copper and selenium intake could combat the water issue? Water is provided via Richie water tanks. Shouldn't the sulphur evap from the water as it runs into the tank? Probably not near enough to make any difference is my thinking.
I think Se is regulated to 100-120ppm, you'd at least want a mineral with that much in it, if that's still not enough you could give a selenium injection, probably a month before calving would be a good time.
Copper oxide is virtually useless as far as absorption, but copper sulfate does have a decent bioavailablility as most sulfates do, and it's also readily available.. I usually look for a mineral with 2500ppm copper
