Anyway --- I do know that my mineral program has helped us. We are fortunate that we have a local company (husband's employer!) that custom blends mineral.
The local extension used our herd to research SE and bled a % of our herd several times, increasing the SE in the mineral as they were tested until we got it to a level that our cattle had "normal" blood levels. We had been giving them MuSe shots prior to calving - prior to breeding & again in the fall at workup. Without it, our cattle had scruffy hair coats, longer than normal labors, poor breeding, few retained placentas. We went "cold turkey" and quit giving any shots - just the mineral. And our breeding program improved, hair coats good & ww up.
Then, a few years ago, I started noticing our cows weren't shedding their haircoat, had scruffy hair, had more late cycles & more opens. Slowly got worse. Finally, I pinpointed the problem to a new water source that had sulfa in it. We researched it and Sulfa inhibits the ability to obsorb/utilize SE & copper - so we adjusted our mineral - back to normal.
BTW - Robert has a great herd. You may have seen him & his herd on TV. Maybe he's on to something?? or maybe his herd could be EVEN BETTER. :banana:
I figure the extra WW and early breeding pays most, if not all the $27/year ($0.07/day)
