Q: I'm looking for some help in developing a mineral program for my cow herd and wondered what was best for our area? Specifically, if there is commercial off-the-shelf offerings that would be sufficient or if there should be a custom mix put together.
Thanks. -- B.T., Ash Grove, Mo.

Normally I feel there are few instances in which a "special" mineral mix would be necessary. Every feed company has a variety to choose from. Seldom do you need the high dollar mineral. Salt is the primary mineral they like and need for the sodium in it. I would want the mineral to have at least 20 percent to 25 percent salt in it. Phosphorus levels in the 6 percent range should be adequate if you're feeding decent hay or pasture. Phosphorus will also come from concentrate supplements like distillers grains.
The trace minerals should run 1,500 parts per million on copper, 3,500 ppm on zinc and 12 ppm on selenium. They may not be necessary but most dealers say they are in their supplements.
Finally, minerals often have other ingredients contained in them such as fly controls, antibiotics, mystery items to combat fescue toxicosis. The latter is usually not effective so I'd just buy a mineral for the true mineral ingredients.
