all over Iowa | You most likely don't need that level of phosphorus, which is the most expensive major mineral. We are using a mineral with 4% phos.
Also be sure to seperate additive costs from the mineral costs. Fly control, antibiotics, probiotics, etc all raise the cost significantly per bag, but are not part of the mineral nutrition cost.
Formulating a free choice mineral that will hit the nutritional targets and provide predictable intake is hard to do with a cheap mineral. $20/bag is a dime or less per cow per day. $36 a year for a cows mineral, trace mineral, and vitamin nutrition isnt that much compared to other annual costs. If you found mineral that cost half as much you'd save $18 per cow per year and I'd have real questions about the quality and digistabilty of the ingredients. | |

What to use for minerals?Seems to me that well over 20 bucks a bag is plenty.
