We have never fed the Purina product but I suspect the Mix 30 is cheaper. The last we bought was $260/ton.

It might be cheaper but what do you get? Mix30 has a Selenium content of .147 ppm whereas Sup-R-Lix is 1.0 ppm. In a Selenium deficient area, the difference is significant. Mix30 has a Manganese content of 12.7 ppm whereas Sup-R-Lix is 38 ppm. Potassium is .773% vs 2.1% with Purina. In addition. Mix 30 is 57% moisture compared to Purina's 29% moisture. There is no Vitamin A or D in Mix30 either.
Don't know about the Purina moisture level as their website doesn't disclose this information. However, almost all the protein comes from urea, Mix-30 contains none but does contain some ammonium chloride.
The correct selenium level for the Purina product is .1 ppm not 1.00 ppm. The potassium for the Purina product will be high because it is molasses based and molasses is extremely high in potassium. Does this high level of potassium serve a good purpose???? You also have between 1.75% and 2.25% calcium in the Purina product and calcium is dirt cheap. There is no mention of Vitamin D or E on the Purina website whereas Mix-30 guarantees 22.6 IU/lb of Vitamin E. The Mix 30 should provide over twice as much energy as the Sup-R-Lix.
