PI-7 (2011) The Effect of MIN-AD Particle Size on Mg Bioavailability
This bulletin summarizes a research trial evaluating the impact of particle size of MIN-AD on serum Mg levels in dairy cows.  MIN-AD’s Fine, Standard, and Granular products were used in the study.  As expected, there was a trend for the smaller particle size products to produce higher serum Mg levels, but the differences were not statistically significant.

PI-8 (2011) Effect of Palatability on Free-Choice Mineral Intake of High Magnesium Minerals Made With Either Magnesium Oxide or MIN-AD by Beef Cows
This bulletin summarizes two years of research evaluating the intake of free-choice minerals by beef cows with either MgO or MIN-AD as the major source of Mg. In both years, intake of the mineral using MIN-AD as the primary source of Mg was considerably higher than the mineral with MgO as the source of Mg. In addition, intake of the high Mg mineral (10% Mg) with MIN-AD as the primary source of Mg was slightly higher than a low Mg (1.9% Mg) mineral with MgO as the source of Mg.

D-7 (2009) Impact of MIN-AD on Blood Levels of Magnesium and Calcium During the Transition Period
Low levels of Mg in the blood of dairy cattle during the transition period are often a problem contributing to milk fever. A switch-back trial was carried out on a large commercial dairy to determine the efficacy of MIN-AD as the sole source of supplemental Mg. Replacement of a supplement comprising MgO, limestone, and MIN-AD with just MIN-AD resulted in similar serum levels of Mg and Ca. Serum Mg levels are related to dietary intake and biovailability.
