Research has focused on the mineral nutrition of beef cattle in grazing and fed environments. Research has been conducted to determine the site and extent of magnesium absorption in ruminants along with developing feeding management strategies to reduce the incidence of grass tetan – a significant metabolic disease affecting beef cattle immediately after calving. Research has also been conducted to reduce the environmental effects of mineral excretion from cattle fed in confined animal-feeding operations.


Extension and Outreach programs have focused on mineral nutrition needs of grazing cattle.
