200 lambs were used to study the effects of 2% bentonite, 2% limestone and 1% bentonite + 1% limestone on the feedlot performance of lambs rapidly switched from alfalfa hay to 8% alfalfa hay plus 92% concentrate diets. Lambs receiving 2% bentonite or 2% limestone showed a slight improvement in feedlot performance during the initial 21 days, but the benefit was not sustained in the remaining feeding period. Lambs fed 2% bentonite had higher (P.01) plasma Mg concentrations at day 59
