A composition for limiting feed supplement intake for ruminants is disclosed which comprises a chlorinated fat having a reacted chlorine content in an amount effective to limit intake or usually between about 0.2 and 7.0% by weight of said fat. The chlorinated fat can be incorporated into a feed supplement at a level effective to limit intake, preferably at a level exceeding 1.0% by weight, in addition to being employed with other intake limiters such as meat meal, diammonium phosphate, and ammonium sulfate in a feed supplement for intake control. The noted composition controls feed supplement intake by ruminants when added thereto permitting self-rationed feeding without waste.
