Body development of beef heifers grazing Italian ryegrass pasture (Lolium multiflorum Lam.) was evaluated. The animals received different alternatives of mineral supplement: associated or not to ionophore addition and the treatments were: 'Common salt': mineralization with sodium chloride; '40P salt': mineralization with mineral salt plus 40g of phosphorus per kilo of product; 40P salt + ionophore: mineralization with 40g of phosphorus plus 2000mg of lasalocid per kg of product. The values of crude protein, neutral detergent fiber and Ca and P of the apparently consumed forage, salt intake, body condition and body weight:height relation were similar (P>0.05) between animals receiving 'common salt', '40P salt' and '40P salt+ionophor'. For beef heifers grazing ryegrass pasture without intake restriction, the lasalocid associated to mineral salt provides a greater body weight at twelve months age and a positive financial.
