Abstract	This experiment was conducted to evaluate the effect of protein salts supplementation on beef steers performance grazing deferred native pasture (DNP). The supplements evaluated were: protein salt with urea (SPU); protein salt with starea (SPA); protein salt with starea plus yeast (SPAL) and mineral salt (SM). The supplements were formulated to achieve a minimal ratio between ruminal degradable protein intake to digestible organic matter intake of 11 %. During the 118 days of experiment, 8 paddocks with 7,5 ha were utilized, each one with 8 steers, averaging 264 kg of weight and 18 months old, in a completely randomized design. The average composition of DNP was 6,8 % CP, 73,3 % NDF and 42,5 % OMIVD, and significative differences weren’t detected among treatments (p>0,05). The average daily weight gain (DWG) of animals supplemented with protein salt with starea plus yeast was higher than the animals feed mineral salt (0,287 vs 0,019 kg) (p<0,05), and DWG diferences weren’t detected among animals feed protein salt with urea or starea (0,159 vs 0,124 kg) (p>0,05). The average daily intake of protein supplements was higher than the mineral supplement (0,407 vs 0,038 kg) (p<0,05). The addition of live yeast to the protein salt formulated with starea resulted in better performance of steers grazing deferred native pasture. __________________________ 2 Master of Science dissertation in Animal Science – Faculdade de Agronomia, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, (79p.).
