Grãos de destilaria desidratados de sorgo com solúveis (DDGS-S) não têm sido utilizados como suplemento em dietas de crescimento e terminação de cordeiros em condições de pastejo no verão. Postulamos que o desempenho de cordeiros pós-desmame em Paspalum notatum (PN) INIA Sepé suplementado com uma ração energético-protéica (grão de sorgo e farelo de soja) não é reduzido pela inclusão de 40 % DDGS-S. Em um delineamento experimental inteiramente casualizado com três tratamentos e duas repetições cada (n = 14 cada um), avaliamos 42 cordeiros Merino Dohne (130 ± 7,6 dias de idade, 32 ± 2,4 kg de peso corporal -PC- e 2,2 ± 0,2 escore de condição corporal) no verão (84 dias). Todos os cordeiros foram alimentados com PN INIA Sepé e dois tratamentos suplementados diariamente (1,7 % do PC). Os tratamentos foram: PN (sem suplementação); SGSM (70 % grão de sorgo, 30 % farelo de soja) e DDGS (45 % grão de sorgo, 40 % DDGS-S e 15 % farelo de soja). Cordeiros suplementados tiveram maior (P<0.0001) ganho de peso corporal, peso corporal final e crescimento de lã (140 e 126 g/a/d; 43,5 e 42,4 kg; 1814 e 1892 µg/cm2/d para DDGS e SGSM, respectivamente) do que cordeiros controle (40 g/a/d; 35,5 kg; 1353 µg/cm2/d) (P<0.0001), sem diferenças entre os suplementados. A infestação por nematóides gastrointestinais foi afetada pelos tratamentos no dia 69, animais suplementados tiveram uma infestação menor do que os cordeiros controle (P=0.0024). A inclusão de DDGS-S no suplemento não reduziu o desempenho produtivo dos cordeiros quando a concentração de proteína bruta e energia desta permaneceu constante.
