Resumo: This experiment was carried out in the Água Limpa Farm, of the University of Brasília, aiming to estimate the level of selenium and its variation during the year in some cultivated pastures of the cerrados region (Andropogon gayanus var. bisquamulatus, Brachiaria decumbens and Brachiaria ruziziensis). On the other hand, it was determined the effects of the supplementation, through intramuscular applications, in 24 Bergamacia weaned lambs. Pastures samples were collected trying to simulate the animal grazing, at intervals of 84 days, and different chemical methods of determination of selenium were evaluated. The fluorometric method has the best response and the levels of the samples varied from 0.025 to 0.075 ppm. In relation to the lambs, difference in weight gains were not statistically significant (P>0.05). KEY-WORDS: Brazilian savannas (“cerrados”); sheep; selenium supplementation.

O presente experimento foi conduzido na Fazenda Água Limpa, da Universidade de Brasília, e teve como objetivos verificar os níveis estacionais de selênio encontrados nas pastagens de Andropogon gayanus var. bisquamulatus, Brachiaria decunbens e Brachiaria ruziziensis e avaliar os efeitos da suplementação de selênio por via intramuscular em 24 ovinos desmamados da raça Bergamácia. Foram efetuadas quatro coletas de forragem procurando imitar o pastejo dos animais e testados os métodos químicos para análise de selênio. O método fluorométrico foi o mais adequado e determinaram-se os níveis que variaram entre 0,025 e 0,075 ppm para as pastagens estudadas. Com relação aos cordeiros, não se observou efeito significativo para o ganho de peso dos cordeiros (P>0,05) com as injeções via subcutânea de selênio.
