Zusammenfassung:The ingestive behavior and displacement and forage searching patterns of female lambs in Pearl millet (Pennisetum glaucum (L.)) were evaluated when lambs were kept exclusively on Pearl millet pasture and on pearl millet pasture receiving supplement. The supplement used was a commercial ration given daily at 17h. The experimental design was completely randomized, with two area replicates. The animals that received supplement reduced the grazing time and increased the idling time. The intake, displacement and forage searching patterns were influenced by changing on pasture structure along the Pearl millet stage of development and were not modified by supplement supply. Key words: continuous stocking, feed strategies, Pennisetum glaucum. O comportamento ingestivo e os padroes de deslocamento e procura de forragem de cordeiras em pastagem de milheto (Pennisetum glaucum (L.) foram avaliados quando estas foram mantidas exclusivamente em pastagem ou em pastagem recebendo suplemento (racao comercial fornecida diariamente as 17h. O delineamento experimental foi inteiramente casualizado, com duas repeticoes de area. Os animais que receberam suplemento reduziram o tempo de pastejo e aumentaram o tempo destinado atras atividades. Os padroes de ingestao, deslocamento e procura de forragem foram alterados pelas mudancas na estrutura do pasto ao longo dos estadios de desenvolvimento do milheto e nao foram modificados pelo recebimento de suplemento. Palavras-chave: estrategias alimentares, lotacao continua, Pennisetum glaucum.
