The objective of this study was to evaluate the utilization effects of two native cacti named mandacaru (Cereus jamacaru DC.) and xiquexique [Pilosocereus gounellei (A. Weber ex K. Schum.) Bly ex Rowl.] associated with sabiá (Mimosa caesalpiniifolia Benth.) and flor de seda (Calotropis procera (Ait.) R.Br.) about the nutrient intake, daily weight gain, and feed conversion in sheep feedlot. Twenty Morada Nova male hair sheep with an average weight of 15.40, were allocated in a randomized block design, with four treatments and five replicates. The experimental treatments consisted of four diets (30% native cacti + 30% shrub hay + 40% concentrate, on dry matter basis): T1- xiquexique + sabiá hay; T2- xiquexique + flor de seda hay; T3- mandacaru + sabiá hay e T4- mandacaru + flor-de-seda hay. The concentrate consisted of 100.0% algaroba (Prosopis juliflora (Sw) DC) pods. No significant difference was observed for daily weight gain which averaged 88.77 g, and also for voluntary intakes of dry matter, organic matter, ether extract, total carbohydrates, nonfiber carbohydrates, total digestible nutrients and digestible energy in relation to g/day, %BW and g/kg0.75. Significant differences were observed for intake of water in g/day.
