【 摘 要 】

- The experiment was carried out to evaluate the use of Leucaena leucocephala and Cajanus cajan as protein sources, during the dry season for lambs grazing on buffel grass pastures. Nine experimental treatments resulting from the combination among three types of pasture (buffel grass, buffel grass+Cajanus cajan, and buffel grass+leucaena) and three stocking rates (4, 6 and 10 lambs/ ha) were tested. Eighteen paddocks (two replicates of pastures per treatment) of 0.5 ha were used. Sixty lambs with 19.4 kg live weight at the beginning of the experiment were allocated to pastures with water and mineral supplement offered ad libitum. Animal liveweight was recorded at 14 day-intervals after 16 hours of fasting. Lambs on the pasture of buffel grass+leucaena showed good performance with no variation in daily liveweight gain rate, when the stocking rate increased from 4 to 6 animals/ha. Buffel grass+Cajanus cajan pasture did not improve animal performance as compared to buffel grass pasture. It was concluded that leucaena, used as protein supplement, can improve the quality of buffel grass pastures.
