The relative acceptability by African Hair sheep of 5 provenances of Gliricidia sepium was evaluated in a double Latin square (3 x 3) design with 14 day periods. The treatments were basal diets consisting of only the fresh gliricidia foliage (leaves and petioles)(M), the gliricidia together with sugar cane tops (MC) or gliricidia, sugar cane tops and a molasses-urea (10% urea) block (MCB). In each treatment the sheep had access to foliage from each of the 5 provenances of gliricidia (given in separate compartments of the feed trough). All diet components were offered ad libitum. Intakes of all provenances were high (exceeding 4 kg dry matter/100 kg liveweight/day) and not affected by the nature of the basal diet. The most readily accepted provenance was a local selection from Colombia (1.74 kg DM/100 kg liveweight/day), the relative intake of the other four provenances being: (Colombia = 100), Nicaragua 58-62, Nigeria 53-59, Guatemala125 54-56, Guatemala124 42-47. Although the differences in acceptability among provenances were significant, the intake of the least palatable was above the level considered to be optimum when tree foliages are used to supplement a fibrous low-N basal feed.
