Abstract

Thirty Kambing Kacang does were divided into 9 groups and given the following treatments: Elephant grass ad lib. (A); Elephant grass ad lib. plus either 25% of ad lib. concentrate (B); 50% ad lib. concentrate (Q 75% ad lib. concentrate (D); ad lib. concentrate (E); 25% ad lib. leucaena (F); 50% ad lib. leucaena (G); 75% ad lib. leucaena (H) or ad lib. leucaena (J).
Liveweight change, dry matter intakes, feed conversion ratios and the proportions of each feed consumed were measured over a 12-week period.
Animals offered 100% elephant grass lost wei-ght (–19 g/day). Liveweight gains increased with increasing intakes of both leucaena and concentrate up to ad lib. intakes of each. The intake of elephant grass declined with increasing intakes of concentrate and leucaena. The maximum liveweight gains were 76 g/day with concentrate and 43 g/day with leucaena and the corresponding feed conversion ratios were 6.3 and 12.9
