摘要

In the mixed crop-livestock farming system of Ethiopia where crop residues are the major feed resources and concentrate supplement feeds are not common, home-grown legume protein sources can help to minimise the feed problem. A 69-day feeding experiment on sheep was conducted to evaluate the potential of sweet blue lupin (Lupinus angustifolius L.) cultivar Sanabor seed as a substitute for commercial concentrate supplement. Thirty yearling male intact Washera sheep with initial body weight of 21 ± 1.38 kg (mean ± SD) were used. The design was a randomised complete block design with six replications. The five experimental supplement feeds were 453 g concentrate (T1), 342 g concentrate + 74 g lupin seed (T2), 228 g concentrate + 147 g lupin seed (T3), 116 g concentrate + 219 g lupin seed (T4) and 290 g lupin seed (T5) in dry matter basis to supplement around 100 g crude protein per day per animal. There were significant differences (P < 0.05) in total dry matter, crude protein, ash and organic matter intakes among treatments. The average daily body weight gain for T1, T2, T3, T4 and T5 was 91, 79, 79, 87 and 74 g/day, respectively, and this difference was not significant (P > 0.05). It was concluded that blue lupin seed has a potential to substitute the commercial concentrate supplement feed in Ethiopia.
