Effects of Supplementing Finger Millet (Eleucine coracana) Straw with Grass Pea (Lathyrus sativus L.) Hulls and Concentrate Mixture on Feed Intake, Digestibility and Body Weight Change in Washera Sheep
The productivity of sheep in Ethiopia is very low mainly due to a serious shortage of feedstuff. As a result, it is necessary to look for cheap locally available feedstuffs to sustain sheep production in the country. Non-conventional feeds like grass pea (Lathyrus sativus L.) hulls (GPH) could partly fill the gap in the feed supply, decrease competition for food between humans and animals and reduce feed cost. Therefore, this experiment was designed to evaluate effects of different proportions of grass pea hulls and concentrate mixture (CM) supplementation on feed intake, digestibility, and growth of Washera sheep fed finger millet straw (FMS) as a basal diet. Diets consisted FMS alone fed ad libitum (T1), 100% CM (T2), 30% GPH mixed with 70% CM (T3), 30% CM mixed with 70% GPH (T4), and 100% GPH (T5). For all treatments, FMS was fed ad libitum. Experimental sheep were arranged in a randomized complete block design and treatment feeds were assigned to the animals within a block. The results showed that FMS contained 5.5% CP and 68.9% NDF. there was reduction (p < 0.05) in DM intake, DM and CP digestibility and consequently depressed ADG in sheep. Partial budget analysis results showed that net return and change in net return were in the order of T3 > T2 > T4 > T5. Therefore, from biological point of view as well as based on partial budget analysis, T3 was found to be recommendable for smallholder sheep produc-ers.
