Does Azadirachita indica leaves, Stylosanthes fruticosa and Dolichus lablab substitute conventional concentrate mixture: Evidence from the sheep feeding trial
Conventional concentrate protein supplements are available at a very high price in developing countries, and this has led to the use of alternative sources such as forage legumes and multi-purpose tropical trees to improve the nitrogen deficiency in roughage feeds.

| description | Conventional concentrate protein supplements are available at a very high price in developing countries, and this has led to the use of alternative sources such as forage legumes and multi-purpose tropical trees to improve the nitrogen deficiency in roughage feeds. Consequently, this study was planned to analyze the basis that Stylosanthes fruticosa (SF), Dolichus lablab (DL), and Neem tree leaves (NL) substitute the feeding value of commercial concentrate mixture (CM) for growing lambs. Twenty-eight-yearling intact male Gumuz sheep with an initial mean body weight of 19.42 ± 3.51 kg (means ± SD) were allotted through a randomized complete block design to 4 treatments and 7 replicates. Treatments were Rhodes grass hay fed ad libitum to all treatments plus 300 g CM (T1), 385 g NL (T2), 435 g SF (T3), and 355 g DL (T4). The total dry matter (DM), organic matter (OM), NDF, ADF, and ADL intake of sheep supplemented with SF was higher (P < 0.01) than in other treatments. Supplementation of CM had higher (P < 0.01) crude protein digestibility than NL, SF, and DL. Body weight change and average daily gain were higher (P < 0.05) on diets based on supplementation of CM than on those based on DL and SF but did not differ from NL. The total edible offal showed a significant difference (P < 0.01) among treatments; a higher value was observed for the group supplemented with CM. Liver and total fat differed significantly (P < 0.01) among treatments. The partial budget analysis result indicates that the NL, SL, and DL supplements are more profitable than CM. Because of their biological and economic feasibility, NL, and DL can be replaced CM and be employed in feeding systems depending on their availability and relative cost. |
