title: Effect of feeding Neem (Azadirachta indica) and Acacia (Acacia senegal) tree foliage on nutritional and carcass parameters in short-eared Somali goats.
abstract: The study was conducted to determine the effects of dried foliage of Acacia senegal and Neem (Azadirachta indica) tree supplementations on feed intake, nutrient digestibility, growth, and carcass parameters in short-eared Somali goats. Twenty male intact short-eared Somali goat yearlings with an average live weight of 16.2 ± 1.08 (Mean ± SD) were assigned to four treatment groups, which comprised a basal diet of hay alone (T1) and supplementation with the tree foliages. Supplements consisted Neem tree (T2), A. senegal (T3) and the mixture of the two (1:1 ratio; T4) dried foliages. The crude protein (CP) content of Neem tree foliage, A. senegal, and their mixture were 16.92, 17.5 and 17.01 % of dry matter (DM), respectively. Total DM intake and digestibility of DM and organic matter were significantly (P < 0.001) higher for the supplemented groups. CP digestibility was significantly higher (P < 0.01) for goats supplemented with Neem tree (72 %) and A. senegal (67 %). The final body weights were higher (P < 0.05) for the goats supplemented with A. Senegal. An average daily body weight (BW) gain was higher (P < 0.01) in supplemented groups. The hot carcass weight was higher in the group supplemented with A. senegal (8.3 kg) among the supplemented groups, all of which are higher than the control (4.9 kg). It is concluded that the supplementation with tree foliage, especially with A. senegal tree foliage, on grass hay encouraged a better utilization of nutrients and animal performance as compared to goats fed on a basal diet of grass hay only.
