Supplementation of Dried <i>Khat</i> ( <i>Catha Edulis</i> ) Leftover with Concentrate Mixture on Productive Performance of Bati Goat at Kallu District, Amhara Region Ethiopia

The study was conducted to evaluate the effect of supplementation dried khat (catha edulis) leftover with concentrate mix on feed intake. Twenty five (25) yearlings Bati goats with an average live weight of 17.79 ± 0.83kg (mean ± SD) were grouped in to five blocks of five animals based on their initial body weight and the treatment diets were randomly assigned to the animals with in a block using RCBD. The experiment consisted of 90 days of feeding trial followed by 7 days digestibility trial. The number of supplements offered was 303.6 g/day/head on dry matter basis, at rations were formulated in iso-nitrogenous to meet the daily CP requirements of goats. All goats fed grass hay adlibitum and supplemented on concentrates mix with khat leftover meal at a ratio of 0%KLM, 10%KLM, 20%KLM, 30%KLM, and 40%KLM on DM -basis. The result showed that inclusion of KLM to some extent significantly decreased the intake of TDM (717.4 -683.8 g/d) and CP (90.9 -84.96 g/d). Apparent digestibility of DM, OM and CP was significantly (P < 0.05) decreased with increasing the level KLM. The BWC, FCE and ADG was lower 40%KLM than other tratment. Among supplement (0%KLM-30%KLM) was comparable potential to supply nutrients for improving the weight gains of goat. Relatively the highest net return and change in net return were obtained in increased (619 -653.68 ETB) with increasing the level of KLM (10%KLM-30%KLM). Gennerally, inclusion of khat leafover meal up to 30% could be obtained better body weight gain. From the perspective of the economic level (30% KLM with 70% CM) was recommended for better animal performance and more economically visible for producers.
