treatment 1 (T1), elephant grass (EG; Pennisetum purpureum as T2), guinea grass (GG; Panicum maximum as
T3) and bermuda grass (BG; Cynodon dactylon as T4) supplemented with a similar amount of concentrate
mixture (CM; wheat bran (WB) and Noug seed cake (NSC) at 67:33 ratio) on performance and economy of
fattening of Blackhead Ogaden sheep. The study consisted of a feeding and digestibility trials of 90 and 7
days long, respectively. Twenty-four intact yearling Blackhead Ogaden sheep with an initial body weight (BW)
of 15.83±0.04 kg (mean±SD) were used in a randomized complete block design based on their initial BW
with four treatments and six replications. All animals received 300 g dry matter (DM) of CM. Nutrient
concentration of RG, EG, GG, BG, NSC and WB were 5.5, 8.8, 7.6, 7.9, 24.3 and 14.0% crude protein (CP), and
83.3, 74.5, 75.4, 81.5, 39.0 and 45% neutral detergent fiber, respectively on DM basis. Intake of DM was
696, 700, 719 and 716 g/day (SEM = 0.004) for T1, T2, T3 and T4, respectively and was lowest for T1 and
highest for T3. The CP intake was also lowest for T1 (89 g/day), and similar among the other 3 treatments
(99-103 g/day). Digestibility of CP and organic matter were highest for T2, intermediate for T3 and T4 and
lowest for T1. Average daily gain was in the order of T2 > T3 = T4 > T1 (27, 63, 50 and 45 g/day (SEM = 13.1)
for T1, T2, T3 and T4, respectively); whereas hot carcass weight did not significantly differ among treatments
(5.7, 6.4, 6.1 and 6.3 kg (SEM = 0.36) for T1, T2, T3 and T4, respectively). Total return, net income and
marginal rate of return were all in the order of T2 > T4 > T3 > T1. Therefore, based on biological performance
as well as economic return, sheep fed elephant grass perform better. However, variations in performance and
economic return among the four grass species needs to be taken cautiously as part of the difference might
have attributed to differences in the stage of maturity of the grasses up on harvest for feeding the lambs.M. AhmedG. AnimutG. HassenK. Abdimahad
