An experiment was carried out to study the effect of urea lime mixture in concentrate containing different levels of cassava on performance of the ettawa grade goats through in-vivo experiment. Arandomized block design (RBD) consisted of four different rations and four replicates was used in this experiment. A total of 16 ettawa cross bred goats with initial body weight ranging from 12.4 -19 kg were aranged into 16 pens experiment. Four feed treatments were offered to four groups of four goats. The first treatment (A) was 50% elephant grass 50% concentrate (without cassava urea lime) as control diet, the second treatment (B) was 50% elephant grass 50% concentrate (without cassava, with 4% urea and 2% lime), the third treatment (C) was 50% elephant grass 50% concentrate (with 25% cassava, 4% urea and 2% lime), and the fourth treatment (D) was 50% elephant grass 50% concentrate (with 50% cassava, 4% urea and 2% lime). Ration was composed based on standard requirement of 15 kg body weight goat with 75 g daily weight gain. Results of this study showed that urea-lime was not significantly affect the consumption of dry matter (DM). Eenergy consumption in treatment C and D were significantly higher than the energy consumption in treatment A and B. Ttreatment D was significantly higher than other treatments because the consumption of DM tends higher in treatment D compared with other treatments. Feed Convertion Ratio (FCR) in treatment D was the least significant compared with other treatments. It showed that concentrate containing 4% urea, 2% lime and 50% cassava was the most efficient to use in ration. The utilization of 4% urea and 2% lime combine with 50% cassava could improve the ettawa grade goat’s growth and feed efficiency. Keyword: Urea-Lime, Cassava, Performance and Ettawa Grade Goats.
