The objective of this study was to assess the carcass characteristics of two goat breed types under different durations of feedlot management. Forty eight yearling intact male Borana (n=24) and Arsi-Bale (n=24) goats were used in a 2 x 3 factorial arrangement, the factors being breed-type (Borana and Arsi-bale) and feeding days (90, 120 and 150). The goats were slaughtered after 18 hours fasting to evaluate the various carcass traits. The carcasses were separated into leg, lion, rack, shoulder and neck and breast and shank primal cuts. The Borana goats possessed heavier live weight, empty body weight, carcass weight and length than the Arsi-Bale goats in the feedlot environment. Dressing percentage varied from 41.0 to 45.9% for both goat breed types. Borana had greater rib eye area than Arsi-Bale goats for 120 (42.9±3.99) and 150 (47.3±1.28) feeding days. Back fat thickness was higher for both breed-types for 150 days feedlot feeding. The highest bone proportion was 30.9% for Arsi-Bale goats while the lowest was 25.7% for Borana goats. The percentage of rack fat of Borana was higher than for the Arsi-Bale goats.
