A preference study of fonio and rice straws was done for both untreated and urea-treated straws. Sixteen lambs were used to determine the preference. The experimental feeds were offered to the lambs for 10 days adaptation. Feed amounts consumed over specific times were measured during subsequent 3 days. Nitrogen content of untreated fonio straw was simimlar to that of untreated rice straw. Urea treatment of straws increased the nitrogen content but reduced intake. Untreated rice straw was the most preferred feed folIowedby untreated fonio straw and the urea-treated straws, in that order (P 0.05). The consumption of experimental feeds interacted significantly (P 0.05) with the time of coIlectionof data. Large amounts offeed were eaten, however, the low protein intake would limit the growth oflambs.
