Bottom Line: Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP.Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level.In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%).

ABSTRACT
The present work was conducted to examine the effects of dietary crude protein (CP) levels (18, 21 and 24%) on growth performance (Initial and final body weight, daily body weight gain, feed consumption, feed conversion and protein efficiency ratio) during 2-9 weeks of age and certain body measurements (body height, tibiotarsus length and tibiotarsus girth) at 9 weeks of age. A total of 30 African Black unsexed ostrich chicks were used in the present study in simple randomized design. The results of the present work indicated that initial and final live body weight, body weight gain, feed consumption, feed conversion of ostrich chicks were insignificantly affected by dietary protein level used. Protein efficiency ratio was high in the group of chicks fed diet contained 18% CP. Results obtained indicated that tibiotarsus girth was decreased (P≤0.01) with the increasing dietary protein level, where the highest value of tibiotarsus girth (18.38 cm) was observed in chicks fed 18% dietary protein level. Body height and tibiotarsus length were not significantly different. In conclusion, the results of the present study indicate that ostrich chicks (during 2-9 weeks of age) could grow on diets contain lower levels of CP (18%).

Mentions: The results of final live body weights, daily body weight gain, feed consumption, feed conversion ratio and protein efficiency ratio are presented in Figures 1, 2, 3, 4, 5 and 6. It is evident from the results found in Figures 1 and 2 that final live body weights and daily body weight gain of ostrich chicks were insignificantly affected by dietary protein levels used. Results indicated the occurrence of insignificant differences in the initial body weight among the different groups, a finding which give an idea about the accuracy in distributing chicks among the treated feeding groups without any bias.
