RESUMO

The experiment have the objective of determine the ideal crude protein level for Japanese quail raised in the Distrito Federal, Brasil, in a commercial farm.The experiment was developed using 260 one day-old female japanese quail. The experimental delineation was entirely random with five repetitions and 13 quails for each experimental unit. The birds had been fed with experimental diets contend four levels of CP (18; 20; 22 and 24%) and a constant level of metabolizavel energy (2,950 Kcal EM/kg). The results (one to 42 days old) were final Weight 154,66g, feed conversion 4,39, feed intake 643,59g and weight gain 146,71g. There was no significant difference for the parameter moela. However, the parameter liver presented significant difference (p<0,05) in the 35th day; the parameter weight of the intestine revealed a significantly (p<0,05) different between the treatments in the 28 th day; the parameter length of the intestine was significantly (p<0,05) influenced in the 42 th day. In the performance analysis, a significant difference (p<0,05) was verified in the parameter ration consumption in the 14 th day. However, for the others performances was not verified a significant difference between the treatments (p>0,05). Diet with 18% of CP, supplemented with metionina and lisina is indicated to female japanese quail of 1 to 42 years old.
