| description | This study, carried out in the University of the Llanos, aimed to determine the optimal level of metabolizable energy and protein quail (Coturnix japonica) in laying phase. We used 480 quails 10 weeks old and 94±10 g of initial weight, distributed in a completely randomized experimental design, 4x4 factorial arrangement, with four levels of metabolizable energy (2750, 2850, 2950 and 3050 kcal EM.kg1), and four levels of crude protein (17.5, 19.0, 20.5 and 22.0%), with three replicates and 10 birds. The trial lasted 24 weeks, during which water and food were supplied at will. The results were processed in the SAEG program (2007), subjected to analysis of variance and polynomial regression. The results showed no interaction between the levels of metabolizable energy and protein, which means the factors acted independently. Analyzing each factor, a quadratic influence (p <0.05) was observed on egg production. The egg production was increased (91%) to the level of 2750 kcal of EM.kg1 and 20.5% crude protein. These levels provided a feed conversion related dozen eggs/kg was of 0.338, the value of egg mass of 2.852 with 3050 kcal EM.kg-1 and 19% crude protein. The equations y = -0.0038x2 + 0.1456x - 0.5771, y = R2 = 75.7 -8E-05x2 + 0.4466x-533.05, R2 = 0.89, allow to estimate the requirements of crude protein (2791 kcal EM.kg-1) and metabolizable energy (19.16%) for egg production. |

Este trabajo, realizado en la Universidad de los Llanos (Villavicencio, Meta), tuvo como objetivo determinar el nivel óptimo de energía metabolizable y proteína para codornices (Coturnix coturnix japónica) en fase de postura. Fueron utilizadas 480 codornices de 10 semanas de edad y 94±10 g de peso inicial, distribuidas según un diseño experimental completamente al azar, en arreglo factorial de 4x4, cuatro niveles de energía metabolizable (2750, 2850, 2950 y 3050 kcal EM.kg-1) y cuatro niveles de proteína bruta (17,5, 19,0, 20,5 y 22,0%), con tres repeticiones y 10 aves. El ensayo tuvo una duración de 24 semanas, durante las cuales el agua y el alimento fueron suministrados a voluntad. Los resultados fueron procesados en el programa SAEG (2007) y sometidos a análisis de varianza y regresión polinomial. Los resultados no arrojaron interacción entre los niveles de energía metabolizable y proteína, es decir, los factores actuaron de modo independiente. Al analizar cada factor, estos influyeron de forma cuadrática (p&lt,0,05) sobre la producción de huevos. La postura se incrementó (91%) hasta el nivel de 2750 kcal de EM.kg-1 y de 20,5% de proteína bruta, estos mismos niveles proporcionaron una conversión alimenticia relacionada con docenas de huevo/kg de ración de 0,338, el valor de masa de huevo de 2,852 con 3050 kcal EM.kg-1 y 19% de proteína bruta (PB). El desarrollo de las ecuaciones y=-0,0038x2 + 0,1456x – 0,5771, R2 = 75,7 y y=-8E-05x2+0,4466x-533,05, R2 =0.89 permite estimar en 2791 kcal EM.kg-1 y 19,16% los requerimientos de energía metabolizable y de PB, respectivamente, para la producción de huevos.
