Abstract
El objetivo de la investigación fue evaluar dos edades de codornices japónicas reproductoras de 12 y 32 semanas de edad, alimentadas con seis de niveles de calcio y fósforo disponible, 3.20 y 0.40 por ciento, Instituto de Investigación Científica Avícola (I.N.R.A. 1989), 2.50 y 0.35 por ciento National Research Council (N.R.C. 1994), 3.10 y 0.45 por ciento (Leeson y Summers 2005), 2,50 y 0.30 por ciento (Shim 2004), 3.15 y 0.41 por ciento (Lázaro et al. 2005) y 3.10 y 0.32 por ciento (Rostagno et al. 2017), sobre los parámetros productivos, calidad interna y externa de huevos, parámetros reproductivos, rendimiento de la progenie y la retribución económica. Se utilizaron 864 codornices hembras y 288 machos, divididos en doce tratamientos con cuatro repeticiones, suministrándoles el alimento en forma de harina y agua fresca “ad libitum”. Para el análisis estadístico se utilizó el diseño completamente al azar con un arreglo factorial de 2 x 6 y la prueba de comparación múltiple de Duncan. No se observaron diferencias significativas para el efecto de interacción de edad por recomendaciones de niveles de calcio y fósforo disponible en ninguno de los parámetros evaluados. Se encontraron diferencias significativas (p<0.05) a favor de las hembras adultas en el número de huevos incubables por semana, porcentaje de postura, masa de huevos y conversión alimenticia, mientras que las hembras jóvenes presentaron un mayor peso promedio del huevo incubable, bajo consumo de alimento, mejor índice de yema, mayor peso del albumen y de cáscara, mejor calidad interna de los huevos en unidades Haugh, mayor porcentaje de fertilidad, incubabilidad, nacimientos y menor mortalidad embrionaria temprana. En cuanto a las recomendaciones de calcio y fósforo disponible, se encontraron diferencias significativas (p<0.05) en el espesor de la cáscara cuando se utilizó la recomendación de Lázaro et al. (2005), en las unidades Haugh con la recomendación del I.N.R.A. (1989) y en la mortalidad embrionaria temprana con la recomendación del N.R.C. (1994). La mayor retribución económica para la producción de huevos incubables, fue observada en las codornices adultas alimentadas con la recomendación del N.R.C. (1994) y para la producción de cotupollos viables, en las codornices jóvenes alimentadas con la recomendación de Rostagno et al. (2017).
The objective of the research was to evaluate two ages of breeding Japanese quails of 12 and 32 weeks old, fed with six levels of calcium and available phosphorus, 3.20 and 0.40 percent (I.N.R.A. 1989), 2.50 and 0.35 percent (N.R.C. 1994), 3.10 and 0.45 percent (Leeson and Summers 2005), 2.50 and 0.30 percent (Shim 2004), 3.15 and 0.41 percent (Lázaro et al. 2005) and 3.10 and 0.32 percent (Rostagno et al. 2017), on productive parameters, internal and external quality of eggs, reproductive parameters, progeny performance and economic return. A total of 864 female and 288 male quails were divided into twelve treatments with four replicates, providing them with food in the form of flour and fresh water “ad libitum”. For statistical analysis, a completely randomized design with a 2 x 6 factorial arrangement and Duncan's multiple comparison test was used. No significant differences were observed for the interaction effect of age by recommendations for calcium and available phosphorus levels in none of the parameters evaluated. Significant differences (p<0.05) were found, where adult females showed a better response in the number of hatching eggs per week, laying percentage, egg mass and feed conversion, while young females presented a higher average hatching egg weight, lower feed consumption, better yolk index, higher albumen and shell weight, better internal egg quality measured by Haugh units, higher fertility percentage, hatchability, hatchability and lower early embryonic mortality. Regarding the recommendations for calcium and available phosphorus, significant differences (p<0.05) were found in shell thickness when using the recommendation of Lázaro et al (2005), in Haugh Units with the recommendation of the I.N.R.A. (1989) and in early embryonic mortality with the recommendation of the N.R.C. (1994). The highest economic return for the production of hatching eggs was observed in adult quails fed with the recommendation of the N.R.C. (1994) and for the production of viable baby quails in young quails fed with the recommendation of Rostagno et al. (2017).
