Effect of the rearing stage on production and reproduction in laying Japanese quail (Coturnix coturnix japonica)
The aim of this study was to evaluate the productive performance of laying quails (Coturnix coturnix japonica). The study was carried out at the poultry farm of the La Molina National Agrarian University in Lima, Peru. In total, 1296 quail distributed in 96 females and 48 males of three ages (45, 52 and 59 days) with 130, 140 and 150 g of body weight, respectively, at the beginning of the laying were used. A random block design with a 32 factorial arrangement was used, taking as factors age and weight at the beginning of laying and as a block the weeks of laying (8, 11 and 17). The highest egg mass (10.72 ± 0.41 g/day/bird) was obtained when the quails started laying with 150 g of live weight.

El objetivo de la investigación fue evaluar el rendimiento productivo de codornices (Coturnix coturnix japonica) de postura. El estudio se realizó en la granja de aves de la Universidad Nacional Agraria La Molina en Lima, Perú. Se utilizaron 1296 codornices distribuidas en 96 hembras y 48 machos de tres edades (45, 52 y 59 días) con 130, 140 y 150 g de peso al inicio de la postura, respectivamente. Se empleó un diseño de bloques aleatorios con arreglo factorial 32 teniendo como factores edad y peso al inicio de postura y como bloque a las semanas de postura (8, 11 y 17). Las mejores conversiones alimenticias fueron de 3.67±0.36 y de 3.68±0.35, sin diferencias estadísticas entre ellas, y se obtuvieron cuando las aves iniciaron su postura con pesos de 130 y 140 g, respectivamente. La mayor masa de huevos (10.72±0.41 g/día/ave) se obtuvo cuando las aves iniciaron su postura con 150 g de peso vivo.
