Hen Day (H-D) and Hen-Housed (H-H) egg production for 135 day period compared in two quail strains and their reciprocal crosses in two separate trails. At the first trail in two hatches 180 Japanese quail (Coturnix japanese) and 180 Range quail (Coturnix ypisilophorus) were reared in two different spaces [litter with sawdust (250 x 200 x 230 cm) and one-tier cage (50 x 50 x 70 cm)]. The 130-day period production was measured from date of first egg for each female. Strain difference were not significant for H-D (p>0.05), but there were significant difference for H-H (p<0.01). Also H-D and H-H were significantly different by space of variations (p<0.01). Japanese quails with H-H 72.42 +/- 0.65% were significantly higher than Range quail with 62.68 +/- 1.07. At the second trail in two hatches 800 quails include four groups: 1--Japanese quails, 2--Range quails, 3--Hybrid 1 (R male x C female). 4--Hybrid 2 (C male x R female) were reared in four-tier cage from 28 days of age to experiment end. H-D and H-H of four groups were significantly different (p<0.01). Japanese quails with H-D 77.39 +/- 1.23% were the highest in four groups, but H-D between Japanese quail and H2 was not significantly different (p>0.05). H-D were not affected by hatch effects (p>0.05), but H-H at second hatch was significantly higher than first hatch. Egg weights were obtained with sample 35 eggs which randomly were selected at 70th, 115th and 175th days of age production for Japanese quails, hybrid 1, hybrid 2 and Range quails 11.16 +/- 0.16, 10.92 +/- 0.17, 10.61 +/- 0.11 and 11.06 +/- 0.12 g, respectively.
在两项独立试验中，比较了两个鹌鹑品系及其正反交组合在135天内的母鸡日产蛋量（H-D）和入舍母鸡产蛋量（H-H）。在第一次试验的两批孵化中，180只日本鹌鹑（日本鹌鹑）和180只草原鹌鹑（黄脚三趾鹑）在两个不同空间饲养[垫有锯末的地面（250×200×230厘米）和单层笼（50×50×70厘米）]。从每只母鸡的首个产蛋日起测量130天的产蛋量。品系间在母鸡日产蛋量方面差异不显著（p>0.05），但在入舍母鸡产蛋量方面存在显著差异（p<0.01）。此外，母鸡日产蛋量和入舍母鸡产蛋量在饲养空间上也存在显著差异（p<0.01）。日本鹌鹑的入舍母鸡产蛋量为72.42±0.65%，显著高于草原鹌鹑的62.68±1.07%。在第二次试验的两批孵化中，800只鹌鹑分为四组：1——日本鹌鹑，2——草原鹌鹑，3——杂交1（草原鹌鹑♂×日本鹌鹑♀），4——杂交2（日本鹌鹑♂×草原鹌鹑♀），从28日龄饲养至试验结束，饲养于四层笼中。四组的母鸡日产蛋量和入舍母鸡产蛋量存在显著差异（p<0.01）。日本鹌鹑的母鸡日产蛋量为77.39±1.23%，在四组中最高，但日本鹌鹑与杂交2之间的母鸡日产蛋量差异不显著（p>≥0.05）。母鸡日产蛋量不受孵化批次的影响（p>0.05），但第二次孵化的入舍母鸡产蛋量显著高于第一次孵化。在日本鹌鹑、杂交1、杂交2和草原鹌鹑产蛋的第70天、115天和175天，随机抽取35枚蛋称重，蛋重分别为11.16±0.16、10.92±0.17、1o.61±0.11和11.06±0.12克。
