The purpose of the present study was to determine the effects of diets containing 3% palmitic acid (Diet PA), oleic acid (Diet OA), or linoleic acid (Diet LA) on the shell quality of eggs of Japanese quail. Each diet was fed to 10 hens maintained individually in wire quail laying cages. There was no difference (P greater than .05) in feed consumption between hens fed Diets OA and LA, but hens of both groups consumed less (P less than .05) feed than those fed Diet PA. Egg weight, shell weight, and thickness of shell plus membrane were not influenced by dietary treatment (P greater than .05). However, specific gravity of eggs from hens fed Diet OA was significantly higher (P less than .05) than that of eggs from those fed either Diet PA or Diet LA. Comparison of these data with hatchability data obtained in a previous experiment conducted under similar conditions suggests that the differences in hatchability would not be explained by differences in eggshell quality.
本研究的目的是确定含有3%棕榈酸（PA日粮）、油酸（OA日粮）或亚油酸（LA日粮）的日粮对日本鹌鹑蛋蛋壳质量的影响。每种日粮饲喂10只单独饲养在鹌鹑产蛋笼中的母鸡。饲喂OA日粮和LA日粮的母鸡之间采食量没有差异（P大于0.05），但这两组母鸡的采食量均低于饲喂PA日粮的母鸡（P小于0.05）。蛋重、蛋壳重量以及蛋壳加内膜的厚度不受日粮处理的影响（P大于0.05）。然而，饲喂OA日粮的母鸡所产蛋的比重显著高于饲喂PA日粮或LA日粮的母鸡所产蛋（P小于0.05）。将这些数据与在类似条件下进行的先前实验中获得的孵化率数据进行比较表明，孵化率的差异不能用蛋壳质量的差异来解释。
