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 > .05) in feed consumption between hens fed Diets OA and LA, but hens of both groups consumed less (P < .05) feed than those fed Diet PA. Egg weight, shell weight, and thickness of shell plus membrane were not influenced by dietary treatment (P > .05). However, specific gravity of eggs from hens fed Diet OA was significantly higher (P < .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.
