NUTRITIVE-VALUE OF EGGS IN LOW AND HIGH CHOLESTEROL GROUPS OF JAPANESE-QUAIL - FATTY-ACIDS, FAT-SOLUBLE VITAMINS, AMINO-ACIDS

We evaluated the content of vitamins retinol (as retinol acetate), cho lecalcipherol and tocopherol, the content of fatty acids and amino aci ds in eggs of two groups of Japanese quail selected for low (LC) and h igh (HC) yolk cholesterol concentration. 1. Content of retinol (as ret inol acetate) was in LC-group 228.7 and in HC-group 294.5 mu g/100 g w et yolk (mean value) (P less than or equal to 0.05). 2. Content of cho lecalcipherol was in LC-group 1.341 and in HC-group 1.667 mu g/100 g w et yolk (mean value). 3. Content of tocopherol was in LC-group 2.89 mg and in HC-group 3.93 mg/100 g wet yolk (mean value). 4. By analysing yolk fatty acids we found in LC-group 11.2% myristic acid but none was found in HC-group. We found in HC-group 8.12% stearic acids but none was found in LC-group. The content of oleic acids was by 12% higher in LC-group. In HC-group the content of unsaturated fatty acids with lon ger chain C-22-C-30 (10.3%) was twice as high as in LC-group (4.5%).
