We investigated the effect of different kinds of dietary added fat on the fatty acid composition, cholesterol content and quality of hens‘ eggs. The Haugh units, breaking strength, shell thickness and yolk color were not significant difference among the groups. Dietary fat notably altered the polyunsaturated fatty acid composition and cholesterol content in the egg yolk. The n-6 fatty acid of egg yolk was highest in the corn oil fed group with 31.61%, and this tended to decrease in the order of the tallow, linseed oil and fish oil fed groups(p<0.05). The n-3 fatty acid of egg yolk tended to increase in the linseed oil and fish oil fed groups as 9.74% and 5.16%, respectively(p<0.05). Theses alterations in the yolk fatty acid composition resulted in a reduced cholesterol content of the eggs. The ranges of cholesterol content showed values of 15.98-18.37 mg/g of yolk or 227-261 mg/60g of egg, respectively(p<0.05). The cholesterol content of egg yolk was highest in the tallow fed group, and this tended to be reduced in the order of the fish oil, linseed oil and corn oil fed groups(p<0.05). The reduction of the egg yolk cholesterol content in the other groups compared to the tallow group was significantly different, i.e., 13.01% in the fish oil group, 11.49% in the linseed oil group and 6.91% in the corn oil group, respectively(p<0.05). This result suggests that it is possible to reduce the cholesterol content or to increase the n-6 and n-3 polyunsaturated fatty acids in eggs by manipulation of the dietary added fats.
