Vitarnin A levels of egg yolk from hens fed diets supplemented with vitamin A increased slowly up to Week 4, while the values rapidly increased thereafter. The highest value(360% of initial value) was observed at Week 8 in birds fed 64,000 IU of vitamin A/kg diet. On the other hand, the contents of vitamin E in egg yolk rapidly increased in the first 2 weeks of the experiment and then stabilized up to Week 8. However, the efficiency of egg transfer decreased(P<0.05) as dietary vitamins A and E levels increased. It took at least 4 weeks for the increased levels of vitamin A and E in eggs from hens fed diets supplemented with each vitamin to recover the normal levels. Vitamin E levels of egg yolk in hens fed the vitamin A supplemented diets decreased as dietary vitamin A level increased (P<0.05). On the other hand, a slightly reduced levels of vitamin A levels of egg yolks from hens fed the vitamin E supplemented diet for 4 weeks of experiment was recovered back to control level at Week 8(P<0.05). Supplemental vitamin A markedly decreased the yolk deposition of vitamin F when two vitamins were supplemented simultaneously. The yolk deposition of vitamin A decreased as high level of vitamin B was supplemented, suggesting an antagonistic interactions between the two vitamins.
