Experiment was conducted on two hen lines according to egg type marked as SH-OL and SH-ML. The feed mixtures were enriched for folic acid. The content of folic acid was estimated by chemical analysis at 0.5 mg per kg in control feed mixture (CFM), at 1.5 mg per kg in first experimental group (FM E1) and at 3.5 mg per kg of feed mixture in the second experimental group (FM E2). Analysis of eggs showed higher content of folic acid in the experimental group E1 (0.06 – 0.11 mg per kg of egg melange), the highest content was in the experimental group E2 (0.10-0.16 mg per kg of egg melange) in comparison with control (0.05 mg per kg of egg melange). The highest content of folic acid was found in mother line (SH-ML) eggs in the E2 group where the repeated analysis showed values of 0.11 and 0.16 mg of folic acid/kg melange. In father line (SH-OL) in the E2 group we found 0.10 and 0.11 mg per kg content of folic acid. The results show that in the E2 group the content of folic acid in both lines was more than twice higher compared to control. Therefore, it is possible to use the folic acid- enriched hen eggs as health beneficial food for human nutrition.
