This study demonstrated relevant transfer of bioactive compounds
from fresh sprouts to egg yolk, which simultaneously
reduced the egg cholesterol.The results herein obtained sustain
the possibility to enrich egg not only in LCPUFAn-3 but also
in isoflavones, antioxidant and vitamins. The fatty acids and
phytoestrogens present in both alfalfa and flax sprouts could
be the main responsible for the effect recorded by us, whereas
the phytosterols seem to have a lower influence. These positive
results encourage further studies to evaluate the effects
of different supplementation levels and strategies (e.g., inclusion
of lyophilised sprouts in the hen’s diet).
