Abstract: Maternal Zn deficiency has been suggested as the contributing factor for all congenital malformations during pregnancy particularly in diabetes. Maternal Zn-supplementation, therefore, was suggested as one possible nutrition intervention during pregnancy to improve its outcome. But a number of trials with Zn-supplementation are not consistent and discourage the use of excessive Zn-supplementation during pregnancy. Instead a multivitamin/ mineral supplement to them has been suggested to reduce its complication. Accordingly, the poultry egg was modified for trace elements, vitamin-E and omega-3 fatty acids so as to use it as a dietary supplement for diabetics to reduce their complications during the pregnancy. The results showed that NIDDM induced rats fed either on 40 or 80 mg Zn/kg diet delivered less number of pups/litter and their body weight was higher at birth as compared to control group fed 20 mg Zn/kg diet. During the weaning period, some abnormalities characterized by restricted movements of the hind legs, curl toes of limbs, eye opening problems, less hair on the body and more head to body ratio were observed. Whereas number of pups delivered per litter were more with higher body weights without abnormalities in the pups in NIDDM groups fed egg mixed diet. Further Zn, Cu and Mg concentrations were significantly less in the liver, hair and abdominal muscles in pups in NIDDM groups but their concentrations were restored approaching closer to control in pups in groups fed egg mixed diet estimated on 18th day of weaning period. The excretion of these trace elements increased in the urine of dams fed Zn supplemented diet but decreased in the dams fed egg mixed diet on 15th day of their suckling period. The data suggest that if these modified eggs are included in the regular diet during pregnancy, they may protect the neonates in womb against the damaging effect of imbalances of physiologically important nutrients due to diabetes or environmental contamination.
