    abstract = {The study aimed to determine the effects
of <i>in ovo</i> injection of nanocurcumin and vitamin E on the
immunity and growth performance of broilers. Six
hundred eggs containing live 17.5 day-old embryos were
assigned to six treatments. Four groups were inoculated as
follows: 0.05 mL corn oil containing 0.015, 0.030 mL/egg
nanocurcumin, 0.037 and 0.074 IU/egg vitamin E,
whereas two groups remained as un-injected controls and
oil-injected sham. The chicks were reared under heat
stress. The cellular immunity was significantly increased
(p<0.05) by <i>in ovo</i> administration of vitamin E 0.037 and
decreased by <i>in ovo</i> injection of vitamin E 0.074 at 8 and
12 h after injection as compared to control. Body weight
gain 1-10 day was significantly decreased (p<0.01)
by <i>in ovo<i> injection of nanocurcumin 0.015 and
vitamin E 0.074, however, it and feed intake 25-42 day
was significantly increased (p<0.05) by <i>in ovo</i> injection of
nanocurcumin 0.030 without affecting feed conversion
ratio. This study evidenced the <i>in ovo</i> administration of
nanocurcumin 0.030 improved growth performance
during 1-42 days, however, decreased the hatchability.
Solutions did not have a significant effect on humoral
immunity but cellular immunity was improved by <i>in ovo</i>
injection of vitamin E 0.037.}
