Summary This study carried out to investigate the effects of intra‐yolk‐sac injection ( IYSI ) of some solutions including 1 ml of distilled water, dextrose 20% and albumin 20% on hatch percentage, performance traits, jejunum morphology, glycogen content of liver and breast and serum metabolites in broilers (Ross 308). Fertile eggs were injected into the yolk sac at day 8 of incubation period. Results showed that hatchability, absolute body weight ( BW ), feed intake ( FI ) and feed conversion ratio ( FCR ) at day 7 and 14 of growing period were not different among treatments, but in comparison with control group, BW and FCR were numerally better by IYSI of albumin. In addition, IYSI of albumin increased jejunum villus height at hatch day, but crypt depth was not affected by any injection treatments. Also, the glycogen concentrations of liver and pectoral muscle in albumin injected group were significantly higher than control at hatch and 7th day respectively. At hatch day, serum glucose and cholesterol concentrations were, respectively, maximum and minimum statistically by IYSI of albumin which continued numerally up to 7th day of rearing period. Furthermore, liver glycogen and serum glucose concentrations were directly correlated on the day of hatch. In conclusion, the IYSI of albumin could increase performance traits, jejunum villus height, liver and breast glycogen and serum glucose in broiler chicks.
