ABSTRACT This study was carried out to determine the effect of different pre-incubation
storage
periods of hatching broiler chicken eggs on weight loss and embryonic development. A total of two hundred and forty (240) broiler chicken hatching egg collected for four different days (60 eggs per day) were used for the experiment (TJ, T2, T3, and T4) and each treatment were stored for 12,8,4 and 0 day respectively
to determine pre-incubation
storage weight loss. Three (3) eggs were collected from each treatment at interval of 6, 9, 12, 15 and 18 days of incubation
to determine
relative
embryonic
weight during
incubation. Data were subjected to one-way analysis of variance. The results revealed that there were significant (P<0.05) in the value of egg weight loss and percentage egg weight loss as the day of storage increased. It was also shown that egg stored for 8 days had the highest relative embryonic
weight compared to other treatment
groups at day 18 of
incubation. It could be concluded that storage of fertile broiler hatching eggs at 18°C should not exceed one week in other to avoid excessive loss of egg constituents such as the albumen contents which would be needed by the developing embryo for growth and development during incubation.
