A tota1 of' six hundred and thirty (630') eggs were purchased from a local breeding farm. Alter collection the eggs were cleaned and stored at specific temperature (18 °C) and humidity (75%). Eggs were equally divided into six groups i.e. A, B, C, D, E. and F having 105 eggs in each group and each group was further subdivided into three replicates having 35 eggs each. They were stored upto 4th, 7th, 10th, 13th, 16th and 19th day, prior to incubation. After incubation the effect of six different storage periods was studied on the various traits i.e. fertility percentage, hatchability percentage, clear eggs and dead in shell.
Statistical analysis of the data revealed that no differences were observed amongst the groups in case of fertility (P> 0.05) but in case of hatchability there were differences (P<O.O1) among the groups. The results also showed differences (P<O.O1) in dead in shell and no differences were observed in clear eggs.
The overall results, showed that as the storage time increased the Fertility and hatchability percentage decreased. This decrease was significant only in case of hatchability. However results were opposite in case of clear eggs and dead in shell percentage. It was seen that as the storage time increased the clear eggs and dead in shell percentage also increased.
The overall result, showed that as the storage time increased the hatchability percent decreased.
CONCLUSION
By having overall view of the present study it is concluded that for getting best results, quil eggs should not be stored for a longer time. However, for achieving best results the eggs may be set for incubation after every 3rd or 4th day.
