Effect of adding different levels of celery seeds powder with or without supplementation of exogenous enzymes upon the cost of feed for egg production and the external and internal quality of quail eggs

الملخص EN

A total 250 quail females 120 days old were randomly divided in to ten dietary treatments (1: basal diet, 2: basal diet plus 0.10% exogenous enzymes, 3: basal diet contained 0.25% celery seeds powder, 4: basal diet contained 0.50% celery seeds powder, 5: basal diet contained 0.75% celery seeds powder, 6: basal diet contained 1.00% celery seeds powder, 7: basal diet contained 0.10% exogenous enzymes plus 0.25% celery seeds powder, 8: basal diet contained 0.10% exogenous enzymes plus 0.50% celery seeds powder, 9: basal diet contained 0.10% exogenous enzymes plus 0.75% celery seeds powder, 10: basal diet contained 0.10% exogenous enzymes plus 1.00% celery seeds powder).

the numbers of birds for each replicate (cage) were five birds and each treatment included five replicates.

the results of statistical analysis showed significant differences (p<0.05) among treatments for egg mass (8.82, 9.32, 9.63, 9.11, 8.86, 8.79, 8.50, 9.37, 8.84 and 10.24 gms egg/bird/day) and for feed conversion ratio (3.33, 3.96, 3.05, 4.05, 3.30, 3.77, 3.02, 2.49, 3.28 and 3.35 gms feed per gram of egg respectively).

the lowest feed cost for egg production was for the seventh dietary group (1.66, 1.98, 1.52, 2.02, 2.07, 1.87, 1.51, 1.25, 1.64 and 1.67 dollars feed cost per one kilogram of egg produced).

the were significant (p<0.05) differences among treatments for shell thickness, weight of yolk, yolk color and the albumen diameter.
