Effect of dietary supplementation of jujube fruit (Ziziphus jujuba) powder on performance, some biochemical parameters, and egg quality in quails (Coturnix coturnix japonica)

This study aimed to evaluate the effects of different dietary supplementation levels with jujube fruit powder on the performance, biochemical parameters, and egg quality characteristics of laying quails. A total of 60 quails (45 days old) were randomly assigned to treatments with different levels of jujube fruit powder: a basal diet (control) and diets supplemented with 5 g/kg (T1), 10 g/kg (T2), with five replicates per treatment (20 quails/treatment and four quails/replicate). The differences between 1-15 and 16-30 days for feed intake (p0.05). The yolk height (p0.05). According to the results of this study, jujube fruit, a rich energy source, can be used as an alternative supplement in poultry diets with positive effects on egg production and feed conversion ratio.
