Özet
This research examined effects of gender and dietary inclusion of date palm extract (DPE) on growth,
carcass characteristics, oxidative status and serum characteristics of Japanese quail. One thousand chicks
were allocated to five replicates of treatment and gender groups composed of 20 chicks. The treatments
were a basal diet and four groups augmented with 0.25%, 0.50%, 0.75%, and 1.00% DPE. The interaction of
gender and treatment was significant for bodyweight (BW) at 42 days, average daily bodyweight gain
(BWG), feed intake (FI), weights of most carcass components, and the serum profile. Females had better
performance to 42 days than males (P <0.05). In addition, females had higher hot and cold carcass weights,
breast percentage, liver percentage, intestine percentage, total protein, albumin, triglyceride (TRIG), total
antioxidant status (TAS), total oxidant status (TOS), and oxidative stress indexes (OSIs) (P <0.001). Males
had higher percentages of hot carcass, cold carcass and heart, and their levels of cholesterol (CHOL), highdensity lipoprotein (HDL), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) values
were greater than females (P <0.001). Birds fed 0.50% DPE grew faster, were more efficient, and had
heavier live and carcass weights at 42 days than those fed the basal diet. However, treatment effects and
their interaction with gender on growth, feed intake and the serum profile were unremarkable compared to
the gender main effect. Dietary augmentation with 0.50% DPE might enhance the performance of quail
between 14 and 42 days old
