چکیده مقاله:
This study was performed to evaluate the efficacy of two levels of dietary oregano essential oil (OEO) on growth performances, biochemical, hematological parameters, and intestinal histomorphology in Japanese quail. A total number of ۹۹ quail chicks were divided into three groups (۳۳ quails per group): Control, OEO ۱۵۰ mg kg-۱, and OEO ۳۰۰ mg kg-۱ treated groups for ۴۲ days. Feed conversion ratio (FCR), feed intake, weight gain, and edible organ weight were recorded. Biochemical and hematological parameters were determined. Histomorphological examination of hepatic and intestinal tissues was performed. FCR was significantly improved and feed intake was significantly decreased in OEO ۱۵۰ mg kg-۱ group compared to control. No detectable changes were observed in the lipid profile. Meanwhile, total protein, albumin, globulin, and H/L ratio were significantly increased in OEO ۳۰۰ mg kg-۱ at day ۲۱. Uric acid and creatinine were significantly increased in the OEO ۳۰۰ mg kg-۱ group at day ۴۲. A significant increase was observed in the whole thickness of the small intestine in the OEO ۱۵۰ mg kg-۱ group besides a significant increase in villi length, width, and crypt depth. Vacuolar and fatty degeneration of the hepatocytes along with Kupffer cell hypertrophy was observed in OEO ۳۰۰ mg kg-۱ group. It was concluded that OEO ۱۵۰ mg kg-۱ improved the quail’s performance, intestinal histomorphometry as well as hematological parameters with no negative impacts on biochemical parameters.
