| Summary: | ABSTRACT The present study was conducted to determine the effects of supplemented juniper berry (Juniperus communis) on fattening performance and some carcass traits of quails. A total of 150 one-day-old Japanese quail chicks were randomly divided into five groups (one control and four treated groups) with three replicates. Four different juniper berry levels (0.5, 1, 1.5, and 2%) and a control treatment (0%) were added to the diet. Juniper berry supplementation to the diets initiated at the end of the 1st week and sustained for seven weeks. Live weight, feed intake, and feed conversion ratio during the trial and some carcass traits after slaughter were determined. Juniper berry supplementation in the diet during seven weeks of growing period significantly increased body weight, cumulative feed intake, and feed conversion ratio of the treated groups. Carcass weight, carcass yield, and breast yield were also significantly increased by supplemented juniper berry. No significant difference was observed between viability of different groups. Supplementation of 0.5-1% juniper berry in quail diets has positive impacts on fattening performance and carcass traits.
