Effects of mulberry leaves on growth performance, carcass characteristics, and meat quality of Japanese quail

This experiment was conducted to determine the effects of mulberry leaves on performance, carcass characteristics, and meat quality of Japanese quail. A total of 240 one-day-old Japanese quail chicks were randomly allocated to three experimental groups and fed a basal diet (control) and the basal diet plus 50 g/kg and 100 g/kg mulberry leaf meal (MLM) for 42 days. By the end of the study, performance parameters of quail fed the 100 g/kg MLM-supplemented diet were affected negatively. The highest carcass weight and carcass yield levels were exhibited in the control group. In terms of meat quality, the shear force of the breast meat of quail fed the diet with 100 g/kg supplemented MLM was higher than the other groups. The highest L* and hue angle values of breast meat were found in the 50 g/kg MLM group. Released water from the thigh meat in the control group was higher than in the experimental groups. The current study indicates that 50 g/kg MLM can be used easily in quail rations without any negative effects.
