Abstract

The present study was conducted to determine the effects of olive extract leaf and olive oil on growth performance, nutrient digestibility, carcass characteristics and intestinal morphology in Japanese quail. A total of 528 Japanese quail chicks 1-days-old were allocated to 6 treatments group with 4 replicates each containing 22 birds. This study was performed in a 2×3 factorial experiment with completely randomized design. Experimental treatments were included two levels of olive leaf extract (0, and 400 mg/kg) and three levels of olive oil (0, 2. 5 and 5%). The results was revealed that the average daily weight gain were significantly increased in diet containing 5 % of olive oil compared to control group (P<0. 05). The diet containing 2. 5 percent olive oil decreased average daily feed intake as compare to control diet (P<0. 05). The Ileum histomorphometry showed that crypt depth and height villus to crypt depth ratio in birds received 2. 5 and 5% olive oil decreased and increased compared with control group, respectively (P<0. 05). The results showed that the apparent digestibility of protein, ash, fat, phosphorus and energy in the control group was significantly lower than other treatments (P<0. 05). The apparent digestibility of fiber was higher in the treatment containing 5% olive oil and the treatment containing 400 mg/kg diet of olive leaf extract (P <0. 05). Diet containing 5% olive oil had the highest metabolizable energy compared to the other experimental groups (P <0. 05). In conclusion, the findings of this study suggests that dietary inclusion of olive oil up to 5 percent had benefit effects on quail production indices.
