| Abstract | ||
| This study was conducted to examine the effect of substituting 15, 20, 25 and 30 % of energy supplied by corn in a control diet with energy from by-product of palm oil extraction (POE) to enhance productive performance and combat heat stress of Japanese quail. A total of 375, 7-d old Japanese quail chicks were randomly distributed following a completely randomized design into 5 treatment groups (N = 75 chicks/group). Each treatment having three replications (n=25 chicks/ replicate). Results indicated that live weight and gain differed significantly (P ≤ 0.05) among treatment groups. While feed intake, protein and energy intake insignificantly affected. However, FCR recorded the best values for birds fed diet inclusion different levels of POE compared with control group. No mortalities observed among the treatments along the experimental period. Moreover, there were improvements for most hematological and biochemical parameters due to feeding POE. Therefore, lipid profile significantly (P ≤ 0.05) decreased, when POE increased in the diets. The findings showed that the histomorphometric parameters significantly (P ≤0.05) improved due to feeding POE. The highest economical efficiency observed for groups fed diets inclusion different levels of POE. Therefore, on the basis of the current results, we concluded that adding by-product POE up to 30% to the quail diets has no adverse effect on their productive performance or physiological status as well as the addition of POE gets higher economic efficiency. | ||
