Effects of dried okra fruit (Abelmoschus esculentus L.) powder on growth, carcass characteristics, blood indices, and meat quality of stored broiler meat

The present study investigated the impacts of dried okra fruit powder (DOFP), used as a natural feed supplement, on growth, carcass, blood, and meat quality parameters of broilers. A total of 240 unsexed, one-week-old chicks were randomly allotted to 4 equal groups with 6 replicates in each group (i.e., 10 birds/replicate). The dietary treatments consisted of the basal diet as control, and 3 DOFP groups, supplemented with 1.0, 2.0, and 3.0 g DOFP/kg feed, respectively. The results showed that the highest values of live body weight and body weight gain were observed in the group with 1.0 g of DOFP/kg of feed during the fifth week of age and between 1 and 5 wk of age, respectively. During 1 to 3 wk of age, daily feed consumption of chicks fed DOFP-supplemented diets increased numerically with increasing DOFP levels. Dietary treatments significantly depressed liver, thigh, and dressing fat percentages. Chicks fed the diet containing 1.0 g of DOFP/kg of feed had the lowest values for serum urea and creatinine compared with the other treatment group. In addition, the concentration of liver enzymes decreased with increasing DOFP levels, except for the groups fed 3.0 and 1.0 g of DOFP/kg of diet. Oxidative rancidity of broiler meat samples containing DOFP in their diets was lower than that of the control samples, throughout the storage period. It can be concluded that DOFP is a useful phytogenic additive, which can lower the percentage of abdominal fat of the carcass, as well as alanine aminotransferase, urea, and creatinine in the blood. Furthermore, all sensory characteristics of the meat were improved by the addition of DOFP to broiler diets. It could be concluded that DOFP can be used as a natural supplement in broiler diets for improving growth performance and reducing abdominal fat, blood creatinine, and urea.
