Evaluating the interaction response of broiler chickens to in ovo feeding of Citrus aurantiifolia seed extract and its powder supplementation
This study aimed to evaluate the effect of in ovo injection and post-hatch supplementation of Citrus aurantiifolia seed on hatchability, growth performance, antioxidant capacity, immune organs weight, and intestinal morphology of Cobb 500 broilers chickens. On day 18 of incubation, 450 fertile eggs...

| Summary: | This study aimed to evaluate the effect of in ovo injection and post-hatch supplementation of Citrus aurantiifolia seed on hatchability, growth performance, antioxidant capacity, immune organs weight, and intestinal morphology of Cobb 500 broilers chickens. On day 18 of incubation, 450 fertile eggs were randomly allocated into three sets: non-injected group, 0.5 µg/ml Citrus aurantiifolia seed extract (CASE) group and 0.75 µg/ml CASE group. After hatch, each set was allocated into two groups (5 replicates of 10 birds/replicate each) and was fed on a standard diet with or without Citrus aurantiifolia seed powder (CASP) supplementation (5 g/kg). The groups were divided as follows: IoCA0-C, IoCA0-CA, IoCA5-C, IoCA5-CA, IoCA75-C and IoCA75-CA where IoCA0-C was: non-injected group fed standard diet (negative control group), IoCA0-CA: non-injected and fed CASP supplemented diet (positive control group), IoCA5-C: 0.5 µg/ml of CASE-injected and fed standard diet, IoCA75-C: 0.75 µg/ml of CASE-injected and fed standard diet, IoCA5-CA: 0.5 µg/ml of CASE-injected and fed CASP supplemented diet and IoCA75-CA: 0.75 µg/ml of CASE-injected and fed CASP supplemented diet. The results revealed that the interaction between CASE in ovo injection at 0.5 µg/ml and dietary CASP supplementation at 5 g/kg in the diet increased body weight and weight gain (p < 0.001). The interaction between CASE in ovo injection and dietary CASP supplementation decreased the serum malondialdehyde concentration, the relative weight of the thymus and improved duodenum and ileum villus height (p < 0.05). In conclusion, in ovo injection and dietary supplementation of Citrus aurantiifolia seed powder can improve growth performance and the intestinal morphology of broiler chickens. |
