COMPARISON OF THE QUALITY OF MEAT CUTS AND INTERNAL VISCERA OF BROILERS FED DIETS CONTAINING VARYING LEVELS OF CYPERUS ROTUNDUS
This study evaluated the impact on various characteristics of broiler chicken meat from adding 2.5, 5, and 7.5 g/kg of Cyperus rotundus powder and 300 mg/kg of vitamin E to their feed. The studied traits were the weight of edible and inedible viscera and primary and secondary cuts, as well as variou...

| Summary: | This study evaluated the impact on various characteristics of broiler chicken meat from adding 2.5, 5, and 7.5 g/kg of Cyperus rotundus powder and 300 mg/kg of vitamin E to their feed. The studied traits were the weight of edible and inedible viscera and primary and secondary cuts, as well as various blood parameters such as glucose levels, blood plasma proteins, plasma lipid profile, and liver enzyme activity associated with amino group transfer. The results indicated that adding the powder as a natural additive provided superior results compared to vitamin E and the control in improving the dressing percentage without edible giblets after the end of the feeding period. Adding 7.5 g/kg to the feed produced the best results at 75.69% followed by 5 g/kg (75.36%), and 2.5 g/kg (73. 03%) compared to 72.5% and 70.3% for the diet containing vitamin E and the control, respectively. Furthermore, adding Cyperus powder compared to vitamin E and the control significantly improved the dressing percentage with edible giblets at 78.86%, 78.30%, 76.86%, 76.20%, and 73.76%, respectively. It also led to a significant increase in the percentage of weight the primary carcass parts. The thigh parts reached 29.1%, 28.3%, 25.63, 24.4%, and 21.70%, while it was 38.73%, 38.16%, 34.96%, 34.76%, and 32.56% for the breast, respectively. However, adding Cyperus powder did not lead to any improvement in the weight of secondary parts such as the wings, neck, and back. The results also showed that Cyperus powder supplements in the feed improved blood glucose levels, as they reached 255.3, 257.3, 251.6, 243.3 and 232.3 dl\mg in birds fed diets containing 2.5, 5, and 7.5 g/kg of the powder and 300 mg/kg of vitamin E and the control treatment, respectively. No significant effect was observed in total protein, albumin, globulin, creatinine, and uric acid levels compared to the control group. The results show that adding the powder to bird feed had a significant effect on the blood lipid profile. Cholesterol blood content, triglycerides, and LDL registered decreases in birds fed diets containing all the experimental Cyperus powder and vitamin E levels and the control at 171.3, 175, 183.3, 183.6, and 195.9 mg/100 ml, 112.3, 114.6, 134.6, 135.3, and 155.3 mg/100 ml, and 103.47, 107.73, 112.60, 112.40, 126.40 mg/100 ml, respectively. However, a significant increase was observed in HDL values, at 45.33, 44.33, 43.66, 44.33, and 37.66 mg/100, respectively. ALT and AST enzyme concentrations decreased significantly while that for the ALP enzyme increased in the treatments involving sedge powder additions compared to the control feed |
