Performance, Lymphoid Organ, and Carcass Characteristics of Broiler Chicken as Affected by Feed Supplementation with Vitamin C and Vitamin E

The purpose of this study was to look at the potential impacts of vitamin C, vitamin E, or a combination of the two on growth performance, carcass traits, and lymphoid organs. ۳۰۰ Cobb male broiler chicks were used in the experiment; they were divided into ۴ treatments, each with ۵ subgroups of ۱۵ birds. The following are the four treatment diets: Diet ۱ (control): ۸% sunflower oil (SO); Diet ۲: ۸% SO + ۲۵۰ mg/kg vitamin C; Diet ۳: ۸% SO + ۲۰۰ mg/kg vitamin E; Diet ۴: ۸% SO + mix (۲۵۰ mg/kg vitamin C + ۲۰۰ mg/kg vitamin E). The addition of vitamins C and E had no impact on the growth's efficacy. Over ۴۲ days, neither vitamin C nor vitamin E significantly affected the body weights (BW) of broilers. There were no differences in body weight gain (BWG) between birds given vitamin C or vitamin E, but the two together boosted BWG significantly (P>۰.۰۵). Broilers on vitamin-supplemented diets consumed more feed than the control group did. Feed conversion rates (FCR) were significantly (P>۰.۰۵) higher in the vitamin experimental groups than in the control group (۲.۸, ۲.۹ versus ۱.۹۵). Therefore, the feed consumed was not efficiently utilized by the broiler chickens. However, introducing a blend of vitamins C and E to the meal significantly (P>۰.۰۵) improved the birds' FCR at a ratio of ۱.۹۵ when compared to the vitamin C or E groups. All vitamin supplementation significantly (P>۰.۰۵) increased carcass yields in comparison to the control diet. There were no appreciable weight changes between the spleen, liver, and heart (P>۰.۰۵). There were no weight differences across the dietary treatments for the spleen, liver, and heart (P>۰.۰۵) compared to the control group. When compared to the control diet and other dietary treatments for the C or E vitamins, the weights of the spleen, liver, and heart were larger (P ۰.۰۵) in broilers fed a diet enriched with a combination of vitamin C and vitamin E. When compared to the control diet, vitamin dietary interventions had an impact on Fabricius bursa weight (P>۰.۰۵). The trial's findings recommend adding vitamins C and E to sunflower oil to maintain animal health and boost their capacity for development. The negative effects of lipid peroxidation and environmental stress factors may be lessened by taking vitamin C and vitamin E supplements together. To identify and quantify the essential antioxidant vitamin for chicken productivity, more research is required.The purpose of this study was to look at the potential impacts of vitamin C, vitamin E, or a combination of the two on growth performance, carcass traits, and lymphoid organs. ۳۰۰ Cobb male broiler chicks were used in the experiment; they were divided into ۴ treatments, each with ۵ subgroups of ۱۵ birds.
