Abstract
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. 300 Cobb male broiler chicks were used in the experiment; they were divided into 4 treatments, each with 5 subgroups of 15 birds. The following are the four treatment diets: Diet 1 (control): 8% sunflower oil (SO); Diet 2: 8% SO + 250 mg/kg vitamin C; Diet 3: 8% SO + 200 mg/kg vitamin E; Diet 4: 8% SO + mix (250 mg/kg vitamin C + 200 mg/kg vitamin E). The addition of vitamins C and E had no impact on the growth's efficacy. Over 42 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>0.05). Broilers on vitamin-supplemented diets consumed more feed than the control group did. Feed conversion rates (FCR) were significantly (P>0.05) higher in the vitamin experimental groups than in the control group (2.8, 2.9 versus 1.95). 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>0.05) improved the birds' FCR at a ratio of 1.95 when compared to the vitamin C or E groups. All vitamin supplementation significantly (P>0.05) increased carcass yields in comparison to the control diet. There were no appreciable weight changes between the spleen, liver, and heart (P>0.05). There were no weight differences across the dietary treatments for the spleen, liver, and heart (P>0.05) 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 0.05) 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>0.05). 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.
