This study evaluated the effects of aqueous or cyclodextrin extracts on broiler growth performance, welfare, meat composition, and oxidative stability. The cyclodextrin treated group showed higher final body weight and both treatment groups had lower pododermatitis score. Thigh meat protein content increased and fat content decreased in both treatment groups, and meat color was also improved. The supplementation of broilers diet with cyclodextrin extract increased n-3 and n-6 fatty acids content, as well as PUFA/SFA and H/H ratios in thigh meat.
Background: Medicinal plants exhibit significant effects on broiler physiology and production. This trial aimed to evaluate the effects of dietary supplementation with an aqueous or cyclodextrin extract derived from a mixture of Origanum vulgare L., Camelina sativa L. Crantz, Crithmum maritimum L., and Allium sativum L. at the level of 0.1% per kg of dry matter (DM) on broiler growth performance, welfare, meat chemical composition, and oxidative stability.Results: Cyclodextrin treated group presented significantly higher final body weight, while feed intake and FCR were unaffected by the treatments. Both aqueous and cyclodextrin treated groups had significantly lower pododermatitis score compared to the control group. Additionally, both treatment groups presented increased thigh meat protein content and lower fat content, likewise meat color was also positively affected by both treatments. Supplementation of broilers diet with the cyclodextrin extract also resulted in n-expressionry sumexpressiontion n-3 fatty acids and n-expressionry sumexpressiontion n-6 fatty acids increase. The PUFA/SFA and H/H ratios were also increased in the thigh meat of both supplemented groups compared to the control group.Conclusion: The application of aqueous or cyclodextrin extracts yielded positive results on meat composition, and supported growth performance, welfare, and the oxidative status of the chicken meat.
