Abstract

In the present study pomegranate peels and avocado peels and seeds vacuum microwave extraction solid by-products were supplemented in corn silage in order to investigate the effects on meat quality and growth rate in broiler chicken. 50 broilers were divided in two groups treated with experimental or usual fed for 43 days (group A: 25 broilers fed with avocado and pomegranate by-products and group B: 25 broilers fed with corn-silage used as control). The results showed that broiler chickens fed with diet supplemented with a mixture of pomegranate avocado by-products (group A) shown significant differences in chicken leg meat quality improving in significant level the proteins and fatty acids contents in breast and leg meat respectively. More specific ω3 and ω6 fatty acids contents were three times higher than in group B. Moreover protective effect on the decomposition of polyunsaturated fatty acids induced by free radicals presented in chicken meat based on the evaluation of lipid peroxidation by measuring thiobarbituric acid reactive substances. Pomegranate peels, avocado peels and seeds by-products appeared slight reduction on meat production while it was found to improve the qualitative chicken meat characteristics. Regarding the production costs, it was calculated that the corn-silage supplementation used in this study lead to a 75% lower cost than the commercial corn-silage used for the breeding of broilers.
