The paper aimed to characterize sea buckthorn meal (SBTM) and to assess his effect in the diet of hea t- stressed broiler (32˚C). A total of 60 Cobb 500 broiler chicks were assigned in two groups (C, E) which included in the diet corn and soybean meal as main ingredients. Compared with the C diet, the experimental diet (E diet) included the addition of 1% of SBTM. Samples of SBTM (purchased from a local producer) and samples of compound feed were analysed for their proximate composition, minerals, vitamin E and antioxidant activity. A 5-day balance sheet study was conducted on broilers in the grower stage (week 4) and in the finisher stage (week 6). Performance parameters (0-42 days) were recorded. Results showed that SBTM had an important concentration of polyphenols (11.65 mg/g GAE), lutein and zeaxanthin (91.80 mg/kg), expressing a high antioxidant capacity (99.84 mM ascorbic acid equivalent, 92.1 mM vitamin E equivalent). Dietary SBTM is a valuable by-product which can be used in broiler diet without negatively affecting the coefficients of apparent absorption of nutrients and performance, even in heat stress conditions.
