The purpose of the study was to assess the effect of the grapeseed meal, added to slow-growing Hubbard broilers diet high in polyunsaturated fatty acids (PUFA) due to the dietary flaxseed meal. The 7-wk feeding trial used 80 broiler chicks (14 d), assigned to two groups: control (C) and E, with 4 replicates of 10 chicks/group. The basal diet was similar for both groups during both feeding stages. The diet for group E was supplemented with 3% grapeseed meal. Six broilers from each group were slaughtered in the end of the feeding trial, and blood, breast and leg meat samples were collected. Serum cholesterol was significantly lower in group E (110.85 mg/dL), than in group C (146.82 mg/dL). The PUFA concentration was significantly higher in group E, than in group C, both in the breast (31.34 %, compared to 27.73 % total fatty acid methyl ester - FAME) and in the leg (32.44 %, compared to 30.06 % total FAME). The cholesterol concentration was significantly lower in group E (42.52 mg), than in group C (60.91 mg/100 g fresh sample) in the leg. After 7 d of refrigeration, the peroxide value was significantly lower in group E (8.11 meq), than in group C (8.79 meq/kg fat) in the breast meat, while fat acidity was significantly lower in group E (40.82 mg KOH), than in group C (43.99 mg KOH / g fat) in the leg. The dietary 3 % grapeseed meal, used as natural antioxidant, in PUFA-enriched broiler diets, had positive effects on the blood parameters and meat quality.
