Sažetak
Oils enriched with EPA (PBE1) and DHA (PBE2) were combined with sunflower and linseed oils and supplemented to broiler diets in the amount of 5% with the aim to assess their effects on male broiler carcass and meat quality. Experiment was carried out from 22nd to 42nd day of fattening. Broilers were divided into groups: A (2.75% sunflower oil + 2% linseed oil + 0.25% PBE1), B (2.75% sunflower oil + 2% linseed oil + 0.25% PBE2), C (2.50% sunflower oil + 2% linseed oil + 0.50% PBE1), D (2.50% sunflower oil + 2% linseed oil + 0.50% PBE1). Diets contained 20% crude proteins and 13.5 MJ ME/kg. Final weights in groups A, B, C and D were 2781.80g, 2802.80g, 2822.75g and 2673.60 g, respectively. Food conversion into weight gain from 4th-6th week was 2.03 kg, 2.01 kg, 1.98 kg and 2.06 kg, respectively, and from 1st day – 6th week 1.82 kg, 1.81 kg, 1.80 kg and 1.86 kg, respectively. Dressing percentage was 68.64%, 68.81%, 71.54% and 69.13%, respectively. Portions of breasts and thighs with drumsticks proved no significant differences (P 0.05) between feeding treatments. Dietary oil supplementation in finishing phase of fattening significantly affected some parameters of breast meat quality (color L*, P 0.01 and pH2, P 0.05). Deposition of n-6 PUFA in breast muscle lipids was affected by feeding treatments (P 0.05). The highest portions of PUFA n-6 in total fatty acids were determined in group D (37.47%), then B (33.73%), A (32.43%), and lastly C (32.92%). The highest deposition of n-3 PUFA in breast muscle lipids was determined in group D (14.08%), which was significantly higher (P<0.05) if compared to C, B and A (11.02%, 11.08%, 11.34%, respectively). Compared to groups B and C (3.05:1, 2.99:1, respectively), significantly better n-6 PUFA / n-3 PUFA ratio (P<0.05) was determined in group D (2.67:1).
