ABSTRACT: The effect of rearing system (pasture with
supplementation 15% crude protein OUT15 vs indoorIND)
on meat nutritional and nutraceutical properties was evaluated in twenty
Podolian young bulls. Meat quality characteristics
were measured on three different muscles (Longissimus dorsi, LD, Semimembranosus,
SM, Semitendinosus, ST), vacuum-packaged and chilled stored at 2℃ - 4℃ for 15 days. No differences were found on chemical composition in meat from
animals reared with different rearing system. Pasture with supplementation
produced an improvement in fatty acid composition with a higher polyunsaturated
fatty acid percentage, particularly, conjugated linoleic acids (CLA) and
very long chain ω3 PUFA, such as eicosapentaenoic
acid (EPA) and docosahexaenoic acid (DHA). Meat from young bulls reared at
pasture with supplementation showed in all examined muscles the highest α-tocopherol content compared with meat
from IND group. On the other hand, malondialdehyde content was not affected by
the feeding treatment.
