Composizione acidica del grasso delle carni di vitelloni podolici di 14 e 18 mesi di età

In the last few years, has been growing a huge interest in the fat content of the nutrients due to the relationship between many studies made on diets with high percentage of saturated fatty acids and heart diseases. Limiting the input of saturated fatty acids and consuming large amounts of polyunsaturated fatty acids (PUFA), particularly those of ω3-PUFA series [acid α-linoleic, EPA (C20:5 ω-3), DHA (C22:6 ω-3), acids of the CLA series] have as a result the reduction of the heart pathologies, the increase of the immunological, anti-inflammatory and against cancer defenses; the cerebral and visual system development of fetus. Our studies were based on evaluating the nutritional characteristics and the nutraceutical propriety of podolian meat with a particular attention on the content of fatty acids of the series mentioned before. For this reason, we compared all the results taken by the analysis of samples of Longissimus dorsi of podolian bulls slaughtered at 14 or 18 months of age, reared in groups of 6 animals with two different systems (indoor rearing-system and semi free-range). Their comparison shows that, generally, the content of fatty acids of the ω3-PUFA series is higher on the animals reared with the semi-free range, both on 14 and 18 months of age, trend showed by the raw and the cooked samples.
