The trial was carried out on 16 young Podolian bulls, divided into two groups: an "extensive rearing" group, reared exclusively on pasture and a "half-extensive rearing" group, with feeding supplementation. Bulls were slaughtered at the age of 18 months. The most representative muscles were sampled after a chilling period of 7 and 14 days, for the right and left hindquarters, respectively. The fatty acid profile of the fat was determined and data were analysed by ANOVA in order to evaluate the effect of muscle, chilling period and feeding system. The lowest SFA content was observed in Gluteobiceps, Gluteus superior and Semimembranosus muscles; Gluteus superior, Semimembranosus and Semitendinosus muscles had the highest incidence of MUFA. Gluteus superior, Semimembranosus, Semitendinosus and Vastus lateralis had the highest amount of PUFA.
Due gruppi di vitelloni Podolici allevati con due diversi regimi alimentari (solo pascolo e pascolo con integrazione alimentare), sono stati macellati a 18 mesi. Dopo un periodo di frollatura di 7 e 14 d, per le mezzene destre e sinistre, rispettivamente, sono stati prelevati campioni in corrispondenza dei più rappresentativi muscoli della carcassa. Sui campioni è stato determinato il profilo acidico del grasso, e per l'analisi statistica è stata utilizzata l'analisi della varianza per definire l'effetto del muscolo, del periodo di frollatura e del sistema di alimentazione. Nella carne dei muscoli del Gluteobiceps, Gluteus superior e Semimembranosus sono stati rilevati valori più bassi di SFA; valori più alti di MUFA sono risultati nella carne dei muscoli Gluteus superior, Semimembranosus e Semitendinosus. I muscoli Gluteus superior, Semimembranosus, Semitendinosus e Vastus lateralis sono risultati più ricchi in PUFA

Abstract
The trial was carried out on 16 young Podolian bulls, divided into two groups: an "extensive rearing" group, reared exclusively on pasture and a "half-extensive rearing" group, with feeding supplementation. Bulls were slaughtered at the age of 18 months. The most representative muscles were sampled after a chilling period of 7 and 14 days, for the right and left hindquarters, respectively. The fatty acid profile of the fat was determined and data were analysed by ANOVA in order to evaluate the effect of muscle, chilling period and feeding system. The lowest SFA content was observed in Gluteobiceps, Gluteus superior and Semimembranosus muscles; Gluteus superior, Semimembranosus and Semitendinosus muscles had the highest incidence of MUFA. Gluteus superior, Semimembranosus, Semitendinosus and Vastus lateralis had the highest amount of PUFA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
