Description
Summary:[A study on effects of forage type on some qualitative traits of milk was carried out on 8 Martina Franca lactating asses. The animals were divided into two groups: CTR (hay + concentrate feed) and TRT (fresh herbage + concentrate feed). The experimental trial lasted 63 d. On feeds and milk, fatty acids, by GC, and flavours, by SPME-GC/MS, were determined. In milk the highest differences were observed for: PUFA (CTR = 21.56% vs TRT = 30.51%; P=0.001), particularly for PUFA-w3 (CTR = 9.31% vs TRT = 18.28%; P0.001), referable to linolenic acid levels, doubled for group TRT (16.33%) compared with CTR (8.43%); for Atherogenic (CTR Lo studio degli effetti della base foraggera su alcuni aspetti qualitativi del latte è stato condotto su 8 asine in lattazione, di razza Martina Franca, divise in due gruppi: CTR (fieno + mangime) e TRT (erba + mangime). La prova ha avuto una durata di 63 d. Sugli alimenti e sul latte sono stati determinati gli acidi grassi, mediante GC, e i flavour, mediante SPME-GC/MS. Nel latte le maggiori differenze sono state riscontrate: per i PUFA (CTR = 21,56% vs TRT = 30,51%; P=0,001), in particolare per i PUFA-w3 (CTR = 9,31% vs TRT = 18,28%; P0,001), imputabili ai livelli di acido linolenico, raddoppiati per il gruppo TRT (16,33%) rispetto al CTR (8,43%); per gli indici Aterogenico (CTR
