Nuevas alternativas en la alimentación del cerdo Ibérico: uso de la avellana Gevuína

Abstract

Iberian pig production in the free-range system is limited by acorn production. In order to provide an alternative, the use of the Gevuina hazelnut has been proposed. Pigs were split up in two groups (n = 6 per group), one of those was provided with commercial feed (according to appetite) and the other was given a commercial feed and 2 kg of hazelnut/ animal and day from 126,6 ± 4,7 kg of weight until slaughter. The hazelnut analysis revealed they have a great proportion of fat (44 %), with a high amount of monounsaturated fatty acids (MUFA) (93.94 %), of which the main fatty acids where palmitoleic acid (29.99 %) and oleic acid (50.60 %). The C18:1n-9 concentration increased in the hazelnut group, as time increased (P = 0.0001), this led to a greater decrease of C16:0 concentration (P = 0.001) in the hazelnut group than in the other group. Although, the final level of C18:1n-9 in the hazelnut group did not exSerrano et al. ITEA-Inf. Tec. Econ. Agrar.
