Perfil de ácidos grasos de la carne de cordero de raza autóctona mallorquina en función del peso y de la alimentación

Abstract

The Balearic Islands have a long livestock tradition, but because of production intensification andtourism competition for territory, traditional systems based on grazing are at risk of disappearing,with negative environmental consequences. In order to preserve them, one option would be toimprove the commercialization of products derived from grazing through a quality mark. In Majorca,there is an autochthonous sheep breed raised on rangeland systems. Management data from 10farms were collected. Five groups of lambs were differentiated according to feed management andweight: suckling lambs-milk, light lambs-milk, light lambs-pasture, light lambs-concentrate andheavy lambs-concentrate. Fatty acid composition of Longissimus dorsi intramuscular fat wasanalyzed from 10 lambs of each group. No differences were found comparing animals with the samefeed management and different weights. Significant differences were found comparing animals withsimilar weight and different feed management. The best lipidic profile for human health wasobserved in grazing lambs fed without concentrate
