There were important difference in meat yield, composition and eating quality between the breeds and production systems after the short growth period. Texels and grass-fed lambs had high proportions of n-3 PUFA in muscle. Texels also had a high proportion of 18:2 n-6, similar to lambs fed concentrates. However, the differences in flavour between production systems were much greater than those between breeds. The results suggest that lower oxidative breakdown of muscle lipids in grass-fed animals is important, perhaps due to greater consumption of natural antioxidants. Grass feeding also increases CLA levels which, along with n-3 PUFA, are beneficial in human nutrition. |
