Abstract
We analysed the effect of enriched housing on the sensory meat quality and fatty acid composition of longissimus muscle in 60 entire Rasa Aragonesa lambs, housed indoors for 5weeks in six pens (10 lambs/pen, 0.95m2/lamb, initial weight 17.13±0.18kg and carcass mean 12.23±0.23kg); three control pens (barren) and three enriched pens (straw, platform with ramps and a small ramp). The final weight, carcass weight, fatness scores and cooking losses of meat from enriched lambs (EG) were higher and pH24 was lower (P≤0.05). The EG lambs had more C18:0 and total SFA (P≤0.05). Lamb odour and grass odour were more intense in EG (P≤0.05). Overall liking was higher for EG (P≤0.05) and associated with tenderness (P≤0.0001). The results suggest that environmental enrichment can have effects on fatty acid composition and sensory meat quality. © 2014 Elsevier Ltd.
