Reduction of body fatness and meat fat content in lambs by supplementing their diet with isomerised grapeseed oil

Investigated was the effect of isomerised grapeseed oil supplementation on carcass composition and body fat in lambs and fat content of their meat. Grapeseed oil alkaline isomerisation and crystallisation with urea resulted in synthesis of conjugated dienes amounting to linoleic acid (CLA) 77.6% FFA. The enrichment of fattening lambs´ rations with the additive at 18 g/animal/day did not influence body weight gain, carcass weight and Longissimus dorsi parameters (weight, width,depth). However, it reduced body fatness by 19 to 25%, and decreased the fat content of muscle tissue by 17 to 22 percentage points.
