Research on the influence of new diet formulations on the quality of fattening lambs meat

摘要

The strategies aiming to improve sheep meat quality by optimizing the dietary feeding factors have to use field experiments on fattening lambs. This experiment used two groups of Teleorman Tsigai sheep fed on diets with alfalfa hay and compound feed. The compound feed for the experimental group included 20.4% rapeseeds, while in the compound feed for the control group it replaced also 20.4% of sunflower meal from the classical formulation. The rapeseeds were used because of their high level of unsaturated acids, mainly linolenic acid (9.32%) compared to just 0.21% in the sunflower meal. This supplement was found in a better ratio (6:1) in the meat of the fattening lambs compared to 17:1 in the classical formulation. This induced moderate increases mainly of the omega 3 and 6 (C18:3n6; C18:3n3) fatty acids, which have antioxidant action at the cellular level, implicitly on human health
