There is a growing demand by the modern consumer for meat containing less fat and lower levels of saturated fatty acids, which are considered to increase the risk of coronary heart disease. In southern Italy, the Gentile di Puglia breed is one of the most common on farms, and the light lambs are often consumed. The study evaluates the effect of a diet containing extruded linseed (Linum usitatissimum) on growth performances, carcass traits, and meat quality in Gentile di Puglia light lambs. Thirty-six male lambs are weaned at about 20 days of age, and divided into three groups—each group is either fed a control diet (C), a diet containing 3% extruded linseed (L), or a diet containing 3% extruded linseed and 0.6% oregano (Origanum vulgare) (L + O). The lambs’ growth performances and the slaughtering and dissection data did not differ between groups. Dietary treatments have no significant effect on the quality and chemical composition of Longissimus lumborum (Ll). The mount of linoleic acid in Ll meat is significantly higher in the L group, and this positively affected the total content of n-3 Polyunsaturated Fatty Acid, as well as the n-6/n-3 ratio. The good results obtained concerning the sensory traits meet the requirements of the market’s consumer.

外邦人的普利亚小羊羔的体组成，肉品质和感官品质：牛至和亚麻籽的膳食补充剂的影响

现代消费者对包含较少脂肪和较低含量的饱和脂肪酸的肉的需求正在增长，这被认为会增加患冠心病的风险。在意大利南部，Gentile di Puglia品种是农场中最常见的品种之一，经常食用轻羊羔。这项研究评估了含有亚麻籽（亚麻籽）的日粮对Gentile di Puglia羔羊的生长性能，car体性状和肉质的影响。36只公羊羔在大约20天大时断奶，分为三组-每组饲喂对照饮食（C），含3％膨松亚麻籽的饲料（L）或含3％膨化亚麻籽的饲料亚麻籽和0.6％的牛至（牛至））（L + O）。各组之间的羔羊生长性能以及屠宰和解剖数据没有差异。饮食疗法对腰果（Longissimus lumborum（L1））的质量和化学组成没有明显影响。L组中L1肉中亚油酸的含量显着更高，这对n-3多不饱和脂肪酸的总含量以及n-6 / n-3比率产生了积极影响。在感官特性方面获得的良好结果满足了市场消费者的需求。
