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 () 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 () (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 (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.
现代消费者对脂肪含量较低且饱和脂肪酸水平较低的肉类需求日益增长,因为饱和脂肪酸被认为会增加患冠心病的风险。在意大利南部,詹蒂莱·迪普利亚品种是农场中最常见的品种之一,其幼羊常被食用。本研究评估了含有挤压亚麻籽()的日粮对詹蒂莱·迪普利亚幼羊生长性能、胴体性状和肉质的影响。36只雄性羔羊在约20日龄时断奶,分为三组——每组分别饲喂对照日粮(C)、含有3%挤压亚麻籽的日粮(L)或含有3%挤压亚麻籽和0.6%牛至()的日粮(L + O)。各组羔羊的生长性能以及屠宰和解剖数据没有差异。日粮处理对(Ll)的质量和化学成分没有显著影响。L组Ll肉中亚油酸的含量显著更高,这对n-3多不饱和脂肪酸的总含量以及n-6/n-3比值产生了积极影响。在感官特性方面获得的良好结果符合市场消费者的要求。
