The aim of this study was to determine whether diet modification with different doses of grapeseed oil or pomegranate seed oil will improve the nutritive value of poultry meat in terms of n-3 and n-6 fatty acids, as well as rumenic acid (cis-9, trans-11 conjugated linoleic acid) content in tissues diversified in lipid composition and roles in lipid metabolism. To evaluate the influence of applied diet modification comprehensively, two chemometric methods were used. Results of cluster analysis demonstrated that pomegranate seed oil modifies fatty acids profile in the most potent way, mainly by an increase in rumenic acid content. Principal component analysis showed that regardless of type of tissue first principal component is strongly associated with type of deposited fatty acid, while second principal component enables identification of place of deposition-type of tissue. Pomegranate seed oil seems to be a valuable feed additive in chickens' feeding.
本研究的目的是确定用不同剂量的葡萄籽油或石榴籽油进行饮食调整，是否会在n-3和n-6脂肪酸方面改善禽肉的营养价值，以及在脂质组成和脂质代谢中作用各异的组织中的瘤胃酸（顺式-9，反式-11共轭亚油酸）含量。为了全面评估所应用的饮食调整的影响，使用了两种化学计量学方法。聚类分析结果表明，石榴籽油以最有效的方式改变脂肪酸谱，主要是通过增加瘤胃酸含量。主成分分析表明，无论组织类型如何，第一主成分都与沉积脂肪酸的类型密切相关，而第二主成分能够识别沉积部位——组织类型。石榴籽油似乎是鸡饲料中有价值的添加剂。
