Abstract

The aim of our study was to investigate the impact of carnosic acid (CA), selenate (VISe) or selenized yeast (YSe) on concentrations of fatty acids (FA), tocopherols, cholesterol and malondialdehyde in the periintestinal fat (PIF) and muscles of lambs. Male lambs were fed the control diet containing rapeseed (RO) and fish (FO) oils, the CA diet containing RO, FO and CA, the YSe-CA diet with RO, FO, CA and YSe, and the VISe-CA diet with RO, FO, CA and VISe. The experimental diets with CA, irrespective of the presence of YSe or VISe, decreased sums of saturated FA (SFA) and the thrombogenic SFA in the PIF compared to the control. The experimental diets increased the Δ9-desaturation capacity in the PIF compared to the control. The experimental diets with YSe or VISe reduced sums of long-chain polyunsaturated FA in the PIF compared to the control and CA diets. The PIF and muscles of lambs fed the VISe-CA diet were characterised by the highest hypocholesterolemic/hypercholesterolemic-FA ratio, and lower modified atherogenic index compared to the control.

饲粮中添加鱼油、菜籽油、鼠尾草酸和不同化学形式的硒会影响羔羊肠周脂肪中的脂肪酸分布和选定组织的营养特性指标

本研究旨在探讨鼠尾草酸(CA)、硒酸盐(VISe)或硒化酵母(YSe)对羔羊肠周脂肪(PIF)和肌肉中脂肪酸(FA)、生育酚、胆固醇和丙二醛浓度的影响。饲喂含有菜籽油和鱼油的对照饲粮、含有菜籽油、鱼油和鱼油的亚麻籽饲粮、含有菜籽油、鱼油和鱼油的亚麻籽饲粮、含有菜籽油、鱼油和鱼油的亚麻籽饲粮、含有菜籽油、鱼油和鱼油的亚麻籽饲粮和含有菜籽油、鱼油、鱼油和鱼油的亚麻籽饲粮。与对照组相比，添加CA的实验日粮，无论是否存在YSe或VISe，都减少了PIF中饱和脂肪酸(SFA)和血栓性SFA的数量。与对照组相比，试验饲粮提高了PIF的Δ9-desaturation能力。与对照组和CA饲粮相比，添加YSe或VISe的试验饲粮减少了PIF中长链多不饱和脂肪酸的含量。与对照组相比，饲喂VISe-CA日粮的羔羊的PIF和肌肉具有最高的低胆固醇/高胆固醇- fa比率，以及较低的改良动脉粥样硬化指数。

期刊介绍： Agricultural and Food Science (AFSci) publishes original research reports on agriculture and food research related to primary production and which have a northern dimension. The fields within the scope of the journal include agricultural economics, agricultural engineering, animal science, environmental science, horticulture, plant and soil science and primary production-related food science. Papers covering both basic and applied research are welcome. AFSci is published by the Scientific Agricultural Society of Finland. AFSci, former The Journal of the Scientific Agricultural Society of Finland, has been published regularly since 1928. Alongside the printed version, online publishing began in 2000. Since the year 2010 Agricultural and Food Science has only been available online as an Open Access journal, provided to the user free of charge. Full texts are available online from 1945 on.
