The aim of the present study was to assess the effects of partial replacement of rapeseed oil (RO) with fish oil (FO) combined with dietary supplementation of various antioxidants on the characteristics of lamb femur. Thirty male lambs were assigned to five dietary treatments and fed isoproteinous and isoenergetic diets for 35 days. The control diet was enriched with 3.0% RO, while the experimental diets were enriched either only with 2.0% RO and 1.0% FO or additionally with 0.1% carnosic acid, 0.1% carnosic acid and 0.35 ppm Se as selenized yeast, or 0.1% carnosic acid and 0.35 ppm Se as sodium selenite. After 35 days, the lambs were slaughtered, and the femur was dissected from the carcass of each animal and analyzed for morphometric, geometric, densitometric, and biomechanical properties. The dietary modifications, specifically the supplementation of FO and selenized yeast, significantly improved the geometric, densitometric, and biomechanical properties of lamb femur.
本研究的目的是评估用鱼油（FO）部分替代菜籽油（RO）并结合日粮添加各种抗氧化剂对羔羊股骨特性的影响。将30只雄性羔羊分配到五种日粮处理组，饲喂等蛋白和等能量日粮35天。对照日粮富含3.0%的RO，而实验日粮要么仅富含2.0%的RO和1.0%的FO，要么额外添加0.1%的肌醇六磷酸、0.1%的肌醇六磷酸和0.35 ppm以硒化酵母形式存在的硒，要么0.1%的肌醇六磷酸和0.35 ppm以亚硒酸钠形式存在的硒。35天后，宰杀羔羊，从每只动物的胴体上解剖出股骨，并分析其形态测量、几何、密度测定和生物力学特性。日粮改良，特别是添加FO和硒化酵母，显著改善了羔羊股骨的几何、密度测定和生物力学特性。
