The purpose of the study was to determine the effects of raspberry seed oil on the slaughter performance traits, plasma lipid concentration and meat quality of purebred Termond White rabbits ( = 42; 18♂, 24♀). In each group (3 × = 14; 6♂, 8♀), the experimental animals were fed a complete pelleted feed with constant access to drinking water. Rabbits in the first experimental group received a feed ration enriched with a 1% addition of raspberry seed oil, while rabbits in the second experimental group were given a 2% addition of the same oil. These animals were slaughtered on day 84. The addition of raspberry seed oil did not significantly affect the slaughter performance traits of the rabbits ( > 0.05). It also did not significantly affect the fat content, shear force, hardness, springiness, cohesiveness or chewiness of the meat obtained from the rabbits' muscle. However, the experiment showed that the addition of raspberry seed oil had a significant effect on the fatty acid profile of rabbit meat ( ≤ 0.05). Even a small share of this oil in the feed ration significantly increased the level of linoleic acid ( ≤ 0.05). This study showed that feeding pellets containing an oil supplement with a high content of unsaturated fatty acids had a positive effect on rabbits' plasma lipid levels.
本研究的目的是确定树莓籽油对纯种特尔蒙德白兔（ = 42只；18只雄性，24只雌性）屠宰性能性状、血浆脂质浓度和肉质的影响。在每个组中（3× = 14只；6只雄性，8只雌性），实验动物喂食完全颗粒饲料，并可随时饮用饮水。第一实验组的兔子接受添加1%树莓籽油的饲料定量，而第二实验组的兔子则添加2%的相同油。这些动物在第84天屠宰。添加树莓籽油对兔子的屠宰性能性状没有显著影响（ > 0.05）。它也没有显著影响从兔子肌肉获得的肉的脂肪含量、剪切力、硬度、弹性、内聚性或咀嚼性。然而，实验表明，添加树莓籽油对兔肉的脂肪酸谱有显著影响（ ≤ 0.05）。即使饲料定量中这种油的比例很小，也能显著提高亚油酸水平（ ≤ 0.05）。本研究表明，喂食含有高含量不饱和脂肪酸油补充剂的颗粒饲料对兔子的血浆脂质水平有积极影响。
