Polyunsaturated fatty acids (), including n-6 and n-3 fatty acids, are essential for enhancing the performance and health of poultry. Avian species lack desaturase enzymes for endogenous synthesis of n-6 and n-3 fatty acids. This work aimed to determine the impacts of including soybean oil () and linseed oil () in quail diets on growth, lipid profile, hepatic and renal functions, immunity, and antioxidant status. A total of 350 Japanese quail chicks (1-wk-old) were randomly arranged into 7 dietary treatment groups. Seven isocaloric and isonitrogenous experimental basal diets were formed based on the nutritional requirements of growing Japanese quail. Group 1, the control, received a basal with no oils, while groups 2 to 7 received a basal diet containing either 1% SO, 1.5% SO, 2% SO, 1% LO, 1.5% LO, or 2% LO, respectively. Quail groups that consumed diets containing LO at all levels showed significantly greater live body weight () at 5th wk of age than other experimental groups. The dietary incorporation of 1.5 or 2% SO or LO at all levels yielded significant improvements in body weight gain () and feed conversion ratio () through 3 to 5 and 1 to 5 wk of age. Different dietary oil sources and levels have no significant impacts on feed intake () and carcass yield parameters. Lipid profile parameters were improved by adding SO and LO in quail diets, with LO having a higher effect than SO. The hepatic and renal functionality were improved by adding SO and LO in quail diets. The lowest uric acid () bloodstream concentrations were recorded in the quail group fed a diet with 2% LO. Values of Gamma globulins () and immunoglobulins (G, M, and A) were increased by adding SO or LO to quail diets. Blood levels of MDA and TAC were improved significantly by including LO in quail diets. The activity of the superoxide dismutase () enzyme was significantly increased by adding SO or LO to quail diets. Generally, adding SO or LO to growing quail diets up to 2% could yield favorable effects on growth performance, blood lipids, hepatic and renal functions, immunity, and antioxidant status; however, LO seems to have better effects than SO.

日粮中添加大豆油和亚麻籽油对日本鹌鹑生长性能、胴体产量和健康状况的影响

多不饱和脂肪酸 ()，包括 n-6 和 n-3 脂肪酸，对于提高家禽的生产性能和健康至关重要。鸟类缺乏内源合成 n-6 和 n-3 脂肪酸的去饱和酶。这项工作旨在确定鹌鹑日粮中添加大豆油 () 和亚麻籽油 () 对生长、血脂、肝肾功能、免疫力和抗氧化状态的影响。总共 350 只日本鹌鹑雏鸡（1 周龄）被随机分为 7 个饲料处理组。根据日本鹌鹑生长的营养需求，制定了7种等热量、等氮的实验基础日粮。第 1 组（对照组）接受不含油的基础饮食，而第 2 至 7 组接受分别含有 1% SO、1.5% SO、2% SO、1% LO、1.5% LO 或 2% LO 的基础饮食。食用含有各种水平 LO 的饮食的鹌鹑组在第 5 周时的活体重 () 显着高于其他实验组。在各个级别的日粮中添加 1.5% 或 2% SO 或 LO 可显着改善 3 至 5 周龄和 1 至 5 周龄的体重增加 () 和饲料转化率 ()。不同的日粮油来源和水平对采食量（）和胴体产量参数没有显着影响。在鹌鹑日粮中添加SO和LO可改善血脂参数，其中LO的效果高于SO。在鹌鹑日粮中添加SO和LO可改善肝肾功能。饲喂 2% LO 饮食的鹌鹑组记录了最低的血流尿酸浓度。通过在鹌鹑日粮中添加 SO 或 LO，γ 球蛋白 () 和免疫球蛋白（G、M 和 A）的值会增加。通过在鹌鹑日粮中添加 LO，MDA 和 TAC 的血液水平得到显着改善。在鹌鹑日粮中添加SO或LO可显着提高超氧化物歧化酶（）的活性。一般来说，在生长鹌鹑日粮中添加SO或LO至2%即可对生长性能、血脂、肝肾功能、免疫力和抗氧化状态产生良好的影响；然而，LO似乎比SO有更好的效果。
