本研究评估了欧芹精油对肉鸡生长性能的影响。胎体特征,肝肾功能,免疫力和抗氧化活性,和脂质分布。将总共160只无性别的7天肉鸡(Cobb500)分为五组;每组包含五个重复,每个重复八只鸟。治疗方法为(1)基础饮食(无添加剂,T1),(2)基础日粮+0.5mL欧芹精油/kg(T2),(3)基础日粮+1mL欧芹精油/kg(T3),(4)基础日粮+1.5mL欧芹精油/kg(T4),和(5)基础饮食2mL欧芹精油/kg(T5)。根据GC-MS分析,欧芹油含有D-柠檬烯,十六烷酸,α-环二尖瓣,globulol,α-pine烯,Myristicin,冰草烯,Bergapten,α-chamigrene,等。目前的结果表明,欧芹油中最丰富的分子是D-柠檬烯(18.82%),油酸(14.52%),α-环二尖瓣(11.75%),格布洛尔(11.24%),α-愈创烯(7.34%),piol(5.45%),和十六烷酸(4.69%)。在1-3周龄期间,向肉鸡饮食中添加欧芹精油会增加体重(BW)。与其他处理和对照组相比,T5组记录的BW值最高(869.37g)。胆固醇,甘油三酯,低密度脂蛋白(LDL)胆固醇,和总免疫球蛋白,饲喂欧芹精油的鸟类中包括免疫球蛋白G(IgG)和免疫球蛋白M(IgM)的水平均未受到影响。与对照组和其他处理相比,T3组记录的超氧化物歧化酶(SOD)的最高值(159ng/mL)和丙二醛(MDA)的最低值(2.01ng/mL)。总之,我们建议使用欧芹油的水平为1毫升/千克肉鸡的饮食。
The current study evaluated the effects of parsley essential oil on broiler growth performance, carcass features, liver and kidney functions, immunity and antioxidant activity, and lipid profile. A total of 160 unsexed 7-day broiler chicks (Cobb500) were distributed into five groups; each group contained five replicates with eight birds each. The treatments were (1) basal diet (no additive, T1), (2) basal diet + 0.5 mL parsley essential oil/kg (T2), (3) basal diet + 1 mL parsley essential oil/kg (T3), (4) basal diet + 1.5 mL parsley essential oil/kg (T4), and (5) basal diet + 2 mL parsley essential oil/kg (T5). According to GC-MS analysis, parsley oil contains D-limonene, hexadecanoic acid, α-cyclocitral, globulol, α-pinene, myristicin, cryophyllene, bergapten, α-chamigrene, etc. The current results indicated that the most abundant molecules in parsley oil were D-limonene (18.82%), oleic acid (14.52%), α-cyclocitral (11.75%), globulol (11.24%), α-guaiene (7.34%), apiol (5.45%), and hexadecanoic acid (4.69%). Adding parsley essential oil to the broiler diet quadratically increased body weight (BW) during 1-3 weeks of age. The T5 group recorded the highest value (869.37 g) of BW in comparison to other treatments and the control group. The cholesterol, triglyceride, low-density lipoprotein (LDL) cholesterol, and total immunoglobulin, including immunoglobulin G (IgG) and immunoglobulin M (IgM) levels in the birds fed parsley essential oil were not affected. The T3 group recorded the highest value (159 ng/mL) of superoxide dismutase (SOD) and the lowest value (2.01 ng/mL) of malondialdehyde (MDA) when compared to the control and other treatment. In conclusion, we recommend using parsley oil at levels of 1 mL/kg diet of broiler chicks.
