Abstract：
The aim of this research was to evaluate the influence of lettuce seed oil (LSO) on the performance, carcass yield, kidney and liver indices, immunity, lipid profile, and cecal microbiota of fattening chicks. A total of 200, 7-day-old Cobb-500 were distributed into 5 experimental groups; each group contained 5 replicates with 8 birds each. The first group 1) the basal diet (only); 2) the basal diet plus lettuce seed oil (0.50 mL/kg); 3) the basal diet plus lettuce seed oil (1.00 mL/kg); 4) the basal diet plus lettuce seed oil (1.50 mL/kg); and 5) the basal diet plus lettuce seed oil (2.00 mL/kg). No significant effect was observed on growth performance, carcass traits, or kidney function at any level of oil. But, liver function was significantly affected due to LSO levels. Serum lipid profiles (total cholesterol-TC, triglyceride-TG, low-density lipoprotein-LDL, and very low-density lipoprotein-VLDL) were significantly reduced by using LSO levels compared to the control group. Dietary LSO significantly increased immunological and antioxidant parameters, except for malondialdehyde-MDA, which was reduced. On the other hand, the cecal microbiota was significantly improved by LSO additives. It was concluded that the dietary supplementation of LSO had beneficial effects on liver and kidney functions, lipid profile, immunity, antioxidant parameters, and the bacteriology of fattening chicks.
摘要：
这项研究的目的是评估生菜籽油（LSO）对性能的影响，car体产量，肾脏和肝脏指数，豁免权,血脂谱,和育肥雏鸡的盲肠微生物群。将总共200个7天龄的Cobb-500分配到5个实验组中；每组包含5个重复，每个8只鸟。第一组1）基础日粮（仅）；2）基础日粮加生菜籽油（0.50mL/kg）；3）基础日粮加生菜籽油（1.00mL/kg）；4）基础日粮加生菜籽油（1.50mL/kg）；5）基础日粮加生菜籽油（2.00mL/kg）。对生长性能没有显著影响，car体性状，或肾功能在任何水平的油。但是,由于LSO水平，肝功能受到显着影响。血脂谱（总胆固醇-TC，甘油三酯-TG，低密度脂蛋白LDL，与对照组相比，使用LSO水平显着降低了极低密度脂蛋白-VLDL）。饮食LSO显着增加免疫和抗氧化参数，除了丙二醛-MDA，减少了。另一方面,LSO添加剂显著改善了盲肠微生物群。结论膳食补充LSO对肝肾功能有有益作用,血脂谱,豁免权,抗氧化剂参数，和育肥小鸡的细菌学。
