【摘要】：为研究植物甾醇对肉鸡生长性能、血液生化指标的影响,试验将1600羽1日龄AA肉鸡随机分为4组,每组4个重复,分别为对照组、10、20 mg/kg和40 mg/kg植物甾醇添加组。结果表明:与对照组相比,20 mg/kg植物甾醇添加组在生长前期(1~21 d)和生长后期(22~42 d),肉鸡平均日增重(ADG)分别提高5.92%和4.26%(P0.05);生长后期(22~42 d)料肉比(F/G)降低4.48%(P0.05)。从血液生化指标来看,20 mg/kg和40 mg/kg植物甾醇添加组血清总胆固醇(TC)含量分别较对照组降低11.92%和11.57%(P0.05);40 mg/kg植物甾醇添加组血清低密度脂蛋白胆固醇(LDL-C)含量较对照组降低17.71%(P0.05);10、20、40 mg/kg植物甾醇添加组总超氧化物歧化酶(T-SOD)活性较对照组分别提高12.05%、6.16%和8.43%(P0.05);谷胱甘肽过氧化物酶(GSH-Px)活性则有所提高(P0.05)。根据本次试验结果,肉鸡日粮中添加植物甾醇可以提高生产性能,降低血清胆固醇水平,增强血清抗氧化能力。植物甾醇最佳添加水平为20 mg/kg。
[Abstract]:In order to study the effects of phytosterol on growth performance and blood biochemical indexes of broilers, 1600 1-day-old AA broilers were randomly divided into 4 groups, each group with 4 repeats, 10 mg/kg and 40 mg/kg phytosterol supplementation group, respectively. The results showed that the average daily gain of broilers increased 5.92% and 4.26% respectively in the 20 mg/kg phytosterol supplementation group at the early stage of growth (21 days) and the later stage of growth (22 ~ 42 d), and the average daily gain of the broilers was decreased by 4.48% and 4.48% (P 0.05), respectively, compared with that of the control group at the later stage of growth. In terms of blood biochemical indexes, the serum total cholesterol (TC) levels in the 20 mg/kg and 40 mg/kg phytosterol supplementation groups were 11.92% and 11.57% lower than those in the control group, respectively, and the serum low density lipoprotein cholesterol (LDL-C) content in the phytosterol supplemented group was 17.71% lower than that in the control group. The total superoxide dismutase (T-SOD) activity of mg/kg supplemented with phytosterol was increased by 6.16% and 8.43%, respectively, and the activity of glutathione peroxidase (GSH-Px) was increased by 6.05% and 8.43%, respectively, and the activity of glutathione peroxidase (GSH-Px) was also increased. According to the results of this experiment, adding phytosterol to the diet of broilers can improve the production performance, reduce the level of serum cholesterol and enhance the antioxidation ability of serum. The optimum addition level of phytosterol was 20 mg / kg.
