This study was undertaken to investigate the effects of supplementation of probiotic strain Lactobacillus plantarum TN8 encapsulated in sodium alginate-chitosan or a commercial blend of essential oils on total cholesterol, High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL) and growth performance of broiler chickens. The results showed that the broiler chickens supplemented with encapsulated L. plantarum TN8 or essential oil has a higher growth than the control group. After 35days, the weight means were 1860 and 1880g respectively in dietary supplementation with probiotic or essential oil, while they are 1800g in the control group. The evolution of the feed consumption and feed conversion per week showed that the supplementation of encapsulated TN8 strain or essential oil in broiler chickens food has a positive influence on their appetite. Similarly, supplementation of the feed with this encapsulated strain significantly reduced the rate of cholesterol (HDL and LDL) as well as the contents of triglycerides in broiler chickens. Through our study, it appears that the use of the probiotic supplementation or essential oil to broilers were found to be better than the control group of chickens, resulting in a significant economic impact and promoting effect on health.
本研究旨在探讨用海藻酸钠-壳聚糖包被的植物乳杆菌 TN8 或商业混合精油对肉鸡总胆固醇、高密度脂蛋白（HDL）、低密度脂蛋白（LDL）和生长性能的影响。结果表明，补充包被的 L. plantarum TN8 或精油的肉鸡比对照组生长更快。35 天后，在添加益生菌或精油的饮食中，体重平均值分别为 1860 和 1880g，而对照组为 1800g。每周饲料消耗和饲料转化率的变化表明，在肉鸡饲料中添加包被的 TN8 菌株或精油对其食欲有积极影响。同样，在饲料中添加这种包被的菌株显著降低了肉鸡的胆固醇（HDL 和 LDL）和甘油三酯含量。通过我们的研究，似乎使用益生菌补充剂或精油对肉鸡的效果比对照组的鸡更好，对健康产生了显著的经济影响和促进作用。
