Effects of supplementation with L. plantarum TN8 encapsulated in alginate-chitosan in broiler chickens

•Effects of addition of TN8 strain encapsulated in alginate-chitosan or essential oil on blood parameters and growth performance in broiler.•Supplementation of the feed with this strain reduced cholesterol rate (HDL and LDL) as well as the contents of TG in broiler.•Oral administration of immobilized TN8 strain or essential oil has a higher growth than control group.•Evolution of feed consumption and feed conversion showed that supplementation of TN8 strain has a positive influence on broilers appetite.

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 35 days, the weight means were 1860 and 1880 g respectively in dietary supplementation with probiotic or essential oil, while they are 1800 g 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.
