Effect of Dietary Supplementation with Lactobacillus plantarum on Biochemical Parameter, Immune Cytokines and Cecum Salmonella in Laying Hens Infected with S.enteritidi
摘要
Abstract
The aim of this research was to investigate Lactobacillus plantarum effect on biochemical parameter,plasma immunoglobulin,as well as cecum salmonella copies in laying hens infection salmonella.A total of 400 salmonella-negative,healthy laying hens were randomly divided into 4 groups,each of the two components to 2 biosafety isolated sheds,5 pens of 20 birds each.Dietary treatments were:A:basal diet,B:basal diet+2.0× 108 CFU/g Lactobacillus plantarum,C:basal diet+oral salmonella administration,D:basal diet+2.0× 108 CFU/g Lactobacillus plantarum +oral salmonella administration.All birds (n=200) in C and D were orally challenged with 1 mL suspension of 1.0×108 CFU/mL salmonella at d 7 and d 8 after the initiation of experiment.Group A and B were treated with the same amount of sterile PBS.The results showed as follows:The addition of Lactobacillus plantarum significantly improved (P＜0.05) the total of protein and globulin,and can significantly reduced (P＜0.05) low-density lipoprotein and triglyceride in laying hens infected with salmonella.Lactobacillus plantarum significantly increased (P＜0.05) the plasma of IgM,IgA.During the post-SE-challenge period,Lactobacillus plantarum supplementation reduced (P＜0.05) salmonella copies at D14 and D21.Meanwhile,from d 1 to d 21,the salmonella copies lower of hens supplied with Lactobacillus plantarum (P＜0.05).The addition of Lactobacillus plantarum can maintain the normal biochemical level of hens,alleviate the oxidative stress caused by salmonella infection,and plant Lactobacillus plantarum can reduce the colonization of salmonella in cecum.关键词
