植物乳酸杆菌对感染肠炎沙门氏菌蛋鸡生产性能、蛋品质及血浆生化指标的影响
Effect of Dietary Supplement with Lactobacillus plantarum on Production Performance, Egg Quality,Plasma Biochemical Parameters in Laying Hens Infected with Salmonella Enteritidis
摘要
Abstract
The aim of this research was to assess the effect of Lactobacillus plantarum on produc-tion performance,egg quality and plasma biochemical parameter in laying hens infected with Sal-monella Enteritidis.A total of 400 Salmonella-negative laying hens were chosen and randomly as-signed to 4 treatments with 5 replicates per treatment and 20 hens per replicate.At the first week of the experiment,the laying hens in groups T1 and T3 were fed basal diet,that in groups T2 and T4 were fed basal diet supplement with 2.0×108CFU/g Lactobacillus plantarum.And then lay-ing hens in groups T3 and T4 were orally challenged with 1 mL suspension of 1.0×108CFU/mL Salmonella Enteritidis for 2 consecutive days,while the hens in other two groups were orally challenged with 1 mL PBS.The results showed that:①The laying rate(PSE=0.02)and average daily feed intake(PSE=0.01)of laying hens infected with Salmonella Enteritidis were signifi-cantly decreased,and adding L actobacillus p lantarum could significantly increase the laying rate (PLP= 0.02)and decrease feed/egg(PLP= 0.04).② L actobacillus p lantarum supplementation significantly increased eggshell thickness(PLP= 0.01)and eggshell strength(PLP= 0.02),and significantly reduced yolk color(PLP= 0.02)of laying hens infected Salmonella Enteritidis.③ The ALP was extremely significantly increased in laying hens infected with Salmonella Enterit-idis(PSE<0.01),w hereas L actobacillus p lantarum supplementation could significantly increase AST(PLP=0.02),Ca(PLP=0.04)and P(PLP=0.04)contents.In conclusion,dietary supple-ment with Lactobacillus plantarum could improve growth performance of hens,and alleviate dam-ages caused by Salmonella Enteritidis,which gave an insight in improving laying hens health.关键词
