摘    要:为研究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,本试验选用400只沙门氏菌阴性蛋鸡,随机分成4个处理组,每处理组5个重复,每个重复20只试鸡。试验第1周,对照组(T1、T3组)饲喂基础日粮,试验组(T2、T4组)在基础日粮添加2×108 CFU/g植物乳酸杆菌。饲喂1周后,T3、T4组试鸡连续2 d灌服1 mL肠炎沙门氏菌悬浮液(1.0×108 CFU/mL),T1、T2组试验鸡口服等量无菌PBS溶液。结果显示:①蛋鸡感染肠炎沙门氏菌后可极显著降低产蛋率(PSE=0.02)及平均日采食量(PSE=0.01)。添加植物乳酸杆菌可显著提高产蛋率(PLP=0.02),显著降低料蛋比(PLP=0.04)。②蛋鸡感染肠炎沙门氏菌后,添加植物乳酸杆菌可显著增加蛋壳厚度(PLP=0.01)和蛋壳强度(PLP=0.02),显著降低蛋黄颜色(PLP=0.02)。③蛋鸡感染肠炎沙门氏菌后可极显著提高蛋鸡血浆中碱性磷酸酶(ALP)含量(PSE<0.01),植物乳酸杆菌干预可显著提高谷草转氨酶(AST)(PLP=0.02)、钙(PLP=0.04)和磷(PLP=0.04)的含量。综上所述,植物乳酸杆菌可显著改善蛋鸡生产性能和蛋品质,维持蛋鸡生理生化指标稳定,同时可缓解沙门氏菌带来的病理损伤,保障蛋鸡机体健康。

关 键 词:植物乳酸杆菌  蛋鸡  肠炎沙门氏菌  生产性能  蛋品质

Abstract:The aim of this research was to assess the effect of Lactobacillus plantarum on production performance,egg quality and plasma biochemical parameter in laying hens infected with Salmonella Enteritidis.A total of 400 Salmonella-negative laying hens were chosen and randomly assigned 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 2.0×108 CFU/g Lactobacillus plantarum.And then laying hens in groups T3 and T4 were orally challenged with 1 mL suspension of 1.0×108 CFU/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 significantly decreased,and adding Lactobacillus plantarum could significantly increase the laying rate (PLP=0.02) and decrease feed/egg (PLP=0.04).②Lactobacillus plantarum 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.③The ALP was extremely significantly increased in laying hens infected with Salmonella Enteritidis(PSE<0.01),whereas Lactobacillus plantarum supplementation could significantly increase AST (PLP=0.02),Ca (PLP=0.04) and P (PLP=0.04) contents.In conclusion,dietary supplement with Lactobacillus plantarum could improve growth performance of hens,and alleviate damages caused by Salmonella Enteritidis,which gave an insight in improving laying hens health.
Keywords:Lactobacillus plantarum  laying hens  Salmonella Enteritidis  production performance  egg quality
