Effects of Lactobacillus plantarum on Production Performance, Egg and Feces Bacteria content of Salmonella enteric-Infected Hens
摘要
Abstract
The experiment was conducted to study the influence of Lactobacillus plantarum (LP) on production performance,egg and feces Salmonella enteric (SE) residues of SE-infected hens.144 fifty-week-old Nongda No.3 hens were randomly allocated to 4 treatments with 4 replicates of 9 hens each.The hens in blank control and positive control groups were fed the basal diet,terramycin group,the basal diet with terramycin (5 mg/kg),LP group,the basal diet with Lactobacillus plantarum (109CFU/kg).The hens in positive control,terramycin and LP groups were oral inoculated with 1 mL SE (109CFU/mL) on 22 and 24 d.The experiment lasted for 50 d.Before being vaccinated,the production performance of each group showed no significant difference (P>0.05);After being vaccinated,in early period,compared with blank control group,the average egg weight significantly decreased (P<0.05),the feed-egg ratio significantly increased (P<0.05),and the SE content of eggs and feces significantly increased (P<0.05) in positive control group.Compared with positive control group,the average egg weight in terramycin group and LP group increased by 5.43% and 9.64% respectively (P<0.05),while the feed-egg ratio decreased by 11.51% (P<0.05) and 5.16% (P>0.05) respectively.In later period,the feedegg ratio in LP group decreased by 9.96% (P<0.05),SE content of eggs and feces in LP group decreased by 43.17% and 23.93% respectively (P<0.05).The production performance and E.coli,SE-carrying rates of eggs had no significant difference among the blank control,LP and terramycin groups (P>0.05).The results indicated that,supplemented with Lactobacillus plantarum or terramycin could improve the production performance,reduce the SE content in eggs and feces,and improve the ability to resist infection in hens.Because Lactobacillus plantarum had the characteristics of no pollution and no residue,it could be used as a kind of ideal substitute for antibiotics in poultry production.关键词
