灵芝粉对产蛋后期蛋鸡生产性能、蛋品质以及肠道健康的影响
Effects of Ganoderma Lucidum Powder on Production Performance,Egg Quality and Intestinal Health of Laying Hens at the Later Laying Stage
摘要
Abstract
The experiment aimed to study the effects of Ganoderma lucidum powder on the production performance,egg quality and intestinal health of laying hens at the later stage of laying.A total of 120 lay-ing hens at 60 weeks of age,with similar body condition and no disease,were selected and randomly divid-ed into 2 groups with 5 replicates(n=12)per group.The experimental lasted for 60 days.The control group was fed with basal diet,and the Ganoderma lucidum group was added 1.5％Ganoderma lucidum in the basal diet.The results showed that compared with the control group:(1)the Ganoderma lucidum group showed a significant increase in egg production rate and egg qualification rate(P＜0.05),while the average daily feed intake,soft-shelled egg rate,shell-broken egg rate,and feed-to-egg ratio were signifi-cantly reduced(P＜0.05);(2)the content of crude protein,vitamin A,vitamin E,calcium,iron and zinc in the eggs from the Ganoderma group was significantly increased(P＜0.05);(3)the levels of flavor-ami-no acids in the eggs of the Ganoderma group increased by 3.49％(P＜0.05),the content of non-essential amino acids increased by 3.29％(P＜0.05).Unsaturated fatty acid contents were significantly higher(P＜0.05);(4)the height of duodenal villi of the hens in the Ganoderma lucidum group increased by 42.39％(P＜0.05),while the depth of crypts decreased by 11.09％(P＜0.05).The velvet to crypt ratio increased significantly(P＜0.05).Additionally,the number of Proteobacteria phylum in the cecal microbiota of the hens in the Ganoderma group significantly increased(P＜0.05),while the number of Actinobacterium phylum significantly decreased(P＜0.05).The numbers of genus Rikenellaceae_RC9_gut_group,Bacte-roidales_unclassified,Subdoligranulum were significantly higher(P＜0.05).In conclusion,the addition of Ganoderma lucidum powder to diets can significantly enhance the production performance of laying hens,improve egg quality and nutritional composition,and regulate the intestinal morphology and benefi-cial bacterial communities in the cecum.关键词
