包被丁酸钠-DHA对蛋鸡生产性能、蛋品质及鸡蛋DHA富集的影响
Effect of coated sodium butyrate-DHA on production performance,egg quality,and egg DHA enrichment of laying hens
摘要
Abstract
The experiment aimed to investigate the effects of adding coated sodium butyrate-docosahexaenoic acid(DHA)to the diet on the production performance,egg quality,egg DHA enrichment level,shelf life,and economic benefits of Roman laying hens.A total of 600 healthy 350-day-old Roman laying hens were randomly divided into two groups with 10 replicates per group and 30 hens per replicate.The control group was fed a basal diet,while the experimental group was fed with 2.5%coated sodium butyrate DHA(sodium butyrate content of 30%,DHA purity≥10%)in the basic feed.The pre-test period lasted for seven days,and the formal test period was 40 days.The results showed that compared with the control group,the average daily feed intake and egg production rate of laying hens in the experimental group slightly increased,the feed-to-egg ratio slightly decreased,but there were no significant differences(P>0.05).The egg DHA content in the experimental group reached 295.57 mg/100 g,which was extremely increased by 396.00%(P<0.01).The crude fat content,eggshell strength,and eggshell thickness were extremely increased by 20.00%,30.62%,and 13.51%respectively(P<0.01).The shelf life of eggs stored at room temperature(25±1)℃in the experimental group was significantly prolonged by 80.00%(P<0.05),and the shelf life of eggs stored at refrigerated temperature(4±1)℃was significantly prolonged by 40.00%(P<0.05).The economic benefits of the experimental group reached 12.92 yuan/kg,with an input-output ratio of 1.00∶3.40,which was better than the control group.The study shows that adding 2.5%coated sodium butyrate DHA in feed can efficiently enrich egg DHA,directionally improve egg quality,extend shelf life,without affecting the production performance of laying hens.关键词
