Abstract:

The experimtent was conducted to investigate the effects of water extraction of Moringa oleifera and Morinda citrifolia (LNS) on performance and egg quality of Hyline Brown laying hens.A total of 540 Hyline Brown laying hens at peak period of laying eggs (22 weeks) were randomly allocated into 6 groups with 6 replicates per group and 15 laying hens per replicate.The hens in negative control group(NC)were fed a corn-soybean meal basal diet,in positive control group (PC) were fed the basal diet supplemented with 50 mg/kg zinc bacitracin,and the others in the experimental groups were fed the basal diet supplemented with 0.25,0.50,0.75 and 1.00 g/kg LNS,respectively.The experiment lasted for 24 weeks.The results showed as follows:①Different diet treatments had no significant effects on the production performance in the earlier and later stages(P>0.05),while the diets supplemented with 0.50 and 0.75 g/kg LNS had the tendency to improve the ratio of feed to egg in the later period of the experiment(P=0.087);Diet treatments had no significant effects on shape index,egg strength,shell thickness,yolk weight and haugh unit(P>0.05).However,diet supplemented with zinc bacitracin and LNS had the tendency to improve the egg strength(P=0.062).②Compared to NC and PC groups,diets supplemented with LNS significantly improved eggshell color of raw and boiled egg yolk (P<0.05),and significantly decreased egg yolk cholesterol content (except 0.25 LNS group)(P<0.05).③Compared to NC group,diet supplemented with 0.50 g/kg LNS had significantly increased egg contents of total flavonoids,docose hexaenoie acid (DHA),lecithin,linolenic acid and linoleic acid (P<0.05).In conclusion,as feed additive,LNS could improve egg's nutritional quality,and the dietary suitable supplementation of LNS for laying hens was 0.25 to 0.50 g/kg.
