Effect Of Fermented Moringa On Growth Performance,Meat Quality And Intestinal Health Of Broilers

The research shows that Moringa oleifera is rich in nutrients.The appropriate addition of Moringa oleifera instead of some conventional raw materials in animal diet can improve animal growth performance,intestinal health,improve body immunity,and have no adverse effects on animal body;Fresh Moringa oleifera contains high anti nutritional factors and special pungent smell,which affects the palatability of animals,so it is difficult to promote its application in practical production.In this experiment,Moringa oleifera was crushed for solid-state fermentation to study the effects of different gradients of fermented Moringa oleifera on the growth performance,meat quality and intestinal health of broilers,To explore the optimal addition amount of fermented Moringa in broiler diets,which can be used as a reference to develop Moringa resources to replace conventional feed materials,is of great significance in alleviating the shortage of feed resources in China.A total of 360 45-day-old broilers with similar health status were randomly divided into 4 treatment groups,with 6 replicates in each group and 15 chickens in each replicate,each replication 1 cage.The basal diet was used as the blank control group,and experimental groups A,B and C were supplemented with10%,14% and 18% fermented moringa oleifera in the basal diet,respectively,Formal recording of data trials 49 D.The results showed that:1.Growth performance,meat quality,dressing percentage and others:(1)Growth performance: The final weight and daily gain increased in dose effect,but the difference was not significant(P > 0.05);it had no effect on feed-meat ratio and feed intake.(2)Body size: The tibia length(P < 0.01),chest width and back width(P < 0.05)were significantly increased.(3)Slaughter indexes: There was no effect on slaughter weight indexes and dressing percentage(P > 0.05).Organ index: It had no effect on organ indexes(P > 0.05),but significantly increased heart weight and testicular weight(P < 0.05).(4)Meat quality:A group could significantly reduce the shearing force of meat(P < 0.05),but there were no significant differences in OD and p H value among the groups(P >0.05).2.Serum biochemical indexes:(1)Serum protein: Compared with other experimental groups,the total protein and globulin of 14% group were the highest,and the ratio of albumin to white globule was the lowest,but there was no significant difference among all groups in all serum protein detection items(P > 0.05).(2)Serum enzyme activity: Compared with the control group,each index has different effects,but the difference is not significant(P > 0.05).(3)Serum lipid metabolism: The content of triglyceride(TG)in 14% group was significantly decreased(P < 0.05),but there was no significant difference in other indexes(P > 0.05).(4)Immunoglobulins: Serum Ig G,Ig A and Ig M had no significant effect(P > 0.05).3.Intestinal morphology:(1)Intestinal length: Compared with the control group,the length of duodenum in Group A,B and C was significantly increased(P < 0.05),but there were no significant differences in jejunum and ileum(P >0.05).(2)Height of intestinal villus: Duodenum,jejunum and ileum showed an increasing trend(P > 0.05),which was related to the supplemental level.(3)Crypt depth: It had different influence on the recess depth of each intestinal tract(P > 0.05).4.Intestinal microorganisms:(1)Phylum level: Firmicutes is the first dominant phylum in each group,and Bacteroidetes is the second dominant phylum in each group,and the proportion of the above two phyla in each group has no significant difference(P > 0.05).The(F/B,Firmicutes/Bacteroidetes)values of each group were 1.37,1.24,1.16 and 1.15,respectively.The relative abundance of Synergistetes increased(P > 0.05)in a dose-dependent manner.The relative abundance of Cyanobacteria decreased(P > 0.05),showing dose effect.(2)Genus level: Bacteroides is the first dominant genus in each group,and its relative abundance has an upward trend(P > 0.05),showing dose effect;Faecalibacterium is the second dominant phylum in each group,and the relative abundance in groups A,B and C was lower than that in control group(P > 0.05).Conclusion: Fermented Moringa has some effects on growth performance,dressing percentage,meat quality and serum biochemical indexes of broilers compared with the control group,but the difference is not significant.However,it can improve the development of tibia,improve the skeleton of broilers,and improve the intestinal health of broilers to a certain extent.Under the experimental conditions,the effect of 14-18% addition is better than that of control group and 10% group.
