Effects of Rosa sterilis Residue on Production Performance,Egg Quality,Immune Organ Index and Antioxidant Capacity of Hyline Grey Laying Hens
摘要
Abstract
The experiment aimed to study the effects of adding different proportions of Rosa sterilis residue to the diet on the production performance,egg quality,development of immune organs,and antioxidant capacity of laying hens.A total of 400 healthy Hyline gray laying hens aged 390 d were randomly divided into 4 groups,with 5 replicates per group and 20 hens per replicate.The control group was fed a basal diet,while the low,medium,and high dose groups were fed the basal diet supplemented with 3%,5%,and 10%Rosa sterilis residue,respectively.A preliminary trial lasted 1 week,followed by an official trial of 8 weeks.The results showed that:① compared with the control group,both the medium and high dose groups significantly increased the average daily feed intake and egg production rate of the experimental flock(P<0.05),and significantly reduced the feed-to-egg ratio(P<0.05);② the addition of Rosa sterilis residue had no significant effect on egg shape index,eggshell strength,eggshell thickness,yolk index,etc.(P>0.05);compared with the control group,the high dose group significantly improved the yolk color(P<0.05);③ compared with the con-trol group,the spleen index and thymus index of the experimental flock in the medium and high dose groups were significantly increased(P<0.05);④ compared with the control group,the activity of superoxide dis-mutase(SOD)in the serum of the experimental flock in the medium and high dose groups was significantly increased(P<0.05),and the content of malondialdehyde(MDA)was significantly decreased(P<0.05).In conclusion,adding Rosa sterilis residue to the diet can increase the average daily feed intake and egg produc-tion rate of laying hens,reduce the feed-to-egg ratio,enhance antioxidant capacity,improve the production performance of laying hens,and enhance immune ability,with the best effect when adding 10%Rosa sterilis residue.关键词
