Abstract: The purpose of this experiment was to study the effects of grape seed meal on egg production performance,egg quality and Newcastle disease antibody level of breeder chickens during the late laying peak period.810 64-week-old Roman grey parents breeders with similar laying rate and body weight were randomly divided into 6 groups with 5 replicates in each group and 27 chickens in each replicate.The control group was fed with basic diet,while the experimental group was fed with grape seed meal instead of corn in the basic diet,which was 3%,4.5%,6%,7.5% and 9% respectively (the experimental group Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ).The preliminary period is 7 days and the positive period was 30 days.The effects of different levels of grape seed meal on egg production performance,egg quality and Newcastle disease antibody level of breeder chickens at the later stage of peak laying were studied.The results showed that grape seed meal could significantly inhibit the decline of egg production performance in the late peak period of laying hens,and the average daily egg production traits in group Ⅲ were significantly higher than those in control group (P<0.01),while those in group Ⅰ and Ⅱ were significantly higher than those in control group (P<0.05).In the daily average egg production traits,the experimental group Ⅲ was significantly higher than the control group (P<0.01),and the experimental group Ⅰ and Ⅱ were significantly higher than the control group (P<0.05).In terms of laying rate traits,the experimental group Ⅰ,Ⅱ and Ⅲ increased by 12.38%,14.76% (P<0.05),18.09% (P<0.01) respectively compared with the control group.The average daily feed intake,feed-egg ratio and breaking soft egg rate of the experimental group were not significantly different from those of the control group (P>0.05).Harrington's unit,yolk weight and eggshell strength of the grape seed meal treatment group were higher than those of the control group,but there was no regular change with the increase of grape seed meal content.Grape seed meal could decrease the cholesterol content of eggs (P<0.01),and grape seed meal could increase the HI antibody level of breeder chickens (P>0.05).To sum up,replacing corn with grape seed meal in the diet of breeder chickens at the later stage of egg laying peak could improve the performance of breeder chickens and the titer of Newcastle disease antibody,improve the quality of eggs,reduce the cholesterol content in eggs,and the replacement of 6% corn was better.
