摘要: 试验旨在研究葡萄籽粕对种鸡产蛋高峰后期生产性能、鸡蛋品质及新城疫抗体水平的影响。选取产蛋率、体重相近,健康状态良好的64周龄罗曼灰父母代种鸡810只,随机分为6组,每组5个重复,每个重复27只鸡。对照组饲喂基础日粮,试验组分别饲喂葡萄籽粕替代基础日粮中3%、4.5%、6%、7.5%、9%玉米的试验日粮(分别为试验Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ组)。预试期7 d,正试期30 d。探讨日粮中添加不同水平的葡萄籽粕对种鸡产蛋高峰后期生产性能、鸡蛋品质及新城疫抗体水平的影响及其作用机理。结果表明:葡萄籽粕能够明显抑制种鸡产蛋高峰后期生产性能降低,对于日均产蛋量,试验Ⅲ组极显著高于对照组(P<0.01),试验Ⅰ、Ⅱ组显著高于对照组(P<0.05);试验Ⅰ、Ⅱ、Ⅲ组产蛋率较对照组分别提高了12.38%、14.76%、18.09%(P<0.05),各试验组蛋鸡的日均采食量、料蛋比及破软蛋率与对照组相比差异不显著(P>0.05);葡萄籽粕处理组鸡蛋的哈氏单位、蛋黄重及蛋壳强度均高于对照组,但随葡萄籽粕添加量的增加没有表现出规律性变化;葡萄籽粕能够降低鸡蛋胆固醇含量(P<0.01);并能够提高种鸡新城疫HI抗体水平(P>0.05)。综上,在种鸡产蛋高峰后期日粮中以葡萄籽粕替代玉米,可提高种鸡生产性能和新城疫抗体效价,改善鸡蛋品质,降低鸡蛋中胆固醇含量,且以替代6%的玉米效果较好。

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.
