摘要:

本试验旨在研究日粮中添加辣诺素(辣木和诺丽果的提取物)对蛋鸡生产性能及蛋品质的影响。将产蛋高峰期(22周龄)的海兰褐商品蛋鸡540只随机分为6个处理,每个处理6个重复,每个重复15只鸡。负对照组(NC)饲喂基础日粮,正对照组(PC)饲喂添加50 mg/kg杆菌肽锌的基础日粮,4个试验组分别饲喂添加0.25、0.50、0.75和1.00 g/kg辣诺素(LNS)的基础日粮。试验期24周。结果显示:①日粮处理对蛋鸡试验前期和后期生产性能均无显著影响(P>0.05),试验后期添加0.50和0.75 g/kg辣诺素有改善料蛋比的趋势(P=0.087);日粮处理对试验前期和后期鸡蛋蛋形指数、蛋壳强度、蛋壳厚度、蛋黄重和哈氏单位均无显著影响(P>0.05),但日粮中添加杆菌肽锌和辣诺素有提高蛋壳强度的趋势(P=0.062),其中以添加0.75g/kg辣诺素组鸡蛋强度最高。②与正、负对照组相比,添加辣诺素显著增加了生蛋黄和熟蛋黄的罗氏蛋黄色比率(P<0.05),显著降低了蛋黄胆固醇的含量(0.25 LNS组除外)(P<0.05)。③与负对照组相比,添加0.50 g/kg辣诺素显著提高了鸡蛋总黄酮、二十二碳六烯酸(DHA)、卵磷脂、亚麻酸和亚油酸含量(P<0.05)。综合以上试验结果,辣诺素作为饲料添加剂具有提高鸡蛋营养品质的功能,考虑到添加成本,产蛋鸡日粮中添加0.25~0.50 g/kg为宜。

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.
