摘要
试验旨在研究复合金银花提取物对蛋鸡血清抗氧化、蛋品质及风味的影响。试验选取1552只健康400日龄的京粉6号蛋鸡,随机分为2组,每组4个重复,每个重复194只鸡。对照组饲喂基础饲粮,试验组在基础饲粮中额外添加0.3%复合金银花提取物。预试期7 d,正式试验期56 d。结果显示,两组蛋鸡的生产性能无显著差异(P>0.05),试验组鸡蛋的哈氏单位极显著高于对照组(P<0.01)。与对照组相比,试验组血清中丙二醛(MDA)含量显著降低(P<0.05),谷胱甘肽过氧化物酶(GSH-Px)活性极显著增强(P<0.01)。试验组蛋清中的丝氨酸、蛋氨酸和精氨酸含量显著高于对照组(P<0.05),异亮氨酸含量显著低于对照组(P<0.05)。试验组蛋黄中饱和脂肪酸、不饱和脂肪酸、单不饱和脂肪酸含量显著高于对照组(P<0.05),脂肪酸总量极显著高于对照组(P<0.01)。试验组的蛋黄挥发性物质数量和醛类物质含量均高于对照组。研究表明,饲粮中添加0.3%复合金银花提取物可以提高蛋鸡机体抗氧化能力和蛋品质,影响蛋黄中挥发物质含量,提高鸡蛋食用口感。
The experiment aimed to study the effects of compound honeysuckle extract on the antioxidant capacity,egg quality,and flavor of laying hens.A total of 1552 healthy 400-day-old Jingfen No.6 laying hens were randomly divided into two groups,with four replicates per group,each containing 194 laying hens.The control group was fed a basic diet,while the experimental group was supplemented with 0.3%compound honeysuckle extract in the basic diet.The pre-trial period lasted for seven days and the formal experimental period lasted for 56 days.The results showed that there is no significant difference in production performance between the two groups(P>0.05),but the experimental group's egg Haugh units were extremely higher than those of the control group(P<0.01).Compared to the control group,the experimental group had significantly lower levels of malondialdehyde(MDA)in the serum(P<0.05)and extremely higher activity of glutathione peroxidase(GSH-Px)(P<0.01).The concentrations of serine,methionine,and arginine in egg white of experimental group were significantly higher than those of control group(P<0.05),and the content of isoleucine was significantly lower than that of control group(P<0.05).The experimental group's egg yolks had significantly higher levels of saturated fatty acids,unsaturated fatty acids,and monounsaturated fatty acids than the control group(P<0.05),and the total fatty acid was extremely higher(P<0.01).The types of yolk volatile substances and aldehyde content in experimental group were higher than those in control group.The study indicates that adding 0.3%compound honeysuckle extract to the feed can improve the antioxidant capacity of the laying hens and the quality of the eggs,affect the content of volatile substances in the egg yolk,and enhance the taste of the eggs.
