摘要
试验旨在研究饲粮中添加花椒籽对蛋鸡生产性能、血清指标和蛋品质的影响。试验选择42周龄的京粉6号蛋鸡360只,随机分为2组,每组6个重复,每个重复30只。对照组(CON组)饲喂基础饲粮,试验组(ZBMS组)饲喂使用2%花椒籽替代基础饲粮中的玉米的饲粮。预试期7 d,正式试验期28 d。结果显示:与CON组相比,ZBMS组第1~14、15~28、1~28 d的平均蛋重显著提高(P<0.05),软破蛋率显著降低(P<0.05);ZBMS组蛋鸡血清谷草转氨酶(AST)活性及白细胞介素-1β(IL-1β)、干扰素-γ(IFN-γ)水平均显著降低(P<0.05),白细胞介素-4(IL-4)水平、总抗氧化能力(T-AOC)均显著提高(P<0.05)。与CON组相比,ZBMS组第28 d时的蛋黄色泽显著提高(P<0.05);ZBMS组鸡蛋中棕榈油酸、亚油酸、α-亚麻酸、山嵛酸和二十二碳六烯酸(DHA)的含量均显著提高(P<0.05),肉豆蔻酸、十七碳酸、硬脂酸、反油酸、油酸、二十碳一烯酸、附子酯酸和花生三烯酸的含量均显著降低(P<0.05)。研究表明,使用2%花椒籽替代玉米可增强蛋鸡免疫力和抗氧化能力,提高蛋重,降低软破蛋率,提升蛋黄色泽和蛋黄比率,增加鸡蛋中多不饱和脂肪酸的含量。
This experiment aimed to investigate the effects of adding Zanthoxylum bungeanum Maxim seeds to feed on the production performance,serum indicators,and egg quality of laying hens.The experiment involved selecting 360 Jingfen No.6 hens at the age of 42 weeks,which were randomly divided into two groups,with six replicates per group,and 30 hens in each replicate.The control group(CON group)was fed basic feed,while the experimental group(ZBMS group)was fed a diet in which 2% Zanthoxylum bungeanum Maxim seeds were used to replace corn in the basic feed.The pre trial period was seven days,and the formal trial period was 28 days.The results showed that compared with CON group,the average egg weight from 1 to 14,15 to 28 and 1 to 28 days in ZBMS group was significantly increased(P<0.05),and the soft broken egg rate was significantly decreased(P<0.05).Serum glutamic oxalacetic transaminase(AST)activity,interleukin-1β(IL-1β)and interferonγ(IFN-γ)levels of laying hens in ZBMS group were significantly decreased(P<0.05),while serum interleukin-4(IL-4)level and total antioxidant capacity(T-AOC)were significantly increased(P<0.05).Compared with CON group,yolk color in ZBMS group at 28 day was significantly increased(P<0.05).Compared with CON group,the contents of palmitoleic acid,linoleic acid,α-linolenic acid,behenic acid and docosahexaenoic acid(DHA)of eggs in ZBMS group were significantly increased(P<0.05),while the contents of myristic acid,heptadeconic acid,stearic acid,oleic acid,eicosanoenoic acid,aconite acid and arachidonic acid were significantly decreased(P<0.05).The study indicates that using 2%Zanthoxylum bungeanum Maxim seeds to replace corn can enhance the immunity and antioxidant capacity of laying hens,increase egg weight,reduce soft break rate,improve egg yolk color and yolk ratio,and increase the content of polyunsaturated fatty acids in eggs.
