摘　　要：本试验旨在探究薄荷叶粉对产蛋后期蛋鸡生产性能和鸡蛋营养成分的影响。选取产蛋后期产蛋率[(64.37±3.24)%]相近的新杨黑羽蛋鸡216只,随机分为4组,其中对照组饲喂基础饲粮,另外3组分别在基础饲粮中添加0.1%、0.2%和0.4%的薄荷叶粉,每组9个重复,每个重复6只鸡。整个试验期为35 d,其中预试期为7 d,正试期为28 d。结果显示:1)与对照组相比,饲粮中添加薄荷叶粉对产蛋后期蛋鸡的平均日采食量(ADFI)、料蛋比、产蛋率和蛋重均无显著影响(P>0.05);同时,3个试验组蛋鸡血清中免疫球蛋白G(IgG)和总蛋白(TP)含量显著增加(P<0.05);饲粮中添加0.1%薄荷叶粉显著增加卵巢中大白卵泡数(P<0.05)。2)与对照组相比,饲粮中添加薄荷叶粉可显著提高鸡蛋的蛋壳强度(P<0.05),改善蛋形指数;同时有增加蛋清中L-苯丙氨酸、L-色氨酸、L-异亮氨酸和总必需氨基酸含量的趋势(0.05<P<0.10);添加0.1%和0.4%薄荷叶粉对蛋黄脂肪酸含量无显著影响(P>0.05)。综上可知,饲粮中添加0.1%和0.4%薄荷叶粉在不影响蛋鸡生产性能的同时,可提高蛋鸡血清中IgG和TP含量,具有增强蛋鸡免疫力的潜力,同时可改善鸡蛋品质。This experiment was designed to investigate the effects of peppermint leaf powder on performance and egg nutritional composition of laying hens during late laying period.Two hundred and sixteen New Yang Black-feathered hens with similar egg production rate of(64.37±5.24)%in laying hens during the late laying period were randomly divided into four groups,hens in the control group fed a basal diet and the other three groups fed the basal diet supplemented with 0.1%,0.2%and 0.4%peppermint leaf powder,respectively,with nine replicates in each group and six hens in each replicate.The whole test period was 35 days,including pilot trial for 7 days and formal trial for 28 days.The results showed as follows:1)compared with the control group,supplementation of dietary peppermint leaf powder did not significantly increase the average daily feed intake(ADFI),feed/egg ratio,laying rate and average egg weight(P>0.05);meanwhile,contents of im-munoglobulin G(IgG)and total protein(TP)in serum was significantly increased in the three treatment groups(P<0.05);dietary supplementation with 0.1%peppermint leaf powder significantly increased the number of large white follicles in the ovaries(P<0.05).2)Compared with the control group,dietary supplementation of peppermint leaf powder significantly enhanced egg shell strength and improved egg shape index(P<0.05);there was also a tendency to increase in the contents of L-phenylalanine,L-tryptophan,L-isoleucine and total essential amino acids in egg white(0.05<P<0.10);0.1%and 0.4%peppermint leaf powder had no signifi-cant effect on fatty acid contents in egg yolk(P>0.05).In conclusion,dietary 0.1%and 0.4%peppermint leaf powder can increase IgG and TP contents in serum of laying hens without affecting performance,which has the potential to enhance immunity of laying hens and improve egg quality.
