基　　金：蛋鸡养殖场玉米豆粕减量替代技术研究与示范(H20230331)。

摘　　要：我国大豆年产量较低,无法满足生产生活需求,严重依赖进口,国际上大豆价格不断飞涨,而小麦替代玉米可以实现豆粕减量。ε-聚赖氨酸盐酸盐(ε-poly-L-lysine hydrochloride,ε-PLH)是一种天然防腐剂和抗菌剂,常用于食品等领域。本研究旨在探讨小麦豆粕饲料添加ε-PLH对蛋鸡(Gallus gallus domesticus)生产性能、蛋品质和肝脏脂质代谢的影响。实验选取21周龄海兰褐蛋鸡共120只,随机分为4组,每组5个重复,每个重复6只鸡,分为对照组、小麦组、小麦+0.01%ε-PLH组和小麦+0.05%ε-PLH组,进行3周的换粮饲养,正式实验期为12周。结果表明,对照组和3个处理组产蛋率和料蛋比均无显著差异,小麦+0.01%ε-PLH组和小麦+0.05%ε-PLH组的平均蛋重显著高于对照组(P<0.05);小麦组、小麦+0.01%ε-PLH组和小麦+0.05%ε-PLH组蛋形指数、蛋白高度和哈氏单位显著高于对照组(P<0.05),小麦+0.01%ε-PLH组蛋壳厚度显著高于对照组和小麦组(P<0.05);小麦+0.01%ε-PLH组能够显著上调过氧化物酶体增殖物激活受体γ(peroxisome proliferator-activated receptor gamma,PPARG)、脂肪酸去饱和酶2(fatty acid desaturase 2,FADS2)和脂肪酸结合蛋白1(fatty acid binding protein 1,FABP1)等脂质代谢相关基因的表达量(P<0.05)。由此可见,小麦替代玉米并添加ε-PLH可以改善蛋鸡的生产性能、蛋品质和缓解肝脏脂质沉积。本研究为将ε-PLH应用于畜禽养殖提供理论和实践支持,也为国家玉米豆粕减量替代政策提供备选方案。China's annual soybean production is insufficient to meet the demands of production and daily life,resulting in a heavy reliance on imports.Internationally,the price of soybeans continues to soar.However,substituting wheat for corn can lead to a reduction in soybean meal usage.ε-Poly-L-lysine hydrochloride(ε-PLH)is a natural preservative and antimicrobial agent commonly employed in the food industry and other related fields.This study aimed to investigate the effects of addingε-PLH to wheat-soybean meal feed on the production performance,egg quality,and hepatic lipid metabolism of laying hens(Gallus gallus domesticus).The experiment involved a total of 120 Hy-line brown laying hens at 21 weeks of age,which were randomly divided into 4 groups.Each group comprised 5 replicates,with 6 chickens per replicate.The groups were designated as follows:Control group,wheat meal group,wheat meal+0.01%ε-PLH group,and wheat meal+0.05%ε-PLH group.The hens were fed with the respective diets for 3 weeks during the adaptation period,followed by a formal experimental period of 12 weeks.The results indicated that there were no significant differences in laying rate and feed to egg ratio among the control group and the three treatment groups.However,the average egg weight of the wheat meal+0.01%ε-PLH group and the wheat meal+0.05%ε-PLH group was significantly higher than that of the control group(P<0.05).The egg shape index,albumen height,and haugh unit of the wheat meal group,wheat meal+0.01%ε-PLH group,and wheat meal+0.05%ε-PLH group were significantly higher than those of the control group(P<0.05).Additionally,the eggshell thickness of the wheat meal+0.01%ε-PLH group was significantly higher than that of the control group and the wheat meal group(P<0.05).Wheat meal+0.01%ε-PLH group could significantly up-regulate the expression of lipid metabolism related genes such as peroxisome proliferator-activated receptor gamma(PPARG),fatty acid desaturase 2(FADS2)and fatty acid binding protein 1(FABP1)(P<0.05).Thus,it could be inf
