摘　　要：本试验通过Meta分析研究蛋鸡饲粮中补充有机硒或无机硒对其生产性能及蛋硒含量的影响。我们检索了从2015年1月1日至2021年7月1日在知网、维普、万方、Web of Science、ScienceDirect以及Pub Med等数据库中发表的有机硒或无机硒对蛋鸡生产性能及蛋硒含量影响的相关论文。通过Comprehensive Meta Analysis V3软件对提取的数据进行Meta分析。采用随机效应模型计算标准化均数差(SMD)和95%置信区间(95%CI)的估计值,在确定的1921篇文献中共19篇文献(8249只蛋鸡)符合条件纳入Meta分析。通过绘制漏斗图评估发表偏倚,利用Meta回归分析和调节效应分析解释异质性来源。结果显示:与无机硒相比,在蛋鸡饲粮中补充有机硒可以更有效地提高蛋鸡的产蛋率(SMD=0.477%,P=0.005)、蛋重(SMD=0.697%,P<0.001)、料蛋比(SMD=-1.636%,P<0.001)及蛋硒含量(SMD=5.965%,P<0.001)同时,在蛋鸡品种的选择上,海兰褐蛋鸡较优于罗曼蛋鸡,并且试验周期与添加剂量在模型中呈正相关。综上所述,在饲粮中添加有机硒对蛋鸡生产性能及蛋硒含量的提高效果优于无机硒,该结果可为探究硒在蛋鸡生产中的应用提供有益参考。The aim of this study was to determine the effects of supplementing organic selenium or inorganic selenium in the diet of laying hens on their performance and egg selenium content by Meta-analysis.The publications searching for organic selenium and inorganic selenium for laying hens were collected from the databases of CNKI,CQVIP,Wanfang,Web of Science,Science direct and Pub Med.The retrieval period was from January 1,2015 to July 1,2021.The Meta-analysis was conducted using Comprehensive Meta Analysis V3software.A random-effect model was used to calculate the standardized mean difference(SMD)and 95%confidence interval(95%CI).A total of 19 articles out of the identified 1921 articles(8249 laying hens)were eligible and included in the Meta-analysis.Publication bias was evaluated by funnel plot,and the source of heterogeneity was explained by Meta-regression analysis and regulatory effect analysis.The results showed as follows:compared with inorganic selenium,supplementation of organic selenium in the diet could increase the laying rate(SMD=0.477%,P=0.005),egg weight(SMD=0.697%,P<0.001),feed to egg ratio(SMD=-1.636%,P<0.001)and egg selenium content(SMD=5.965%,P<0.001)more effectively.At the same time,in the selection of laying hens,Hy-Line brown laying hens were better than Roman laying hens,and the test period was positively correlated with the adding dose in the model.In conclusion,adding organic selenium to the diet is better than inorganic selenium,which provides a useful reference for exploring the application of selenium in laying hen production in the future.
