摘要

Meta分析是能够定量综合同一研究方向中不同独立研究的统计学方法,目前已形成了一套严谨的操作流程,并广泛应用于人类医学、生态学和社会学等领域。但是在以生产性能评估为核心的传统动物营养领域,由于数据资料不完善等因素的制约,Meta分析尚未得到推广和应用。本文简要介绍了Meta分析的发展历史和操作的基本流程,并以已发表的动物生产性能Meta分析为案例,介绍组内标准差的获取与估算方法和各流程对应的具体操作方法,旨在为传统动物营养领域的试验设计与饲料价值评定等提供一种新的研究思路和方法。

Abstract

Meta-analysis is a statistical methodology that can quantitatively review the independent studies under the same theme. So far a set of rigorous operating process has been constructed and is widely applied in human medicine, ecology and sociology. In the classical animal nutrition field which is centered on growth performance evaluation, however, Meta-analysis is not yet extensively promoted due to factors like incomplete data information. This study briefly introduced the history and characteristics of Meta-analysis, and the operating process. Using recently published performance Meta-analyses, the study showcased the acquisition and estimation of within-group standard deviation and each operating step. This study is targeted on offering a brand-new research method for animal nutrition research and evaluation of feedstuff.
