益生菌已成为提高抗病能力和刺激养殖虾生长的有前途的替代品。目前工作的目的是通过荟萃分析评估益生菌添加对虾存活和生长性能的影响。 PubMed、SciELO 和 Google Scholar 搜索引擎搜索了 1980 年至 2017 年发表的相关研究，不排除语言。我们仅从使用没有明显疾病的对虾的文章中选择实验，其结果发表在同行评审的期刊上，并采用任何分散措施。选择存活率、特定生长率（SGR）和饲料转化率（FCR）作为结果。我们评估了实验设计、对虾种类、幼体或幼体后期、益生菌菌株、给药方式等。总共包括 100、60 和 49 项实验，分别评估益生菌对生存、SGR 和 FCR 的影响。考虑到来源，与对照组相比，益生菌提高了存活率（SMD=3.068，95% CI 2.594至3.543），并改善了汇总标准化均值差异随机效应模型中的SGR（SMD=3.811，95% CI 3.269至4.354）和FCR（SMD=−3.194，95% CI -3.469至−2.920）异质性和发表偏差（即发表与否的决定取决于实验的结果，例如保留负面结果）。经过益生菌处理的虾的存活率、SGR 和 FCR 均得到改善。据我们所知，这是第一份旨在研究益生菌对虾存活和生长性能影响的荟萃分析报告。
Probiotics have emerged as promising alternatives for improving resistance to diseases and stimulating growth of farmed shrimp. The aim of the present work was to assess the effect of probiotic addition on shrimp survival and growth performance through meta-analysis. PubMed, SciELO and Google Scholar search engines were searched for relevant studies published from 1980 to 2017 without language exclusion. We only selected the experiments from articles using penaeid shrimps without apparent disease, with the results published in peer-reviewed journals with any dispersion measure. Survival, specific growth rate (SGR) and feed conversion ratio (FCR) were selected as outcomes. We evaluated experimental design, penaeid shrimp species, larval or postlarval stage, probiotic strain, modes of administration among others. A total of 100, 60 and 49 experiments were included to assess probiotic effects on survival, SGR and FCR, respectively. Probiotics increased survival compared to controls (SMD = 3.068, 95% CI 2.594 to 3.543) and improved SGR (SMD = 3.811, 95% CI 3.269 to 4.354) and FCR (SMD = −3.194, 95% CI -3.469 to −2.920) in the pooled standardized mean difference random effect model, considering the source of heterogeneity and publication biases (i.e. where the decision to publish or not depends on the outcome of the experiment, e.g. withhold negative outcomes). Survival, SGR and FCR were improved in shrimps treated with probiotic. To our knowledge, this is the first report of a meta-analysis designed to investigate the effects of probiotics on shrimp survival and growth performance.
