In this meta-analytical study, in vivo experimental studies with adsorbents and biological products as feed additives for inactivation of aflatoxin (AF) in poultry feeds are summarized. Totally, 231 researches carried out in 42 different countries were examined and listed with the first author’s country name and presented their results in summary. This review presents the results of the experiments for nutritionists in the feed industry and scientists and provides a basis for total evaluation on the basis of regional results. The studies have been performed mostly in broilers (85%) among poultry species; and mostly in humid countries and/or the countries which import feedstuffs from them. Experiments to reduce negative effects of AF in poultry feed have been mainly performed with clays such as bentonites (BENT) and hydrated Na Ca aluminosilicate (HSCAS) single or in combination with biological matters such as yeast (Saccharomyces cerevisiae; SCE) and yeast derivates (Esterified glucomannan; EGM). The best way for producers and researchers, it is preferable to evaluate the preventive efficacy of feed additives as total in terms of performance, biochemical-hematological, immunological and gross and histo-pathological parameters, comparing AF group with AF plus feed additive groups. Scientists can assess the preventive efficacy and practical usability of feed additives in more detail by following the titles of articles, associate authors and/or materials and methods of related articles. In fact, for application in practice, focus on limiting AF contamination by optimizing harvesting and storage conditions should be stressed instead of expecting miracles from feed additives which have shown positive effects under experimental conditions.
