Abstract

In this meta-analytical study, in vivo experimental studies withadsorbents 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 wereexamined and listed with the first author’s country name andpresented their results in summary. This review presents theresults of the experiments for nutritionists in the feed industryand scientists and provides a basis for total evaluation on the basis of regional results. The studies have been performed mostlyin broilers (85%) among poultry species; and mostly in humidcountries and/or the countries which import feedstuffs fromthem. Experiments to reduce negative effects of AF in poultryfeed have been mainly performed with clays such as bentonites(BENT) and hydrated Na Ca aluminosilicate (HSCAS) single orin combination with biological matters such as yeast (Saccharomyces cerevisiae; SCE) and yeast derivates (Esterified glucomannan; EGM). The best way for producers and researchers, itis preferable to evaluate the preventive efficacy of feed additivesas 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 usabilityof feed additives in more detail by following the titles of articles, associate authors and/or materials and methods of relatedarticles. In fact, for application in practice, focus on limiting AFcontamination by optimizing harvesting and storage conditionsshould be stressed instead of expecting miracles from feed additives which have shown positive effects under experimentalconditions.

Özet

Bu meta-analitik çalışmada, kanatlı yemlerinde aflatoksinlerin etkisinin azaltılmasına yönelik yem katkı maddesi olarak adsorbanlar ve biyolojik ürünlerle gerçekleştirilen in vivo deneysel çalışmalar özetlendi. Toplam 42 farklı ülkede yürütülen 231 araştırma incelenerek ilk yazarın ülke adıyla listelendi ve sonuçları özet halinde sunuldu. Bu derleme, yem sektörü temsilcileri ve bilim insanlarına yapılan çalışmaların sonuçlarını sunmakta ve bölgesel sonuçlara dayalı olarak bütüncül değerlendirme için bir temel oluşturmaktadır. Araştırmalar çoğunlukla kanatlı türlerinden broyler civcivlerde (%85) ve nemli iklime sahip ülkeler ile o ülkelerden yem hammaddesi ithal edenlerde yoğunlaşmaktadır. Kanatlı yemlerinde aflatoksinlerin etkilerini azaltmak için çoğunlukla bentonitler (BENT) ve hidrate Na Ca aluminosilicat (HSCAS) gibi killer ile bunların maya (Saccharomyces cerevisiae; SCE) ve maya komponentleri (Esterified glucomannan; EGM) gibi biyolojik ürünler ile kombinasyonlarıyla gerçekleştirilmiştir. Üreticiler ve araştırıcılar için yeme aflatoksin bağlayıcı olarak katılan yem katkısının etkinliğini belirlemede en iyi yol, aflatoksin ve aflatoksin + bağlayıcı madde grubunu karşılaştırılarak elde edilen sonuçların performans, biyokimyasal-hematolojik, immunolojik ve makroskobik-histopatolojik verilerin hepsinin “bir bütün olarak” ele alınması ve değerlendirilmesidir. Üreticiler ve araştırıcılar denemelerin bütününe ulaşıp koruyucu maddenin pratikte kullanılabilirliğini değerlendirmek için makale başlıklarını, ortak yazarları ve/veya makalenin materyal ve metodunu takip edebilirler. Pratikteki uygulamalar için deneysel koşullar altında olumlu etkiler gösteren yem katkılarından mucizeler beklemek yerine aslında hasat ve depolama koşullarını optimize ederek aflatoksin kontaminasyonunun sınırlandırılmasına odaklanmak gerekir.
