“…Previous studies have found that feed‐derived plant DNA fragments can be identified in the digestive tracts, stomachs, blood, heads, kidneys, livers and muscles of animals (Ma et al, 2013; Morera et al, 2016; Sieradzki et al, 2013). These findings are in contrast with other studies, which failed to detect fragments of transgenic or reference genes in a variety of animal tissues and blood (Furgał‐Dierżuk et al, 2015; Lu et al, 2015; Yonemochi et al, 2010). As DNA stability and integrity are negatively influenced by various physical conditions and chemical treatments that occur during feed processing and storage, DNA in feed is subjected to degradation by grinding, extrusion, heating and hydrolysis.…”

The global commercialization of genetically modified (GM) crops has increased the likelihood of feed‐derived transgenic DNA uptake and raised concerns regarding the fate of such DNA fragments in animals consuming a GM diet. The present study applied a novel droplet digital polymerase chain reaction (ddPCR) method to quantitatively detect the concentrations of feed‐derived transgenic (Cry1Ie) and endogenous (rubisco) plant DNA in the livers, intestinal tracts and muscles of zebrafish (Danio rerio) fed GM maize for uantifying feed‐derived DNA in animal tissues as a more sensitive and reliable alternative to qPCR.

“…Furgal Dierżuk et al (2015) conducted same study on 40 Polish Holstein-Friesian cows to evaluate the effects of GM maize (MON 810) and soybean meal (Roundup Ready, MON 40-3-2) on performance parameters, milk composition, blood serum metabolite profiles and transfer of tDNA into the milk of cows. This study was conducted from the 3 rd week before parturition to the 305th day of lactation.…”

Genetically modified (GM) crops are being planted at large scale worldwide. In most of the countries, GM crops are processed into livestock feed. The land is used for cultivation of GM plants has been increased in recent years; in 2012 GM plants were grown on over 170 million hectares in 28 countries by 17.3 million farmers and extended to 185.1 million hectors in 2016 worldwide. GM plants have been used as feed for animals and the number of studies has proved their safety for animal and public health. This paper reviews the possible effects of GM crops on livestock, poultry, and aquatic animals by reviewing different type of studies, in which parameters such as performance, reproductive and health assessment were investigated. The most of peer-reviewed papers evaluating the effects of feeding animals with transgenic crops were based on GM plants with improved agronomic traits i.e. herbicide-tolerant plants and pets-tolerant plants; however, in some cases GM plants with boosted nutritional properties assessed. In most experiments, either Bt (Bacillus thuringiensis) maize, Roundup Ready (RR) soybean or both fed to animals. Measurable differences in various parameters were mostly observed in Bt maize and soybean fed separately or simultaneously to animals. In this review, scientific studies showing the effects of the use of GM products in the nutrition of domestic animals on performance, health and reproductive parameters are investigated.
