Prospects for the use of genetically modified crops with improved nutritional properties as feed materials in poultry nutrition

Abstract

Genetically modified (GM) plants constitute an increasingly significant part of the crops available on the feed market. To date, the most common GM plants have been those with enhanced agronomic traits. Known as 'first-generation transgenic plants', they are substantially equivalent to materials from conventional, parental plant lines. Recently, intensive experimental work using genetic engineering methods, have resulted in the production of transgenic plants with substantial changes in chemical composition, these are referred to as second-generation GM plants. The main objective of such transgenesis is to improve the nutritional properties of crops by increasing the level of desirable substances or decreasing the quantity of harmful compounds in the seeds. This review discusses the use of GM crops with enhanced nutritional properties as feed materials for poultry. On the basis of the information presented, it can be concluded that GM crops with improved nutritional value, enhanced available phosphorus content, an increased concentration of limiting amino acids, or containing genes expressing transgenic enzymes or antimicrobial substances could offer poultry producers considerable benefits.

Carotenoid‐enriched transgenic corn delivers bioavailable carotenoids to poultry and protects them against coccidiosis

“…Carotenoids act as antioxidants but some are also vitamins with essential biological functions (Bai et al ., ; Farré et al ., ; Liu et al ., ; Lucas et al ., ; Surai, ; Swiatkiewicz and Arczewska‐Włosek, ). For example, β‐carotene and other pro‐vitamin A carotenoids are converted into retinol, an essential component of the visual pigment rhodopsin that also helps to maintain epithelial and immune cells, and into retinoic acid, a coregulator of developmental gene expression (Harrison, ; Jlali et al ., ).…”

Effect of Genetically Modified Organisms Feed Ingredients (Corn And Soybean) in Diet on Egg Production, Egg Broken Rate and Egg Quality in Layers

“…normal soybeans (Swiatkiewicz & Arczewskawłosek, 2011). Soybeans that have been genetically modified to produce traits that increase the nutritional value for poultry, like reduced trypsin inhibitor soybeans and low-lectin soybeans, low-oligosaccharide SBM, and high-protein soybean meal (SBM) (Stein et al, 2008).…”

Does the Inclusion of Second Generation Genetically Modified Plants in Feeds have any effect on Animal Performance?

“…myo-inositol 1, 2, 3, 4, 5, 6hexakisphosphate (Yang, et al, 2017c). The P that is bound in phytates is not efficiently utilized in the gastrointestinal tract of monogastric animals due to its poor solubility (Swiatkiewicz & Arczewska-Włosek, 2011). In order to improve P availability in crops, genetic engineering methods leading to the expression of transgenic phytase (phy gene), the enzyme that hydrolyzes phytate bonds, in seeds are used (Gao et al, 2014).…”
