“…The enzyme can be found in concentrations as high as 0.05% of the fresh tuber weight, with a specific activity of 3013 U/mg β-glucanase. The objective of a study conducted on broiler chickens was to evaluate this GM potato as a source of β-glucanase in barley-based chicken diets (Baah et al, 2002). Including this at 0.6 kg/t as a source of β-glucanase in barleybased diets for broiler chickens significantly improved feed conversion by 8.8% and, at 1.2 kg/t, significantly reduced ileal digesta viscosity by 42%.…”

“…However, performance parameters were significantly worse compared to the control group, where the chickens were fed a barley-based diet supplemented with a commercial β-glucanase preparation. The authors concluded that improved level and activity of expression is required in the transformed potato in order for it to have potential as an enzyme additive to barley-based diets (Baah et al, 2002).…”

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.

“…For example, transgenic rice, corn, and canola overexpressing phytase from a bacterial origin supplemented in poultry feed resulted in significant improvements in nutritional value and a remarkable reduction in phosphorus excretion (Chen et al ., 2013 ; Hamada et al ., 2006 ; Hong et al ., 2004 ; Nyannor et al ., 2007 ; Zhang et al ., 2000 ). Broiler chickens fed with β‐glucanase from transgenic potatoes expressing β‐glucanase from Fibrobacter succinogenes had significantly improved feed conversion and reduced ileal digesta viscosity (Baah et al ., 2002 ). The expression of xylanase from Streptomyces olivaceoviridis in transgenic potatoes provides an alternative to present‐day xylanase additives to animal feed (Yang et al ., 2007 ).…”

Summary Currently, feed enzymes are primarily obtained through fermentation of fungi, bacteria, and other microorganisms. Although the manufacturing technology for feed enzymes has evolved rapidly, the activities of these enzymes decline during the granulating process and the cost of application has increased over time. An alternative approach is the use of genetically modified plants containing complex feed enzymes for direct utilization in animal feedstuff. We co‐expressed three commonly used feed enzymes (phytase, β‐glucanase, and xylanase) in barley seeds using the Agrobacterium‐mediated transformation method and generated a new barley germplasm. The results showed that these enzymes were stable and had no effect on the development of the seeds. Supplementation of the basal diet of laying hens with only 8% of enzyme‐containing seeds decreased the quantities of indigestible carbohydrates, improved the availability of phosphorus, and reduced the impact of animal production on the environment to an extent similar to directly adding exogenous enzymes to the feed. Feeding enzyme‐containing seeds to layers significantly increased the strength of the eggshell and the weight of the eggs by 10.0%–11.3% and 5.6%–7.7% respectively. The intestinal microbiota obtained from layers fed with enzyme‐containing seeds was altered compared to controls and was dominated by Alispes and Rikenella. Therefore, the transgenic barley seeds produced in this study can be used as an ideal feedstuff for use in animal feed.
