“…A higher concentration of nutritive value-determining components such as amino acids, minerals, vitamins and vitamin precursors, enzymes, pro-and prebiotics, essential oils and other substances is also mentioned as an objective of plant breeding [113]. Of course, the plant breeding goals depend also from the climate conditions of region or continent, the animals kept in the region and the level of productivity of animals.…”

“…Many biofortified plants are still in the pipeline and must be tested in animal feeding studies in the next years. More in vitro studies and animal experiments are necessary to assess the bioavailability of micronutrients in biofortified plants and to demonstrate the effects of further desirable ingredients such as enzymes [113]. Furthermore, there is a need for better communication between plant breeders and human and animal nutritionists about the potentials of plant breeding for future improvements in nutrition and health.…”

“…A large number of newly bred plants (crops and vegetables) of the so-called "second generation" (plants with output traits or with substantial changes in composition) with specific benefits for the consumer and animals are being developed or are in development [113]. These plants with increased nutritional content are also called biofortified plants or crops [114][115][116][117].…”

Abstract:The question of how to feed the growing world population is very old, but because of the increase of population and possible climate change, currently it has an explosive impact. Plant breeding can be considered as the starting point for the whole human food chain. Therefore, high, stable and highly digestible yields of phytogenic biomass with low external inputs of non-renewable resources, such as water, fuel, arable land, fertilizers, etc.; low emissions of gases with greenhouse potential during cultivation; and high resistance against biotic and abiotic stressors, including adaptation to potential climate change, and a low concentration of undesirable substances in the plants are real challenges for plant breeders in the future. Virtually unlimited resources such as sunlight, nitrogen and carbon dioxide from the air as well as the genetic pool of microbes, plants and animals can be used to breed/develop optimal plants/crops. Biofortification of plants may also be an objective of plants breeders, but it is more important for human nutrition to avoid micronutrient deficiencies. A lower concentration of undesirable substances in the plants can be considered as more important than higher concentrations of micronutrients in plants/feeds. Animal nutritionists have various possibilities for feed additive supplementation to meet animal nutrient requirements. Examples to reduce undesirable substances in feed plants are discussed and shown in the paper. In summary, plant breeding has a large and strategic potential for global feed and food security. All breeding technologies may contribute to solving important global challenges, such as sustainable use of limited global resources, improved use of unlimited resources, adaption to climate change and lowering global greenhouse gas emission. More publically supported research seems to be necessary OPEN ACCESSAgriculture 2015, 5 1253 in this field. All methods of plant breeding that contribute to a more resource-efficient production of high and stable yields of available biomass should be used/combined.

“…Such biofortified crops contain higher amounts of desirable nutrients/substances such as proteins/amino acids, specific fatty acids, minerals, vitamins, enzymes, antioxidative substances, etc., or lower contents of undesirable substances, such as fibre/lignin, phytates, glucosinolates, mycotoxins, etc., [147] give a review about new events of GM crops in the pipeline as feed for animal nutrition. Adequate feeding studies for the nutritional assessment of such feed of the second generation of GM crops are required.…”
