| In the present study a set of 108 spring barley (H. vulgare L.) accessions were cultivated under predicted future levels of temperature and [CO2] as single factors and in combination (IPCC, AR5, RCP8.5). Across all genotypes, elevated [CO2] (700 ppm day/night) slightly decreased protein concentration by 5%, while elevated temperature (+5 °C day/night) substantially increased protein concentration by 29%. The combined treatment increased protein concentration across accessions by 8%. This was an increase less than predicted from strictly additive effects of the individual treatments. Despite the increase in grain protein concentration, the decrease in grain yield at combined elevated temperature and elevated [CO2] resulted in 23% less harvestable protein.... |

| Wheat and triticale are a primary energy source in the feedstuffs in swine diets. Enzyme digestibility of organic matter (EDOM) is an index used in the feed evaluation system for pigs. This is based on the close linear relationship between the in vitro enzyme digestibility of organic matter (EDOM) and in vivo total tract digestibility of energy (Boisen & Fernández, 1997). EDOM is a complex parameter calculated from the protein, carbohydrate, starch and fibre fractions undergoing a three step enzymatic incubation. It is therefore a challenge to relate EDOM to specific chemical bonds. |

| In conventional seed production of grasses and clover it is recognised that a low plant density in the seed crop stimulates the reproductive development and hence increase seed yield. Most temperate forage species of grasses and white clover establish slowly and have a relatively poor ground cover, which limits the competition against weeds. In order to optimise quality and yield in organic grass and clover seed production alternative establishment methods have been identified. These methods enhance crop competitiveness against weeds and allow for mechanical weed control. Establishing the under sown seed crop right between the cereal cover crop row provides a higher ground cover, and the establishment rate of the seed crop is enhanced. This method of... |

| Feed value in form of FEsv (Feed unit / kg dry matter, for piglets) and FEso (Feed unit / kg dry matter, for sows), EDOM (Enzyme Degradable Organic Matter) and EDOMi (Enzyme Degradable Organic Matter, Ileum) is used in the feed evaluation system for pigs. Analysis of feed value have highlighted that there is a significant variation between varieties as well as due to an environmental variation between regions and the harvest year. The chemical analysis is, however, time-consuming and costly, and it is therefore desirable to have a rapid and less expensive method, which makes it possible to carry out more analyses in-situ. Near infra-red reflection spectroscopy (NIRS) is appropriate as a standard analysis of dry matter, total N and starch in grains,... |
