| BACKGROUND: Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day−1 per hen of three coloured carrot varieties (orange, yellow and purple) as forage material in comparison with a standard feed control on egg production, egg yolk colour and deposition of carotenoids in the yolk. RESULTS: Carrot supplementation reduced feed intakes significantly, but not on a dry matter basis. Orange carrot treatment significantly reduced egg mass production, whereas yellow and purple carrot treatments did not differ from the control. Egg and yolk weights of all carrot-supplemented treatmentswere significantly lower than those of the... |

| The aim of the study was to evaluate mussel meal and starfish meals as protein sources for organic layers by studying the effect on production performance, nutrient digestibility and egg quality. A total of 300 Hisex white laying hens (20-week old) were distributed randomly to 6 dietary treatment groups, each with five replicates, including a control diet providing fish meal, 3 diets providing mussel meal (4, 8 and 12 g/100 g) and 2 diets providing starfish meal (4 and 8 g/100 g). Laying rate, egg mass, feed conversion ratio, mortality and live weight of the hens did not differ among treatments. The egg weight was not different from the egg weights of control diets, but the inclusion of 4 g mussel meal resulted in a lower (P < 0.05) egg weight than 8 g... |

| The transition to 100% organic feed ingredients for organic livestock is expected to take effect from January 1st 2020 in Europe. In order to contribute to the goal of 100% use of organic and regional feed for monogastrics, this knowledge synthesis “Feeding monogastrics 100% organic and regionally produced feed“ aims to describe: • the protein need for organic monogastric animals (pigs, layers and broilers), including different breeds and rearing conditions • different protein feed resources, mostly new or not commonly used protein sources, their nutrient content, production prerequisites, and their potential feeding value • small-scale, on-farm equipment for feed processing • different feeding strategies. The knowledge synthesis should enable... |

| Danske økologiske slagtekyllinger har stadig en lav markedsandel - mindre end én procent - selv om produktionen har udviklet sig positivt siden 2014. Skal afsætningen blive bedre i fremtiden, er der brug for både forbedringer i den eksisterende produktion og for helt nye, alsidige og bæredygtige produktionsystemer. I forskningsprojektet Multichick arbejder vi derfor på at udvikle nye funkionelle produktionssystemer, hvor kyllingeproduktion bliver kombineret med produktion af træ og energiafgrøder. Dermed kan man både reducere udvaskning af kvælstof fra kyllingernes udearealer, udnytte arealet bedre og sikre bedre dyrevelfærd. Vi vil identificere både barrierer og muligheder i hele kæden fra jord til bord og komme med forslag til, hvordan den økologiske... |

| Organic eggs make out >15% of the Danish shell egg market. Consumers buy organic eggs based on environmental and animal welfare arguments. However, there is a need for high product quality and diversity of organic eggs to increase the market share further. The overall objective was to investigate different strategies for production of organic eggs of high and differentiable quality regarding appearance (yolk colour and carotenoid composition), sensory quality, shell strength and egg albumen protein content providing more diversified eggs compared with conventional eggs. Specific objectives were to study the effect of hen genotype (layer-type versus “dual purpose”- type), identify new protein feed sources for organic laying hens in order to improve the... |

| The supply of protein and essential amino acids will undoubtedly be a great challenge for European poultry nutritionists when the transition to 100% organic feed ingredients for organic poultry production becomes reality. To avoid costly and energy consuming oversea transports connected to the import of soya beans, much research effort has focussed on the exploitation of alternative locally grown protein sources to increase the sustainability of organic production systems. Besides the cultivation of protein crops like legumes (peas, lupin, and faba been) and seeds (sunflower, rapeseed), new approaches including the feeding of protein concentrates from green biomass obtained by bio-refinement are discussed. At present, many of the alternative protein... |
