| Two experiments were conducted to study the effects of different forage crops on productivity and some egg quality parameters of small flocks of organic laying hens fed whole wheat or concentrates. Each experiment was carried out in a split plot design with two different forage crops and two types of supplementary feed (typical concentrate for organic layers versus whole wheat) with three replications. In the first experiment the tested forage crops were of a well-established grass/clover and a mixture of forbs (Fagopyrum esculentum, Phacelia tanacetifolia and Linum usitatissimum). In the second experiment the tested forage crops were a well-established grass/clover and chicory (Cichorium intybus cv. Grassland Puna). The results on productivity and egg... |

| 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... |

| Two types of milk, skim milk and non-standardized raw milk, were heat treated using direct heating by instant infusion pasteurization with treatment temperatures in the range from 72°C to 120°C and with holding times of less than 1 second. Indirect heating by HTST pasteurization (72°C for 15 seconds) was used for comparison. The inactivation of microorganisms reached at least the same level when using instant infusion pasteurization compared to HTST pasteurization. Changes in the physical-chemical properties were observed in the skim milk fractions of instant infusion pasteurized non-standardized milk, whereas for instant infusion pasteurized skim milk less influence from the treatments was observed. |

| 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... |
