| With the reform of the Common Agricultural Policy of the EU (CAP) there is a renewed attention for implementation of agroforestry and silvopastoral systems. The multifunctional use of trees for energy production, nutrient cycling, carbon storage, biodiversity, landscape and -last but not least- fodder could make trees a third crop next to grass and maize on dairy farms. To decide which trees to use for planting, it is important to have also insight into the feeding value of the different tree leave species. Therefore a database has been created on the basis of available literature on feeding values of leaves and twigs. Compared to grass, the in-vitro Organic Matter Digestibility of tree leaves is relatively low. However, crude protein and mineral levels of... |

| The potential of free range areas and grassland on organic farms for performing natural behaviour and offering natural feed is not fully utilized yet. Moreover, there are also chances to be picked up for enhancing biodiversity, carbon fixation and mineral cycling. For example, Dutch organic and free range poultry farms together have 2300 ha range area available. In dairy farms this area is much larger. Challenges on goat and cow farms are a natural enrichment of the ration of the animals and making larger areas of the meadows attractive by providing natural shelter against bad weather. We try to ‘solve’ these problems by introducing forestry in animal production and designing silvopastoral systems. Silvopastoral systems, which are the combination of trees... |

| In this study the effect of three colostrum types; goat, cow and artificial colostrum, on serum gamma globulin concentration (GGC), growth and health of goat kids during the first three months of the rearing phase was measured. Thirty newborn goat kids were randomly assigned to three experimental groups; goat colostrum (GC), cow colostrum (CC) and artificial colostrum (AC). At 2, 28, 56 and 86 days serum GGC and live weight were measured. The three colostrum types were analysed on immunoglobulin G (IgG). Goat colostrum contained twice as much IgG as cow colostrum and artificial colostrum. At 2 and 28 days GC kids had a higher serum GGC than CC and AC kids. At 56 and 86 days no significant differences in serum GGC between the groups were found. No effect of... |

| In the search for sustainable grassland systems, self-regulating processes in the soil become increasingly important. Soil biota play an important role in these processes and in the provision of various ecosystem services. For grassland systems important ecosystem services are supply of nutrients, soil structure maintenance and water retention. For developing and optimising sustainable grassland systems, insight is needed into the mechanisms by which soil biota are influenced by management and what it means for the functioning of the soil-plant system. Interactions between soil and plants can be represented by a cyclic conceptual framework including plant/roots, soil biota and soil properties. The challenge for sustainable grassland is to allow this cycle... |
