| The main objective of this thesis was to elucidate the effects of regrowth grass silage and red clover silage on nutrient supply and milk production of dairy cows as compared with primary growth grass silages. In the first experiment (publication I), two primary growth and four regrowth grass silages were harvested at two stages of growth. These six silages were fed to 24 lactating dairy cows with two levels of concentrate allowance. Silage intake and energy corrected milk yield (ECM) responses, and the range in these response variables between the diets, were smaller when regrowth silages rather than primary growth silages were fed. Milk production of dairy cows reflected the intake of metabolizable energy (ME), and no differences in the ME utilization... |

| Silvopastoral systems that combine livestock and trees offer two main advantages for the animals. First, trees modify microclimatic conditions which can have beneficial effects on pasture growth and animal welfare. Second, trees also provide alternative feed resources during periods of low forage availability. This paper reports on research carried out within the Sustainable Organic and Low Input Dairying (SOLID) project to investigate the multifunctional potential of a novel integrated willow-based bio-energy/organic dairy production system in the UK, especially the role of tree fodder for feed supplementation in organic dairy systems. The nutritional value of two ages (1st and 2nd year re-growth) of short rotation coppiced willow was assessed in two... |

| This literature review evaluates the potential of a range of by-products from the agricultural,greenhouse, forestry, food processing and bioenergy sectors and agro-forestry systems as feed components in organic and low input dairy systems. The variability of the raw materials further modified by differing processing methods results in wide range of feed materials available. Innovative use of novel and underutilized feed resources has the potential to improve the efficiency of the “green economy”. |

| The objective of the current work was to assess various novel and underutilized feeds and thus increase the awareness of various novel feeding solutions to support organic and low-input dairy production. A set of various feeds representing high protein feeds, by-products from distilling, wineries, fruit and vegetable production, whole crop cereals, agroforestry and wood derived materials were collected from Spain, Romania, UK and Finland and analysed for chemical composition and digestibility. The results can be used to aid in exploiting the potential of different feed resources and in ration formulation, and to demonstrate potential to widen the basis of feed supply on organic and low-input dairy farms. The use of various by-products as animal feeds... |
