| Dairy cows are very efficient in converting fibrous forages into nutritious foods for humans. However, when fed potentially human-edible feeds, such as grains and pulses, dairy cows show very low efficiency in terms of net food production. In this debate, by-products are often mentioned as high quality feeds with reduced human-edible fractions for dairy cows. The aim of this feeding trial was therefore to evaluate the effect of a full substitution of a common concentrate mixture (COM) with a mixture including solely industrial by-products (BP) on milk production, feed intake, and the edible feed conversion ratio (eFCR) in organic dairy production. Cows receiving the BP mixture showed higher intakes of fibre fractions and ether extract, while starch intake... |

| The project objectives are: - to develop and demonstrate a robust system to produce a new organic feed supplement consisting of live insect larvae with an ideal amino acid composition. The project provides a sustainable way to meet the requirement from EU for organic farms (100% organic feed by 2012) and improved animal welfare in poultry flocks. - to investigate the effect of larvae growth on the microbiology of the manure, including selected pathogens and human zoonotic bacteria to assess the microbiological safety to the system, - to investigate a prebiotic effect in the digestive system of poultry, - to demonstrate that the integrated ON-farm system is ideal for treating animal manure through composting with larvae and thereby recycle... |
