    The processing of fish leads to a significant removal of parts of the fish, such as heads, bones, guts, etc., these parts can represent between 30-70% of the fish. The fish silage process transforms fish waste into a liquid mix of hydrolysed proteins, lipids, minerals and other nutrients, easily digestible by both terrestrial and aquatic animals. It can also serve as an excellent fertilizer. Fish silage could make a difference in terms of; i) environmental impact - by reducing levels of waste, ii) animal health - by providing nutrients and bioactive components, iii) economic gains - as waste is converted into a valuable product that can replace expensive feed ingredients, or be used as a fertilizer. This manual will provide technical guidance and explain each step and main principles of production and utilization of fish silage.

    Utilization of fruit and vegetable wastes as livestock feed and as substrates for generation of other value-added products 2013

    By 2050 the world will need to feed an additional 2 billion people and will require 70 per cent more meat and milk. The increasing future demand for livestock products, driven by increases in income, population and urbanization will impose a huge demand on feed resources. Sustainability of feed production systems is being challenged due to biophysical factors such as land, soil and water scarcity, food-fuel-feed competition, on-going global warming and frequent and drastic climatic vagaries, alo ng with increased competition for arable land and non-renewable resources such as fossil carbon-sources, water and phosphorus. A key to sustainable livestock development is efficient use of available feed resources including reduction in wastage, and enlargement of the feed resource base through a quest for novel feed resources, particularly those not competing with human food.
