Pigs: Use of biofuel co-products, economics and nutritional limitations
Published online by Cambridge University Press: 23 November 2017
Extract
It is anticipated that there will be a significant increase in the quantity of co-products available from the biofuel industry for use in animal feed. The co-products are the result of either biodiesel or bioethanol production. Biodiesel is produced from oil. One of the main sources of oil is oil seed rape but other oil seeds such as sunflower, Crambe and Camelina sativa (Cottrill et al., 2007) may be used. Bioethanol is produced from the fermentation of sugar which is either added directly to the process or obtained from the digestion of starch. The co-products produced include glycerol (glycerine or glycerin) from the production of biodiesel and dried distillers grains with solubles (DDGS) from the production of bioethanol from starch.
