Sugarbeet pulp is the fibrous, energy rich by-product resulting from the water extraction of sugar contained in the root of the sugarbeet (Beta vulgaris L.). Sugarbeet pulp is relished by all classes of farm animals (ruminants, pigs, poultry, rabbits and also horses) and much valued by farmers. It has outstanding feeding value gathering qualities of both chopped hay (for fibre) and maize (for energy content) . However, it should be noted that sugarbeet pulp results from various processes and may have variable quality.
In the world, 86% of sugarbeet roots are processed into sugar and yield sugar beet pulp . It has been reported that 1 ton of sugar beets yields approximately 150 kg of sugar and 50 kg of dehydrated sugar beet pulp.
Dehydrated sugar beet pulp is often found in the form of pellets that have been granulated, sometimes by using molasses as binding agent. Dehydrated sugar beet pulp that contains molasses is called molassed sugar beet pulp or molassed beet pulp pellets . If dehydrated sugar beet pulp does not contain molasses they can be referred to as molasses-free sugar beet pulp . In France, however, dried sugar beet pulp is mostly molasses-free.
During sugar production the beets are first cleaned and shredded into cossettes, from which the juice is extracted by using hot water (60-70°C). The juice is then processed such as that of sugar cane, yielding sugar and beet molasses. After juice extraction the sugarbeet extracted fibrous material, that mostly consists of sugarbeet cell wall and about 2-4% sugar, is the sugar beet pulp. It can be used in many ways. In order to produce dehydrated sugar beet pulp, the pulp is first pressed to extract residual sugar and water and then dehydrated in a drum dryer (down to 11% moisture) and pelletized (with possible addition of molasses as binding agent) for better preservation. The final product is dehydrated sugarbeet pulp, a much relished feed for most livestock animals that has long shelf-life and is easy to transport and to store. Dehydrated sugar beet pulp complies with year-round feeding programmes.
