Granulated dry spent grain is a spent grain dried and compressed into pellets. It has a moisture content of up to 10%, and a bulk density of at least 700 kg/m3. For these reasons, it can be stored for a long time, transported over considerable distances and in larger volumes than a non-granulated spent grain.
Granulated dry spent grain has a high protein content (24-26%), contains a rather large share of digestible protein (about 17%), and important microelements (phosphorus, calcium, magnesium, copper, iron), fatty acids and E and F vitamins. Because of this, spent grain is a high-quality protein feed for many types of farm animals and poultry, rabbits, fur-bearing animals and dogs. Practical experiments have established that the addition of granulated dry spent grain significantly increases the weight of fattened animals and reduces the cost of weight gain. At the same time, the use of recommended doses does not lead to any negative side effects.
