In most cases, the animals and poultry’s feeding ration consists of compound feed, therefore to saturate these feed with natural vitamins, it is recommend by zootechnicians sprouted grain to add. Dry type of feeding on livestock and poultry complexes is used. At the same time, sprouted grain better than dry one is consumed. It has a pleasant sweet taste, and at group keeping, because of stronger individuals do not eat the given entire mass of sprouted grain out, it must be mixed with compound feeds before it will be given out. Sprouted grain has a high humidity - 54-56%; therefore, in order to preserve its properties for a long time, the sprouted grain must be dried, cooled or preserved chemically. A mixture of wet sprouted grain with combined feed it should be given to animals within 1,5-2 hours. To take attention at the sprouted grain’s storage short duration of, its using at products producing is problematic. Therefore, there is a need own grain’s germination capacities on livestock and poultry complexes to create. The installation for grain’s germination is given. It is characterized by design’s simplicity and allows the water for grain’s soaking to cleaned, disinfect and use repeatedly. The device and operation’s principle of the presented experimental grain germination’s installation are described. The factors influencing the grain’s germination and optimization’s criteria by which quantitative and energy indicators of this installation’s operation can be determined are given.
