Some parameters of productivity and metabolism in calves at use in rations of canned corn gluten

Dry corn gluten contains about 60% crude protein, but at the moment is quite expensive because of the high consumption of energy when it is received. In the manufacturing process passes step podsguscheniya gluten content to 38-40% solids in this phase and its value is sufficiently low as compared with the dry form of the commodity. This makes podsguschenny gluten promising high-protein feed additives, the use of which allows to increase the productivity of young cattle at growing. However, the pH = 5.6-5.8, that in the summer temperatures can not store this product for more than 24 hours. This fresh podsguscheny gluten has a distinct smell of hydrogen sulfide, which is associated with the use of sulfurous acid in its production. Gluten organoleptic characteristics such animals consume reluctantly. At the same time, preserving its acid to pH = 3.8-4.0 odor disappears almost immediately and increased shelf life up to six months. When using canned corn gluten podsguschenogo (CCCC) in rations of young cattle marked its good palatability and positive impact on productivity.
