Development of cereals for animal feed technology

The technological process of cereals production used in the production of feed stuff, which includes the following basic steps: grain moistening; binning of moistened grain for redistribution of moisture in the bulk of kernel; steaming of moistened grain; rolling of steamed grain; drying and cooling of flakes - is developed. In the production of flakes from scoured barley and oat grain before feeding to the rolling line film removal from the grain of these crops and the separation of the husks is carried out by one the existing methods: the method of grinding, followed by sifting and eventilation of films from tail fractions or a method of peeling on special machines with a separation of films. Wet-heat treatment of grain, followed by rolling helps to improve taste and palatability of feed, improves the nutritional value of carbohydrate and protein complexes, reduces the exertion of the body to digest food nutrients, allows to inactivate antinutritional substances and free the grain from the pathogenic and other microorganisms. In the duration of rolling process splitting of complex carbohydrates occurs, starch loses its original structure and is easier exposed to enzymes. The dried and cooled flakes have satisfactory flowability, do not set up. Humidity of flakes is not more than 14%, the temperature is not more than 10 °C above the ambient temperature, bulk density is 350-400 kg/m3. Developed set of equipment allows producing cereal flakes, the use of which in feed stuff and rations of young cattle and pigs increases the productivity of animals by 15-20% while reducing feed costs by 12-15%. Cereal flakes are used in the manufacture of complete feed for piglets (pigs at the age of 10 to 60 days), feed concentrates for pigs under the age of 4 months, the calves under the age of 115 days, high-producing cows, sporting and trained horses and lactating mares.
