Grain of filmy cultures activation by a disintegration method

Oats and barley possess all necessary fodder properties, but contain more than 10 % of cellulose in their structure which is of little use in feeding of mono-gastric animals (poultry and pigs) as cellu-lose interferes with interaction of fodder substratum with intestinal enzymes. The sense of activation consists in destruction of walls of crude cellulose by method of a high milling. The purpose of the study was the definition of opportunity and features of filmy cultures activation by disintegration. The study was performed on the basis of laboratory of new fodder means of Novosibirsk state agricultural uni-versity. From technological positions the grindability of wheat is optimal, as its thin fraction makes 74 %. The grindability of grain wastes and barley is lower than 6 and 4.7 %, respectively, which easily meets the requirements of further using of obtained flour in feed pellets preparation. Thus the fractional structure of oats at this operating mode of a mill does not meet the imposed requirements. By selec-tion of different grain mixes (with inclusion in their structure of cultures with the high content of cellu-lose after activation with use of disintegrator in the form of a manual mill) there is a real possibility of application filmy grain crops and their combinations as full-fledged fodder means in feeding of mono-gastric animal. Researches showed that among filmy cultures barley’s activation ability was high. When opening the gate for 75 % the ratio of fodder particles of thin and rough fraction makes 69.3: 30.7 %. Oats activation ability at the similar mode is insufficient; a ratio of thin and rough fractions is 4.0:52.0 %. Activation of combinations of filmy cul-tures defines satisfactory quality of the flour. The variation of thin fraction was within 62.6-66.7, rough fraction variation was 33.3-37.4 %.
