Description
Summary:Prevention of metabolic acidosis, tympania of the rumen during the fattening of cattle is an important issue in the production of beef. Researchers are actively searching for available substances and evaluating their effect on fermentation of the ruminant cicatrix. Perspective in this regard may be the use of organic acids in animal nutrition. The following samples were prepared for the study: crushed barley + distilled water (control); crushed barley + 0.5% solution of lactic acid; crushed barley + 1.0% solution of lactic acid; crushed barley + 2% solution of lactic acid. The digestibility of dry matter and starch in the artificial scar (in vitro), depending on the concentration of lactic acid and 30 min exposure, was studied by exposure for 3 and 6 hours. The experiment found that the processing of ground barley with 0.5%, 1% and 2% lactic acid contributed to the decrease in digestibility of dry matter by 26.7-32.2% and starch by 16.1-21.1% 3 hours after incubation. A 0.5-1.0% solution of lactic acid is optimal for use, as it effectively reduces the availability of starch for the cicatricial microflora of ruminants.
