Experimental data on the effectiveness of the use of the chemical and biological preparation for the conservation of rolled corn. The effectiveness of the use of preparation was determined by organoleptic indicators, acidity, acidification rate, organic acid content, chemical and nutritional composition of the feed, comparing them with the option of preserved without the use of preparation (control). Digestibility and energy nutrition were determined by calculation using formulas taken from the guidelines for assessing the quality and nutritional value of feed. Digital material was processed by the statistical method of small samples with establishing the reliability of the difference (P) between the options on a PC using the Microsoft Office software package. As a result of research, the effectiveness of the use of formic acid in pure form, as well as in a mixture with ammonia 85:15, with ammonia, propionic and benzoic acids in the ratio 50:20:2:10, 40:40:2:5 and AIV for the preservation of rolled corn. They allows acidifies feed for optimal acidity value necessary for long-term storage of feed and maintain it throughout the storage period, increases the content of raw and digestible protein, feed units, metabolic energy in the resulting feed.
