Abstract
Specialists of the Institute of Food Resources of the National Academy of Sciences (Kyiv, Ukraine) have developed a new inoculant, which includes highly active strains of lactobacilli, namely: Lactobacillus plantarum, L. brevis, L. rhamnosus, L. buchneri. All strains were isolated from natural sources. Studies have shown that the use of an inoculant based on lactic acid bacteria in corn silage allows obtaining first-class silage according to the following indicators: dry matter content, pH, lactic acid content, lignin and specific proportion of ammonia nitrogen in total nitrogen. In experimental samples of silage 120 days after the start of the process, the content of dry matter is higher by 8%, crude protein by 0.5%. Silage analysis showed a lactic to acetic acid ratio of 2.62 for the control and 1.23 for the experimental samples, and no butyric acid was detected. Silage from corn, prepared without microbial additives, was not acidified during ensiling to standard pH values, instead, the introduction of lactic acid inoculant made it possible to obtain silage with an optimal pH value of up to 3.9. The addition of inoculant resulted in an increase in ammonia nitrogen to 5.17% of total nitrogen compared to the control of 0.93%
