Biological conservants impact on the silage quality and aerobic stability
There were showed the technological trial results of the corn silage conservation with using the new generation microbial additives. There were characterized the main advantages of biological inoculants and their influence on the silage quality, nutrients preservation, energy value, and the forage aerobic stability.
The place reaction and the hydrogen-ion concentration (pH) are the most important regulators of the microbiological and the biochemical procedures. We can observe this index in our control samples in 60 and 120 days after the silage making. The index was 4.1-4.0 and 4.0-3.8 relatively.
The silage making with inoculants gives us the quick sugar bacterial fermentation. It helps to make the sufficient volume of the milk acid and the acetic acid.
It was found out that the control silage sample had the least value of the milk acid comparing to the determined organic acids (62.31%). In the mean time we had 63.59% with the ‘Litosyl plus’ and 67.81% with the 11C33 inoculant. In addition to that there were 37.67% of the acetic acid in the control sample (without inoculants). There were 29.16 and 32.19% of the acetic acid in the trial samples consequently. Silage without inoculants had the butyric acid in the equivalent of 0.02% in comparison with the trial samples where we did not find it.
This was established that during the storage period the ‘Litosyl Plus’ conservant using at a dose of 4 g and the inoculant 11С33 using - 1 g per 1 tone of silage mass provided the dry matter losses reduction at the level of 3.63 and 0.33% vs 4.98% in the control group.
