The quality of silage during the conservation of green mass grass with starters "Actinomyces and Saccahromyces Bacterial Drug"

Abstract

The article presents the results of studies of the quality of the silage during canning of cereal-bean green mass in laboratory conditions, with microbiological ferments: "Bacterial preparation based on strains of Actinomuses, suspension" in the amount of 5 ml/t, 27.5 ml/t and 50 ml/t containing Streptomuses venezuele S-806, S-852, S-884, at a concentra-tion of 2ґ109 and "Bacterial preparation based on strains of Sassachomuses, suspension" in an amount of 2 ml/t, 11 ml/t and 20 ml/t containing Саndidа еthаnоliса F-57, at a concentration of 7ґ107 and Sassachomusorsis fibuligera, at a concentration of 3ґ107. The positive effect of the studied starter cultures introduced into the cereal-bean green mass on the quality of the re-sulting silage was established, but it was not the same depending on the starter culture and the amount introduced. The greatest effect on the increase in crude protein was provided by the in-troduction of a starter culture "Bacterial preparation based on strains of Sassachomuses, sus-pension" in the amount of 2 ml/t, which increased the crude protein content compared to the control sample by 1.23% and amounted to 9.08% (in the control sample 7.85%), reduced the content of crude fiber by 0.24% and amounted to 27.60% (in the control sample 27.84%). The percentage of crude ash, both in the experimental samples and in the control one, corresponded to GOST R 55986-2014, but in the experimental samples it was slightly less, and fluctuated within narrow limits of 5.72 - 6.17%, in the control sample 6.26%. The introduction of starter cultures had a more significant effect on the safety of the silage, but it was not the same de-pending on the starter and its quantity. In the control sample, the content of butyric acid was at the level of 0.17%, which corresponded to the second class. The mask "Bacterial preparation based on strains of Sassachomuses, suspension" in the amount of 2 ml/t and 11 ml/t increased the quality of the silage, it corresponded to the first class, butyric acid was not detected. The introduction of a starter culture in an amount of 20 ml/t did not increase the strength class, it corresponded to the second class, but the butyric acid in it was less than 0.14% compared to the control sample and was 0.03%. The starter culture "Bacterial preparation based on strains of Actinomuses, suspension", in the amount of 27.5 ml/t, increased the quality of the silage, it cor-responded to the first class, there was no butyric acid. The introduction of a starter culture of 5.0 ml/t and 50 ml/t did not increase the strength class, it corresponded to the second class, but there was less butyric acid in it compared to the control sample by 0.10% and 0.07% and was 0.07% and 0.10%, respectively.
