The new ways to efficacy prediction and optimization of grass ensiling
The prediction of the efficacy of grass ensiling taking into account only its sugar-buffer ratio is no absolute reliable. The significant influence on results of ensilage exerts sugar concentration too, which must be no less than 1.5%. This may be achieved by sun semidrying up to 30% of dry matter and to higher values too. On the other hand, the increase in dry matter content exerts the varying influence on milk acid yield, which has to be taking into account by ensilage of various types of grass. The effective way of silage making of nonensiling crops is haylage making. For ensiling of hardly or easy ensiling grass after sun semidrying up to 30% or to higher values of dry matter content the effective method is the use of osmotolerant leavens based on the basis of milk acid bacterial strains and for ensiling of fresh-mown down mass - the preparation Biotroph-111 based on the use of bacteria Bacillus subtilis (strain 111). The sun semidried grass with excessive sugar content may be ensilaged by conventional methods, but a more effective method in such cases is the chemical conservation.
