Ways of ensiling of

festulolium and corns

Kosolapova V., Osipyan B.

The purpose of the studies: give the estimation of efficiency of ensiling of perennial cereal rubbed

and corns with preparation, created on base of homolactic fermentation and heterolactic fermentation bac-

teria, and the level of influence of the given preparation on aerobic stability ready stern is defined.

Use of biological preparation on basis of homolactic fermentation and heterolactic fermentation

bacteria under ensiling of freshness masses of festulolium promotes the reduction of the volume of the

stood out products of the fermentation by 1,5 -5,0 once and obtaining of forage of 1 and 2 quality classes.

The Preparations on basis of heterolactic fermentation bacteria such as Biotrof 600 and Biotrof 700 pro-

vide the aerobic stability of the silage. The losses of the nutrients, after opening of capacity with proven-

der, were 5-fold less, but visible colonies of musty fungi appeared for 2 days later, than in silage with

homolactic fermentation bacteria.

Under ensiling of garter festulolium most losses of the nutrients noted in silage, stored up without

preservative. The content of the oleic acid equal to 2.09 % and pH 4.88 pointed to impracticability of si-

lage to feed. In silage, prepared with Biotrof 600 and Biotrof 700 content of the acetic acid has formed

8.64 and 6.01 % in dry matter that promoted the aerobic stability of silage. The losses of dry material af-

ter opening of capacity have formed at the average 2 %, under ensiling with homolactic fermentation bac-

teria - 5%. The visible colonies of musty fungi in variant with Biotrof 600 and Biotrof 700 appeared for 2

days later.

Under ensiling of corns of milk-waxy ripeness best variant on product of the fermentation were a

silages, stored up with homolactic fermentation bacteria. The volume of stood out gas of the fermentation

in they formed 9.92-11.35 l/kg of dry matter, in variant with heterolactic fermentation bacteria – 15.03-

14.47 l/kg of dry matter. However preparations on basis of heterolactic fermentation bacteria provide the

best aerobic stability. The content of the acetic acid was high in silage stored up with Biotrof 600 and

Biotrof 700, where the heterolactic fermentation bacteria dominated. Due to greater producing of the ace-

tic acid heterolactic fermentation bacteria, as well as most full use of sucrose at periods of the fermenta-

tion the loss of the nutrients from aerobic damage were similar to chemical preservative and 5-fold less,

than in rest variants.

Key words:
