EFFICIENCY OF PREPARATION SENOSIL FOR PRESERVATION SILAGE

The fulfilling of National program of enhancing livestock productivity and efficiency is impossible without creation a reliable feeding base which largely determines products quality and price. The article evaluates efficiency of corn ensilage by homo- and heterofermentative bacteria Lactococcus lactis ssp. lactis biovar diacetilactis, Streptococcus thermophilus, Lactobacillus acidophilus, L. plantarum, L. brevis, L. rhamnosus, L. paracasei ssp. paracasei, Propionibacterium shermanii subsp. shermanii. The experiments confirmed a high biological activity of production strains. Tests of bacterial starter culture «Senosil» in the conditions of livestock farms showed that its use guarantees a reduction of dry matter and nitrogen losses; the resulting silage is rich in vitamins and organic acids. Inserting the bacterial starter culture influences microbiological and biochemical processes development in the most active way, by suppressing the development of unwanted microflora, thus promoting lactic acid fermentation and inhibiting butyric acid fermentation. The ratio of organic acids in silo has been changed to a better side. Lactic acid content in the feed was higher with by 6.4 % and acetic acid - by 26.5 % as compared to conventionally harvested silage. Presence of butyric acid in the first and second samples has not been detected. As a result, a more rapid acidification in the experimental silo inhibited livelihoods of unwanted microflora, namely yeast, mold, and butyric acid bacteria. Active acidity of treated silage was at the level of 3.9 and provided the acidity necessary to suppress the development of putrefactive microflora in feed. High biological value of the feed is provided by probiotic microorganisms, members of the leaven, and the products of the transformation of vegetable raw materials. The number of lactic acid microorganisms is three orders of magnitude higher than rot. Butyric acid bacteria in the silage with ferment were not found. Silos, preserved with the starter help, mostly provides fodder needs of the animals, helps to normalize digestion of animals, improves feed digestibility, as the level of digestibility of starch in the test sample was greater than 12 %, and the rate of silage use by 6.5 %, which, in the final ultimately affect the efficiency of livestock.

Biological and economic evaluation of corn silo with use of the developed "Senosil" preparation, as well as the economic justification of practicability of this starter use for silage feed in productional conditions showed its effectiveness and demand by production. Corn silage technology using bacterial starter "Senosil" is widely used in a number of Ukrainian enterprises.
