Description
Inoculants were tested to determine their suitability for use as silage aids. Studies carried out in laboratory indicated (1) that the minimum inoculum should be at least 105 viable organisms per gram of fresh fodder and (2) of all bacterial strains tested, only the Lactobacillus and, specifically, L. casei improved storage characteristics. But the efficiency of an inoculant was subordinated to the fermentable sugars content of the crops. In this respect, alfalfa and second cut grass had the lowest potential for ensilage. Energy was supplied as a mixture of milled barley and amylolytic complex. The influence of a 1: 1: 1 mixture of Lactobacillus ( L. casei, L. plantarum and L. coryniformis) at rates of 105 g-1 fresh weight with an energy sur 1ply was examin_ed i�� relation to a con:imercial additive containing 1 a mixture of Streptococcus faecalis and L. plantarum (10 g- ) and to formic acid at rates of apphcat10n of 0 and 4.0 g kg- fresh weight. Untreated and S. faecalls-L.plantarum treated silages were badly preserved. Only formic acid and Lactobacillus inoculant had desirable effect on preservation. The latter silage additive was more effective than formic acid, particularly with respect to the amounts of isobutyric and butyric acids and of ethanol. A high amount of lactic acid was produced with the Lactobacillus inoculant, leading possibly to lactic acidosis. In order to decrease this risk, it is essential to select strains producing the L ( +) isomer of lactic acid.
