Ensilage of whole crop wheat is popular in Europe and America for feeding of ruminant animals, but it is quite rare in Hungary. It can be introduced for replacement of shortage of silomaize silages in drought season. The quality of wheat silage could improve by biological inoculants. Silage additives are expected to ensure a more efficient fermentation phase as well as reduce the risk of aerobic deterioration when silages are exposed to air. Many additives have been developed to improve the ensiling process and nutritive value of silage. Nowadays the 3rd generation biological inoculants –containing lactic acid bacteria and enzymes – are used in order to coordinate the fermentation in such a way that they increase lactic acid production at the beginning of the fermentation and improve the quality and stability of silage during the fermentation and feeding. The quality of raw material (maturity of plant, chop length, spreading of inoculant uniformly) and the proper filling, compacting, covering and wrapping have a great influence on the effectiveness of the inoculant. The mycotoxin content of malfermented silages is an undesirable risk factor. The objective of our research was to determine the effect of two silage inoculant strains Lactobacillus buchneri and Pediococcus acidilactici mixture combined with amilase-, glucanase-, xylanase and galactomannase enzymes on whole crop wheat silage fermentation characteristics, nutritive value and aerobic stability compare to untreated control. Experimental ensilage procedure started with the basic whole crop raw material originated from waxen ripeness of wheat (hard cheddar stage of maturity of seeds) at the time of harvesting. The DM content of chopped raw material was 44%. The LAB inoculants were applied to raw material at 2.5x105 CFU/g fresh material (FM). Because of quite good quality of untreated silages also, the priority of LAB treatment could not proven in the aerobic stability test. The biological preservative (LAB+enzymes) promoted better fermentation and forced back the undesirable butyric acid production in the silages.
