Abstract: Objective: This study was carried out to determine the effects of lactic acid bacteria inoculant, enzymes and lactic acid bacteria
inoculant+enzymes mixture on the fermentation, cell wall content, aerobic stability and in vitroorganic matter digestibility characteristics
of sunflower silages. Methodology: Sunflower was harvested at the milk stage of maturity. The treatments were as follows: (1) Control
(no additive), (2) Inoculation of lactic acid bacteria (LAB, 2 g t1, a mixture of Lactobacillus plantarum and Enterococcus faecium applied
at a rate of 6.00 log10 CFU LAB g1 of fresh material) (3) Enzyme (E, 150000 CMCU kg1 for cellulase and 200000 SKB kg1 for amylase) and
(4) LAB+enzyme mixture (LAB+E, 2 g t1 a mixture of Lactobacillus plantarum bacterium (6.00 log10 CFU g1) and 150000 CMCU kg1 for
cellulase and 200000 SKB kg1 for amylase). After treatment, the chopped sunflower was ensiled in 1.0-l special anaerobic jars, equipped
with a lid enabling gas release only. The jars were stored at 25±2°C under laboratory conditions. Three jars from each group were
sampled for chemical and microbiological analysis for 2, 4, 8 and 60 days after ensiling. At the end of the ensiling period all silages were
subjected to an aerobic stability test for 5 days. Results: In addition, in vitroorganic matter digestibilities of these silages were
determined. Both inoculants (LAB and LAB+E) increased characteristics of fermentation but impaired aerobic stability of sunflower silages.
Lactic acid bacteria+enzymes mixture inoculants decreased neutral and acid detergent fiber content and than control silages.
Conclusion:In vitroorganic matter digestibility was numerically increased for treated than control silages.
