The influence of natural zeolite on chemical composition and quality of silages prepared from beet pulp was investigated. Beet pulp was ensiled in the sugar producing factory in Pozarevac, Serbia (Serbia&Montenegro) 17 days after their production. The amount of zeolite added was 0; 0.05; 0.25 and 1.25% of dry matter or 0; 50; 250 and 1250 g zeolite per 100 kg of beet pulp. The obtained results show that adding technologically processed zeolite (under the name Min-A-Zel, produced by ITNMS - Belgrad, Serbia&Montenegro) during ensiling beet pulp has influenced more intensive fermentation and increased production of lactic and acetic acid production, with lower pH values and favourable ratio of lactic and total acids. The influence of mentioned doses of zeolite on standard chemical analysis was less pronounced and it is mostly of relative nature.The only real changes occurred as the increase of dry matter and mineral content. The use of zeolite even with material with sufficient fermentable sugars induces more intensive lactic acid bacteria activity since more favourable conditions for lactic acid fermentation.
