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 Požarevac 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 - Belgrade) while ensiling beet pulp has influenced more intensive fermentation and increased production of lactic and acetic acid production, with lower pH values and favorable ratio of lactic and total acids. The influence of mentioned doses of zeolite on standard chemical analysis wa...
