The Effects of Lactic Acid Bacteria and Lactic Acid Bacteria+Enzyme Mixture Silage Inoculants on Maize Silage Fermentation and Nutrient Digestibility in Lambs

This study was carried out to determine the effects of lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants as silage additives, on the fermentation, aerobic stability, cell wall content, and nutrient digestibility in lambs of maize silages. Pioneer 1174 (Iowa, USA), and Maize-All (Alltech, UK) were used as lactic acid bacteria and lactic acid bacteria+enzyme mixture inoculants. Plant materials were fermented for 60 days in bunker type silos. Aerobic stability test was applied to all silos opened in the end of fermentation period. Relating to silage fermentation analysis of pH, ammonia nitrogen, water soluble carbohydrate, organic acids (lactic, acetic and butyric acid) were carried out and microbiological analyses had been done. Digestional value of crude nutritive matters of silages determined with classical digestive experiments. Both inoculants increased characteristics of fermentation but impaired aerobic stability of maize silages. Inoculants were not effect on the nutritient digestibility of silages. Lactic acid bacteria+enzyme mixture inoculant decreased neutral and acid detergent fiber content.
