| description | A common method of silage production in Europe is based on the use of cylindrical bales wrapped with polyethylene films. In this study, several modifications of composition of these films were tested for their impact on the microorganisms involved in the ensiling process. Different additives, including nanosilver particles and microcellulose, were analyzed upon the first stage of the experiment. In the second stage, the usability of recycled polyethylene as a film component was assessed. The forage value after ensiling was determined during storage, based on analyses of the content of crude fiber, nitrate nitrogen, total protein, sugars, acids (lactic, acetic, butyric and propionic), pH and dry matter. Microbial forage quality was evaluated by analyses of growth of lactic acid bacteria (LAB) compared to the number of undesirable aerobic bacteria, yeasts and molds. Film properties were also characterized. No statistically significant (<i>p</i> < 0.05) differences were shown for the tested film formulae as compared to standard commercial films. In the second experimental stage, an elevated pH and a slightly higher content of acids were observed for the tested films than for the control sample. In addition, for standard PE film supplemented with nanosilver, a higher number of LAB was detected on the inner surface of the film and in the ensiled material. |
