Summary
Chemical composition and quality of silages from various plants (maize, sunflower, soy and lucerne) or their combinations (maize + soy, maize + lucerne, sunflower + lucerne) prepared in the 50:50 mass ratio. Statistical experimental model was randomized plan while every treatment was done in three replicates. On the basis of obtained results it is found that silages made from soy and lucerne have higher percent of protein, fiber and ash, and lower percent of NFE, compared to maize and sunflower silages. Due to high percent of protein and low amount of sugar legume silages had lower quality, which was a result of lower lactic acid production, higher pH values, significant presence of butyric acid in soy silage and with higher amount of soluble nitrogen. Combining legumes with maize or sunflower the more balanced nutritive value (protein: energy) was achieved, lower degree of proteolysis and acceptable silage quality. Based on the experimental results it can be recommended to combine legumes with cereals and other crops that are easily ensiled – either during seeding period or while filling the silo object, with the aim to obtain favorable silages with both good quality and high nutritive value.
Key words: silage, maize, sunflower, soy, lucerne, mixtures, quality.
