A Comparison of Seven Additives Used in Ensiling High‐moisture Grass/Clover Pastures

Four experiments compared seven additives for ensiling high‐moisture, leafy grass/clover awards in small tower‐silos. The additives were ammonium bisulphate, ammonium monohydrogen phosphate, silotracin, molasses, molassine meal, kylage and protosil 3. In all experiments, silages made with additives were compared with control silages. Apart from molasses, additives had little effect on silage quality: DM and N losses were only slightly reduced by additives. In terms of weight of DM recovered for animal feeding, the additives ranked as follows: molasses and molassine meal > silotracin > ammonium bisulphate, ammonium monohydrogen phosphate, and controls; molasses kylage, protosil 3 and controls.
