Sulphite waste powder and mineral feedstuffs - used to obviate unnecessary ballast when pelleting feedstuffs

摘要

A tabletting aid for pelletising feedstuffs comprises 80-95 wt.% powdered sulphite waste (I) and 5-20 wt.% of a feedstuff mineral (II). No unnecessary filler is included in the feedstuff so that the unit nutritional value is increased. (II) includes calciferous materials (e.g. powdered limestone, ground chalk or dolomite or pptd. CaCO3), a P-contg. mineral powder (e.g. a defluorinated dicalcium phosphate or bone meal freed of organic matter) or MgO/MgCO3.
