Abstract

1357042 Cattle feed SOC FRANCAISE DIES SILICATES SPECIAUX 21 Jan 1972 [10 Feb 1971] 3050/72 Heading A2B [Also in Divisions C2 and C3] A cattle feed comprises a supported urea obtained by contacting an adsorbent carrier material with an aqueous solution of urea and then partially drying the impregnated carrier such that the urea is not subjected to a temperature exceeding 125‹C. The carrier may be silica, an aluminosilicate or a silicate.
