Stable suspensions for feeding animals (used especially as animal licks) contain 30-50 wt.% water, 3-8 % of free urea, 35-55 wt.% of free sugars, obtained from lactoserum and/or lactose-containing protein liquids and molasses; and 5-20 wt.% of lactosyl and glycosyl urea microcrystals, pref. having a size range of 50-200 microns. Pref. the suspension has a density of about 1.2-1.4 and a viscosity (at 20 deg.C) of 100-1000 centipoises. Animal lick suspension, which is distributed to ruminants by means of a licking wheel (horizontally rotating wheel which passe passes through the suspension picking up the composition, which is licked off by cattle etc). The lick allows urea and ureides to be supplied to ruminants to supplement feeds poor in nitrogen. The method os distribution and the slow decomposition of the ureides avoids abnormally high, toxic blood levels of ammonia. |
