Cattle fodder contg. urea - coated with hardened tallow and/or hardened fish fat to retard ammonia release to paunch

摘要

Cattle-fodder consists of urea coated with pref. >10 (>15) esp. 20-40 wt.% hardened tallow and/or hardened sea-animal fat, i.e. hydrogenated animal and fish fats, having m. pts. 50-70 (55-65) degrees C. The fodder serves as a non-protein nitrogen source for ruminants, e.g. bovines. NH3 release to paunch is retarded, e.g. from 70 to 26 mg NH4-N/100 ml gastric fluid, after 1 hr, by adding 38% tallow fat having m. pt. 59 degrees C to urea.
