摘要

feed composition based on livestock urea coated for sustained ruminal release, and process for its preparation. The present invention is particularly concerned with a urea-based food composition which gives urea the sustained release characteristic of the animal's rumen. The present invention further relates to a process for preparing said food composition. The food composition according to the present invention comprises, by weight, from 20 to 99.2% of urea, from 0.2 to 20% of hydrophobic coating based on animal or vegetable waxes, and may additionally comprise from 0.1 to 10%. melting point modulating agent and plasticity, from 0.1 to 10% of a hydrophobic carrier, from 0.4 to 20% of drying agent, from 0 to 10% of sliding drying agent and from 0 to 10% of drying agent. plasticizer.
