Contamination-resistant animal feedstuffs.

摘要

A formaldehyde-treated animal feedstuff which is resistant to contamination by pathogenic bacteria is obtained by spraying an aqueous solution containing 10-50 wt.% formaldehyde on an animal feed, to obtain 200-1000 g/ton of a hydrolyzable formaldehyde adduct with a coefficient of variation 7% or less. Method for preparing such animal feedstuff and method for raising livestock.
