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. Methods of reducing disease in animals, reducing doses of antimicrobial drugs in animal feed, and reducing drug residues in meat products are disclosed.
