How to Manage Feed Hygiene

Feed hygiene is usually managed by using technologies including heat treatments or/and the use of feed additives containing organic acids and formaldehyde.

Heat Treatment

Heat treatment is very effective tool for killing bacteria but there are factors such as the initial contamination of the mash feed and the amount of time in the conditioner which will affect the efficiency of the heat treatment. Weaknesses of heat treatment includes certain types of Salmonella being resistant (S.senftemberg, S.thomson) and effects on moisture and cell damaging.

Feed Additives - Organic Acid

Organic Acids are also frequently used to attain feed hygiene. Though it has the toxic effect to microorganisms in the gut, it"s disadvantages includes being mostly only effective in low to medium level of contamination and could potentially require higher inclusion for high level of contamination.

Feed Additive – Formaldehyde

A chemical disinfectant such as formaldehyde has a well-known efficiency. Formaldehyde’s disruption of pathogen cell membranes and denaturation of pathogen proteins makes it particularly effective against vegetative gram-positive, gram-negative bacteria and mycoplasma. It has a mode of action complementary to organic acids, such as propionic acid, which disrupts hydrogen pumps and causes an increase in pH, impairing normal cellular processes. Comparison studies have shown that a combination of formaldehyde and propionic acid is stronger than either component alone because it acts at two different levels.
