What is mold?

Mold is a term used to describe various fungi that grow in animal feed and degrade the quality of that feed. Mold growth is estimated to reduce feed value by at least 10%. Mold germinates at temperatures as low as 45 degrees F, with most rapid growth at 75 to 90 degrees F. They require humidity for germination, therefore, an upper limit of 14.5% moisture is recommended for stored corn or milo. Other grains should maintain moisture levels less than 13%.
 

 

Molds

A. parasiticus
Produces Aflatoxin. Highly toxic.

A. species (other)

Some useful functions and products. Harmful in large doses.

Alternaria

Common Genus. Problem when ingested or inhaled in large doses.

Aspergillus flavus

Produces Aflatoxin. Highly toxic.

Cladosporium

Common Genus. Not considered a significant problem.

Fusarium (Giberella)

Produces Vomitoxin (DON), T-2 Toxin, Zearalenone, Fumonisim. Toxins called Tricothecenes. All act to decrease feed intake and impair general health.

Geotrichum

Common Genus. Many characteristics resembling yeast.


Mucor

Common Genus. Problem when ingested or inhaled in large doses.

Paecilomyus

Common Genus. Not considered a significant problem.

Penicillium species

Produces Patulin, Citrinin, Rubratoxin and Ochratoxin. Penicillium species are very common. Seldom causes problems except at high doses.

Rhizopus

Common Genus. Problem when ingested or inhaled in large doses.

Scopulariopsis

Common Genus. Not considered a significant problem.


Interpretation of Mold and Yeast Levels

Mold Count
1,000-10,000 Relatively safe
10-000-100,000 Transition zone
100,000-10,000,000 Caution advised
10,000,000+ Do not feed

200,000-300,000 Think about getting mold identified

Yeast
1,000,000 High

Results: Smell, stomach upset off feed, maybe be able to neutralize with buffer
