Aflatoxicosis caused 20% mortality in feeder pigs due to contaminated corn feed. Environmental factors like cold weather and corn processing likely increased aflatoxin production and disease severity.

Area of Science:

Veterinary Medicine
Animal Toxicology
Mycotoxicology

Background:

Aflatoxicosis is a significant health concern in swine, particularly feeder pigs.
Mycotoxin contamination in animal feed can lead to severe health issues and economic losses.

Purpose of the Study:

To investigate an outbreak of aflatoxicosis in feeder pigs.
To identify the causative agent and contributing factors of the disease.

Main Methods:

Histopathological examination of affected pigs.
Detection of aflatoxin B1 in pig serum and feed.
Analysis of corn for aflatoxins B1 and B2.
Evaluation of environmental and feed processing factors.

Main Results:

Related Experiment Videos

Mortality rate of approximately 20% in feeder pigs.
Histopathology confirmed aflatoxicosis.
Aflatoxin B1 detected in pig serum and corn-based feed.
Aflatoxins B1 and B2 identified in the source corn.
Feeder pigs were more susceptible than adult swine.

Conclusions:

The outbreak was confirmed as aflatoxicosis caused by contaminated corn.
Corn harvesting and drying methods likely promoted aflatoxin production.
Environmental conditions, including cold weather, exacerbated the disease's onset and severity in feeder pigs.
