You can’t control the weather, but you can mitigate your mycotoxin risk.
Unfavorable weather conditions such as high temperature and moisture allow the natural substances produced by molds to proliferate and produce mycotoxins.
Your existing corn takes on more moisture from the humidity, while the corn in the field is also collecting water. Your sampling may not show an accurate depiction of how much mold is actually in your bins.
Contaminated feeds contaminate profit
Mycotoxins produced during grain storage contribute to an increased pathogen load for your animals in the late summer months. The symptoms from eating contaminated feed can be varied and sub-clinical. Even low mycotoxin levels in feed can reduce performance and profits.
Reduces feed intake and absorption of nutrients
Reduces body weight gain
Impacts overall health status of pigs
While the conditions that cause mycotoxins are unavoidable, you CAN minimize contamination to your animals.
The key is promoting a healthy microbiome. Achieving a healthy gut is a lot like hitting a moving target. There are a number of factors that damage gut integrity – especially in the heat of late summer and early fall months when performance often lags and seasonal diarrhea and E. coli thrive. Understanding that these enteric pathogens are caused by the combination of heat stress and mycotoxins is an essential first step to mitigating your risk.
In the summer, as bins begin to empty to prepare for the new crop, the prevalence of mycotoxins, often associated with cracked or damaged grains found at cleanout often increase. Fumosin is the most dangerous mycotoxin to gut integrity. As grain bins empty and fumosin potential increases, so does the prevalence of E. coli.
