Mycotoxin Occurrence, Toxicity, and Detoxifying Agents in Pig Production with an Emphasis on Deoxynivalenol

Debora Muratori Holanda et al. Toxins (Basel). .

Abstract

This review aimed to investigate the occurrence of mycotoxins, their toxic effects, and the detoxifying agents discussed in scientific publications that are related to pig production. Mycotoxins that are of major interest are aflatoxins and Fusarium toxins, such as deoxynivalenol and fumonisins, because of their elevated frequency at a global scale and high occurrence in corn, which is the main feedstuff in pig diets. The toxic effects of aflatoxins, deoxynivalenol, and fumonisins include immune modulation, disruption of intestinal barrier function, and cytotoxicity leading to cell death, which all result in impaired pig performance. Feed additives, such as mycotoxin-detoxifying agents, that are currently available often combine organic and inorganic sources to enhance their adsorbability, immune stimulation, or ability to render mycotoxins less toxic. In summary, mycotoxins present challenges to pig production globally because of their increasing occurrences in recent years and their toxic effects impairing the health and growth of pigs. Effective mycotoxin-detoxifying agents must be used to boost pig health and performance and to improve the sustainable use of crops.

Keywords: aflatoxin; deoxynivalenol; fumonisin; mycotoxin detoxification; mycotoxin frequency; mycotoxin toxicity; pig.

Parameter estimates of regression models for the percentual changes in growth performance variables in pigs challenged with multiple mycotoxins. (A) Percentual changes in the average daily gain (ADG), average daily feed intake (ADFI), and gain-to-feed ratio (G:F) caused by supplemental deoxynivalenol in the feed when all other variables remained constant. (B) Percentual changes in the ADFI and G:F caused by supplemental aflatoxins in the feed when all other variables remained constant. (C) Percentual changes in the ADG, ADFI, and G:F caused by supplemental zearalenone in the feed when all other variables remained constant. (D) Percentual changes in the G:F caused by supplemental fumonisins in the feed when all other variables remained constant. (E) Percentual changes in the ADG and ADFI caused by increasing the days of the challenge period when all other variables remained constant.
