Feed Contaminant Toxicity

  • PK Gupta


This chapter focuses attention on feed contaminant toxicity that results from toxins such as melanine, cyanuric acid, ionophores, and ureas (nonprotein nitrogen) that represent significant risks to farm livestock and pet animals. In addition, animal feeds and forages contain a wide range of contaminants and toxins arising from anthropogenic and natural sources such as nitrates, heavy metals, radionuclides, mycotoxins, pesticide residues, plant toxins, antibiotic, microbials, coccidiostats, and so forth. Feed and fodder also get contaminated with insect fragments and excreta. Sometimes a compound itself is not toxic, but presence of other ingredients makes the compound toxic. For example, melamine, by itself, has relatively low toxicity. The combination of melamine and cyanuric acid is markedly more toxic to most domestic animals than either compound when given alone.
