Pigs, zearalenone

Farmed animals tend to be subjected to compounds that can be classified more easily as drugs. In some cases, animals may encounter compounds in nature that have considerable limitations in inclusion in the diets of farmed animals. An example is the inclusion of zearalenone (Figure 1) and its derivatives in animal diets these have anabolic and oestrogenic properties " and are permitted to be used in some areas of the world but are prohibited from use in others, such as European Union countries. Thus this compound and its reduced isomers (zearalenols, zeranols) improve growth rates in animals but can cause reproductive problems, especially in pigs. Ralgro, which is a commercially prepared derivative of zearalenone, is used as an ear implant in beef cattle as a growth promoter in... [Pg.92]

In fungal cultures a number of closely related metabolites are formed, but there is only limited evidence that these occur in foodstuffs, although there is experimental evidence for some transmission of zearalenone and a- and P-zearalenols into the milk of sheep, cows and pigs fed with these substances at high concentrations. Zearalenone does not degrade at high temperatures (Zinedine et al. 2007), but may... [Pg.422]

A number of emerging methods such as fluorescence polarization immunoassays, dipsticks, or even newer methods such as biosensors have been used for rapid screening of mycotoxin (ochratoxin A and Fusarium toxins—funionisms (FBs), moniliformin (MON), zearalenone (ZON), and type-A and -B trichothecenes in foods, fodders, blood, urea, and tissues of pigs after slaughter) (Curtui et al. 2001 Krska et al., 2007). [Pg.99]

Zearalenone 37 has been found as a toxin masked by glucosylation which undergoes deglucosylation during digestion in the pig. The glycosylation has been repeated chemically likewise for ochratoxin which carries phenylalanine amide-attached to an aryl system. ... [Pg.25]
