Studies on the occurrence of the mycotoxins ochratoxin A and zearalenone in pig breeding herds, with reference to clinical changes in the genital tract and mammary glands of piglets up to ten days old


, : Studies on the occurrence of the mycotoxins ochratoxin A and zearalenone in pig breeding herds, with reference to clinical changes in the genital tract and mammary glands of piglets up to ten days old. Untersuchungen zum Auftreten der Mykotoxine Ochratoxin A and Zearalenon in Schweinezuchtbestanden mit Berucksichtigung klinischer Veranderungen am Genitaltrakt und der Mamma an bis zu 10 Tage alten Saugferkeln: 161 pp.

Ochratoxin A was present at up to 5 ng/ml in 302 of 505 serum samples from 341 sows, 154 gilts and 10 boars of 70 herds. Zearalenone was present in 4 of 115 feed samples (av. concn 12.5 mu g/kg) but it was absent from 132 serum samples and 8 faeces samples. Of 4113 male and 3954 female unweaned piglets, 14% of males and 7.8% of females had reddening of the teats, while 0.9% of males and 22.3% of females had mammary swelling. The vulva was swollen in 12% of female piglets.
