Abstract

The experience of the author regarding fusariotoxicosis, a common and economically serius problem in Hungarian swine herds, is reviewed based on literature data and mycotoxicological research made at the Veterinary Institute of Debrecen. Highly contaminated feed causes typical oestrogen syndrome in sows with persistent (infertile) heat, return to oestrus, sometimes abortions. The majority of the piglets born alive are runts or have decreased viability. In boars, degeneration of the germinative epithelium in the testes causes infertility. Prolonged feeding of feedstuffs contaminated with lower levels of F-2 toxin often causes problems of the reproductive system in pigs. Estrogenism can often be observed in fetuses and newborn piglets. The trichothecene mycotoxins are generally cytotoxic to most cells as they inhibit cellular protein synthesis. Trihothecene toxicoses are characterised by reduced feed intake and sometimes vomiting may occur. Trichothecene mycotoxins also have immunosuppressive effects. T-2 toxin has an adverse effect on the reproductive system of sows. The author gives details of his experiments proving that the so-called fattening lung oedema of pigs, which has been present in Hungary for several decades, is caused by fumonisin B1 mycotoxin, a regular contaminant of maize. The aetiology of this disease was unknown before. Experimental animals showed faintness and slight feed refusal already from the beginning of the illness, followed by the development of severe respiratory symptoms, including progressive hyperventilation. The animals died soon after the first observation of clinical symptoms. Pulmonary oedema and hydrothorax were the most characteristic post-mortem findings but hepatic degeneration was also often observed.
