Mycotoxins in Feed for Pigs and Poultry

چکیده
Mycological and mycotoxicological analysis of many feedingstuffs and complete mashes for different animal species and categories have showen that the feed safety problem has been present for years. It is approved that mouldy feed can contain various mycotoxins, but among them in our conditions the most investigated are aflatoxins, ochratoxins, zearalenone and some trichotecenes. Based on laboratory feed inspection of samples sent to be analysed in the Institute of Veterinary Medicine of Serbia in Belgrade it was concluded that fungi and mycotoxins contamination are common. Primarly presence of zearalenone, ochratoxine and aflatoxin was proven. Although these levels usually do not exceed limits layed by actual legislation, having on mind cumulative effects and possibal chronical exposure of animals to their harmful influence, appropriate and competent approach is necessary. In fact, even when direct loses, as concequence of high mortality are not present, indirect loses due to drop of animal performances and production and occurence of secondary infections must not be neglected.

Mycotoxicoses in veterinary medicine: Aspergillosis and penicilliosis
Molds and mycotoxins are contaminants of animal feed causing spoilage and clinical intoxication. Animal exposure to mycotoxins reflects diet composition with major differences occurring between animals kept predominantly of pastures, i.e. ruminants and horses, and those consuming formulated feed like pigs and poultry. Mixed feeds are composed of several ingredients, often sourced from different...

Trichothecenes, zearalenone (ZEN) and fumonisins are the major Fusarium mycotoxins occurring on a worldwide basis in cereal grains, animal feeds and forages. Other important Fusarium mycotoxins include moniliformin and fusaric acid. Spontaneous outbreaks of Fusarium mycotoxicoses have been recorded in Europe, Asia, New Zealand and South America and, in addition, chronic exposure occurs on a reg...

Contamination of food and feed with mycotoxins is a worldwide problem. At present, acute mycotoxicosis caused by high doses is rare in humans and animals. Ingestion of low to moderate amounts of Fusarium mycotoxins is common and generally does not result in obvious intoxication. However, these low amounts may impair intestinal health, immune function and/or pathogen fitness, resulting in altere...

Background: Mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. These fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. Continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. The aim ...

Mould growth in field crops or stored grain reduces starch and lipid content, with consequent increases in fibre, and an overall reduction in digestible energy; palatability is often adversely affected. If these factors are allowed for, and mycotoxin concentrations are low, there are sound economic reasons for using this cheaper grain. Mycotoxins are common in stock feed but their effects on an...

Moulds are capable of reducing the nutritional value of feedstuff as well as elaborating several mycotoxins. Mycotoxin-contaminated feed has adverse effects on animal health and productivity. Also, mycotoxins may be carried over into meat and eggs when poultry are fed with contaminated feed. In a point prevalence study feedstuff used for poultry nutrition in Argentina was analyzed for fungal fl...
