353 cereal samples (wheat: 193; triticale: 71; barley: 46; oats: 27; rye: 16) were randomly sampled and assayed for deoxynivalenol (DON) and zearalenone using ELISA kits. Positive samples were analysed using GC-MS for DON determination and HPLC for zearalenone determination. DON levels > 1 mg/kg (up to 12 mg/kg) were detected in 4 wheat and in 4 triticale samples, and zearalenone levels > 200 µg/kg (up to 1.6 mg/kg) were detected in 2 wheat and in 5 triticale samples. None of the other cereals contained > 1 mg/kg DON or > 200 µg/kg zearalenone. The percentage of contaminated samples was higher in 2002 than in previous years presumably because adverse weather conditions had favoured fusarium growth. Nevertheless, the percentage of contaminated samples was low and the risk of fusariotoxicosis in animals that consume compound feeds formulated with indigenous cereals is therefore considered to be small.
While botanical composition, growth cycle and phenological stage are integral factors, they are not the sole determinants of the quality of grass silages from intensively managed permanent meadows.
Food that is unsuitable for human consumption does not affect the growth performance or carcass composition of pigs to which it is fed. This makes it a promising solution for reducing food waste.
Horses are ridden or driven on a variety of surfaces, which differently absorb the impact forces exerted on hooves, limbs and the horse's entire body. Objective measurement of the functional properties of equestrian arena surfaces is therefore of great importance.
