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.

In both sport and alternative agriculture, horses are once again being used as draught animals. Efficient power transmission plays an important role in the wellbeing of draught horses.
A study by Vetsuisse shows that the outdoor veal calf concept reduces antibiotic consumption in calf fattening by 80%. AGRIDEA has examined the economic viability of outdoor veal calf production and concludes that it cannot compete with conventional veal calf fattening.
In contrast to pigs, dairy cattle are as yet rarely fed protein-reduced diets. Studies show that there is also potential for protein savings in cattle, and thus for reducing ammonia emissions.
