The effects of bedding straw contaminated on average with 1.4 mg/kg deoxynivalenol (DON) and 0.9 mg/kg zearalenone on the fertility of group housed sows with daily access to pasture was tested using 48 sows kept on contaminated and 48 control sows kept on uncontaminated straw from mating until farrowing. No abortions were observed during the trial. The contaminated straw neither influenced the non return rate nor the number and birth weight of the piglets. The effects of Fusarium toxin contaminated bedding straw on fertility thus seem to be negligible in sows having access to roughage such as pasture grass.

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.
