Nine gilts with an initial body weight (BW) of 80 kg were fed a diet contaminated with 2 mg/kg deoxynivalenol (DON) and 0.4 mg/kg zearalenone . Their daily weight gain until 100 kg BW was reduced in comparison to the nine control animals fed the uncontaminated diet. The mycotoxins neither influenced the age at the first observed oestrus nor the fertility of the gilts. Multiparous sows received a diet contaminated with 3 mg/kg DON during one lactation period. In comparison to the uncontaminated diet fed to the control animals, more contaminated feed was refused, but the daily intake of 18 mg DON affected neither the weight loss of the sows nor the growth rate of the suckled piglets. Neither the weaning to oestrus interval nor the fertility in the following reproductive cycle was affected by DON.

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.
