Three broiler diets were composed, containing respectively 40% of wheat, hulled buckwheat or raw buckwheat. Respectively 24 male broiler chicken (Ross PM3) were fattened with one of these experimental diets from day 8 to 35 of life. Utilization of energy and nutrients as well as fattening performance and weights at slaughter were evaluated. Although fibre content was clearly higher in raw buckwheat than in wheat and hulled buckwheat, no differences among the diets were found, neither in utilization of energy and nitrogen nor in feed intake, daily weight gain, feed conversion and carcass weight of the animals. Thus, buckwheat offers a potential alternative to wheat in broiler diets, which would possibly include beneficial side effects for sustainable feed production on arable land.

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.
