In organic farming, appropriate protein feeding is challenging based on regional or farm-grown resources. Therefore, feeding maize-bean-silage to dairy cows and
fattening pigs could be a viable option to increase the protein content in the diet. However, anti-nutritional compounds might impair animal performance. When exchanging maize silage with maize-bean-silage in the diet of dairy cows, no detrimental effects could be detected. Similarly, the on-top feeding of maize-beansilage to pigs revealed no differences in regard to animal performance compared to a
grass-clover diet. Thus, the inclusion of a certain amount of maize-bean-silage in the diet of dairy cows and fattening pigs had no negative effects on the animals. Further studies are going to examine the effect of higher proportions of maize-bean-silage
