This ProRefine Practice Abstract provides practical recommendations for ensiling legume forage stems in order to support the implementation of biorefined forage legumes as high-quality protein sources in the European organic sector, while also giving value to the fibrous co-products. This will contribute to strengthening the agricultural sector in Europe improving the integrated utilisation of local resources.

Making silage from legume forage stems - learn it here!
What problem does the tool address?:
Field fractionation of forages can separate the leaves and some top stems, rich in protein and low in fibre, that can be used in the diets of monogastrics. The residual stems, still represent a valuable wet feedstuff for ruminants that needs to be preserved. With haymaking, most of the leaves still attached are lost.
What solution does the tool offer?:
Ensiling is the best option - the process of making silage. But stems have a high moisture content that can lead to high seepage and unfavourable fermentation. Wilting to 30 - 40% dry matter avoids seepage. The addition of soluble sugars as molasses at 50 kg/ton of fresh forage directs the process towards lactic fermentation and improves silage quality. Mixing wet stems with dry beet pulp or cereal meals at 100 – 200 kg/ton of fresh stems enables ensiling of the unwilted stems and improves the fermentative and nutritional value of the final silage.
