Research in Belgium shows that field beans with grain can substitute soybean meal

Tridge summary

Research from the Flemish ILVO institute in Belgium, led by Marta Lourenço, has shown that field beans with grain can completely replace soybean meal in organic feed for laying hens. The study, which compared five treatments, found that silage beans were effective in reducing anti-nutritional factors found in legumes. However, not all soybean meal could be replaced, as the feed would become too moist. The research also indicated that fermenting only field beans and using unpickled horse beans as a substitute for soybean meal were less attractive options due to lower crude protein digestion. The study is part of Belgium's efforts to find alternative regional protein sources for laying hens, also exploring fodder peas as a protein source in a mixed crop with other grains. Other processing methods like toasting or extrusion will also be explored in a separate project.

Field beans with grain can completely replace soybean meal in organic feed for laying hens. According to researcher Marta Lourenço, this is due to tests carried out at the Flemish ILVO. In order to make farming more sustainable, Belgium is also looking for alternative regional protein sources for laying hens. Research shows that field beans with grain can completely replace soybean meal in organic feed for laying hens. Marta Lourenço compared five treatments - a control fodder, fodder with dry beans, silage beans, beans made from a mixture of triticale (summer yield) or from a mixture of winter wheat (winter yield). Before ensiling, the harvest was carried out with the dry matter content of about 77% and the proportion of broad beans about 70%. Silage was chosen as the processing method because it largely neutralizes the anti-nutritional factors (ANF) contained in horse beans. These ANFs are found in almost all legumes and have a negative effect on digestion. Silage can ...
