An enzyme improves the feeding value of field beans in a broiler diet


There is a need to investigate the use of home-grown protein for inclusion in broiler diets to replace expensive imported soyabean meal. However, potential high protein UK-grown feeds such as field beans can reduce diet digestibility and lower growth rates of broilers, because of their high tannin content.

The main aim of this study was to investigate the effect on dietary energy levels, nutrient availability and growth performance of broilers, by supplementing a diet based on field beans with the enzyme tannase.

The study concluded that supplementing the field–bean based diet with tannase, improved feed efficiency, availability of nutrients and apparent metabolisable energy
