The successful use of unprocessed soya bean varieties with reduced content of trypsin inhibitors enables farmers to become more independent in their feed supply. Furthermore, costs for thermal treatment, e.g. toasting, could be saved.
Practical Recommendations
Pig feeding experiments in Austria and Germany during 2017 – 2020 provide following insights for practitioners:
• Since the TIA value can differ between batches, the batch-specific TIA must be known. TIA measurements are offered by specialised feed laboratories (see reference in 'Further Information').
• Unprocessed "Xonia" soya beans with a TIA value of less than 10 mg/g can be included in organic pig feed at 5%. The inclusion rate can be slowly increased up to a maximum of 10%. In doing so, the growth performance should be carefully monitored.
• Other protein-rich ingredients (e.g. peas or faba beans) need to be added into the pig feed to cover the protein requirements adequately. Unprocessed "Xonia" soya beans alone cannot provide enough protein.
• Full fat soya bean is rich in polyunsaturated fatty acids. Consequently, full-fat soya beans should be included to a maximum of 10% during the finisher phase of feeding to avoid negative effects on the texture and stability of the bacon. This recommendation applies independently of the TIA.

EPrint Type:Practice tool
What problem does the tool address?:Soya beans are rich in protein, but they contain antinutritional components such as trypsin inhibitors, which means that thermal processing is required before feeding to pigs and poultry. However, heat treatments are costly and cause damage to wanted nutrients, including protein. Special cultivars of soya bean containing lower levels of trypsin inhibitors have been developed, but there is little knowledge available about the potential of these varieties in organic pig fattening in Europe.
What solution does the tool offer?:Results from recent pig feeding trials in Austria show that heat-treated soya can be replaced with unprocessed (full fat) soya, low in trypsin inhibitors, to up to 10 % of the diet.
