Eignung von gekeimten Ackerbohnen für die Bio-Ferkelaufzucht

Faba Beans contain certain non-nutritive compounds that can reduce digestibilty and palatabilty in rations for weaner pigs. Germination has been reported to reduce those components. The feeding trial took place with 160 weaner pigs that were assigned to one out of four diets with either 19 % pea (KGER), 16 % raw faba bean (KGAB), 16 % germinated faba bean (VG16) or 24 % germinated faba bean (VG24). Faba beans were germinated for 4 days. Most of the essential amino acids decreased due to germination, the pattern relative to lysine remained the same. There were no significant differences in live weight on day 8, 15, and 22. At the end of the trial live weight of VG24 was significantly reduced as compared to KGAB and KGER, but not to VG16. There were no significant differences in feed intake between the treatments. It was possible to feed germinated faba beans in amounts up to 240 g * kg FM-1 without major reduction in feed intake, although live weight and daily weight gain were reduced. Under the circumstances of this study and considering the effort related to the process, germination cannot be recommended for improving the nutritive value of faba beans for feeding of weaner pigs
