- Abstract
BACKGROUND To increase self-supply of protein and phosphorus (P) in European pig and poultry diets and reduce nitrogen (N) and P excretion, attention is directed to approaches increasing protein and P digestibility of rapeseed, sunflower and faba beans. Wheat bran is rich in enzymes degrading and solubilizing protein and phytate. Herein, solubilization of protein, N and P was investigated when increasing ratios of wheat bran were fermented with rapeseed meal ( RSM), sunflower meal ( SFM), faba beans ( FB) or a combination of these ( RSM/ SFM/ FB). RESULTS Protein, N and P solubility was greater, for all mixtures, the more wheat bran was included and the longer the mixtures were fermented. The increase in N ( FB > RSM/ SFM/ FB > SFM > RSM) and protein solubility ( RSM/ SFM/ FB > RSM > SFM > FB) was greatest from day 0 to day 3 and thereafter limited, whereas P solubility increased during the whole period (5 days; FB > RSM/ SFM/ FB > SFM > RSM). In general, FB showed the highest solubility and highest increase in N and P solubility, while RSM showed the highest protein solubility and RSM/ SFM/ FB the highest increase in protein solubility. CONCLUSION Fermentation of RSM, SFM, FB and RSM/SFM/FB without or with wheat bran uncovers a potential for increased protein and P digestibility and thereby reduced N and P excretion from pigs and poultry. © 2016 Society of Chemical Industry
