Fiber in Animal Nutrition

33 Conclusion derived from fresh, debarked wood (Arbocel) or pure cellulose which are transformed into a functional fiber via HPC fibrillation. These highly concentrated (>60%CF) fibers with a water binding capacity up to >800% can help fulfil fiber recommendations in feeds for piglets, sows and hogs. Focusing on the fiber content of feeds ma- kes it possible to address important topics in swine nutrition like gut health, satiation, faeces consistency, digestibility, water intake, tail and ear biting etc. and finally translates into good animal performance.
