Pharmaceutical use of zinc oxide in piglet nursery diets is on the way out in the European Union. Strategic use of dietary fiber is a strong alternative in protein-dense feed.
Figure 1. Butyric acid production increased by 23% in 15kg piglets when fermenting soluble fibers (left) while protein fermentation was reduced by 19% (right). Control = no fiber, HP FiberBoost = soluble non-starch polysaccharides (NSP), Lignocellulose = insoluble NSP, SCFA = short chain fatty acids, BCFA = branched chain fatty acids
Figure 2. Quantification of the total carbohydrate content (64%) of a commercial nursery diet by two analysis methods. With the proximate analysis (A), 16% of the fiber fraction remains unknown. The enzymatic-chemical analysis (B) identifies all carbohydrate fractions.
