Evaluation of a novel insoluble fiber source on growth performance and fecal dry matter in nursery pigs using different formulation strategies

Lay Summary

Carbohydrates that are not digested by mammalian enzymes are classified as dietary fiber. Although fiber has historically been associated with reduced performance in weaned pigs, recent work has demonstrated its role in promoting intestinal health and modulating gut microorganisms, which may reduce the incidence of post-weaning diarrhea. ValoproWin is a novel insoluble fiber source with a purified source of fiber, oat hulls and yeast autolysate designed for nursery pigs to support gut health; however, no published papers describe its effects on growth performance. Therefore, three experiments were conducted to assess optimal conditions to successfully utilize ValoproWin in corn soybean meal-based diets and its effects on growth performance and fecal dry matter including feeding duration (0, 10, or 24 d), inclusion level (0 to 5%), and formulation method (diluted or adjusted). Considering the results of the three experiments collectively, the addition of ValoproWin did no effect overall growth performance; however, it consistently increased fecal dry matter.
