How much energy and nutrients a pig can use from the feed depends greatly on the feed ingredients, feed level, and the physiological stage of the animal. Fibers are of great interest because they can improve health and welfare of pigs and co-products from the food and agriculture industries are among the most interesting. The ability to degrade different fiber sources and utilize energy and nutrients are poorly understood in gestating sows, but highly important when formulating the feed composition. The hypothesis was that sugar beet pulp was superior to the other three fiber-rich sources investigated: soy hulls, palm kernel expellers, or a mix of fibers, with respect to intake and utilization of energy and nutrients. We did not find sugar beet pulp to be particularly superior with respect to energy (fermentation or utilization), whereas utilization of nitrogen was highest for sugar beet pulp but compromised in the three other diets depending on fiber sources.
