Study compares wheat bran and beet pulp in weaned pig diets

A new study in Animals evaluated whether two common fiber sources, wheat bran and beet pulp, perform differently in diets for newly weaned pigs. In a 5-week trial, researchers assigned 105 piglets to one of three diets and tracked growth, apparent nutrient digestibility, and fecal scores. The paper adds to a long-running question in swine nutrition: whether fiber source can support gut health after weaning without compromising performance. Earlier work has shown that beet pulp tends to be more fermentable than wheat bran, while wheat bran is more insoluble, meaning the two ingredients can affect digestion and manure characteristics in different ways.

Why it matters: For veterinary professionals and swine production teams, the practical issue is less about whether fiber is “good” in the abstract and more about matching fiber type to post-weaning goals such as stool quality, gut stability, nutrient use, and feed efficiency. Broader nursery pig literature suggests moderate fiber inclusion can help support intestinal function, but higher-fiber diets can also reduce digestibility or energy utilization depending on the source and inclusion rate. Kansas State University’s nursery diet guidance notes that ingredients such as sugar beet pulp and wheat bran are used in part to help manage post-weaning diarrhea risk, while industry guidance from the National Pork Board has emphasized that fiber level and physical properties can materially affect how well pigs use dietary energy and nutrients.

What to watch: Watch for whether this study changes how nutritionists balance soluble versus insoluble fiber in nursery formulations, especially as producers keep looking for antibiotic-sparing and zinc oxide-sparing gut health strategies. (mdpi.com)
