Although Stein didn’t study the effects of villus height on nutrient digestibility in this study, his group has shown the effect in relation to DFMs in previous research.

Stein’s team also evaluated the microbial community in the gut; some DFMs encourage growth of “good bacteria,” leading to secondary benefits. While the researchers found some minor differences, they couldn’t be attributed to the experimental diets.

The team also noted a drop-off in benefits as the inclusion rate of Clostridium butyricum went up, concluding that a dose of 1,250 cfu per kilogram is sufficient to attain increased growth performance in weanling pigs.

“These DFMs, including Clostridium butyricum, seem to have pretty consistent positive effects in diets for young pigs. I think there’s a good reason they’re being used more and more in the industry. It’s a good return on investment if you add them to the diet,” Stein says.

The article, “Inclusion of the direct-fed microbial Clostridium butyricum in diets for weanling pigs increases growth performance and tends to increase villus height and crypt depth, but does not change intestinal microbial abundance” is published in the Journal of Animal Science. Co-authors include Gloria Casas, Laia Blavi, Tzu-Wen Cross, Anne Lee, Kelly Swanson, and Hans Stein. The work was supported by BASF.
