Research report: Effect of a 3 strain Bacillus-based direct-fed microbial on growth performance and intestinal concentrations of volatile fatty acids in nursery pigs fed low- or high-fiber diets

Increasing the inclusion of dietary fiber in nursery pig diets may stimulate beneficial gut microbiota and reduce post-weaning diarrhea. However, the digestibility of nutrients and energy is decreased in high fiber diets. Nursery pigs fed diets high in fiber have been shown to have reduced ADFI and G:F.

Bacillus-based direct-fed microbials (DFM) secrete a large amount and a wide variety of fiber degrading enzymes. It is thought that feeding DFM may offset some of the negative effects of  a high fiber diet. Therefore, an experiment was conducted to test the hypothesis that addition of a Bacillus-based DFM will increase fermentation of dietary fiber and improve growth performance when fed to nursery pigs.

Press release: Soybean meal produced in U.S. has greater energy values when fed to pigs than previously estimated

URBANA, Ill. – Differences in soil type, variety of soybeans, climate, or processing conditions can cause the same crop to have different nutritional value when produced in different locations. However, feed composition tables combine values from crops grown all over the world. Results of recent research at the University of Illinois indicate that book values for energy in soybean meal underestimate the energy value of soybean meal produced in the United States.

"In the experiments we've conducted using soybean meal here at the University of Illinois, we have calculated values for digestible and metabolizable energy that were consistently 200 to 400 kcal/kg greater than values in feed composition tables," explained Hans H. Stein, professor of animal sciences at Illinois. "Most of those experiments have been conducted using soybean meal derived from beans grown in Illinois. So we decided to compare soybean meal from Illinois with soybean meal produced in other states, to determine if our results were due to better nutritional value of soybean meal produced in Illinois."
